Q: are the valve guides original? If so, then the OEM spec valve guide seals ought to fit perfectly. If, on the other hand the valve guides were replaced, perhaps they were machined to an incorrect OD in the area that the seals fit and that is making the fit with the valve guide seals loose? I would recommend fitting new valve guides now that you have it apart - that way you can choose to (a) go for OEM dimensioned guides and stick with OEM valve guide seals, or (b) fit some guides that are dimensioned to take the VAG valve guide seals whilst being the correct length and major OD to fit the heads (this is obviously a custom machining job, but simple enough if you have an OEM VAG valve guide and a 308 valve guide for reference).

Excellent stuff Jack. ALWAYS good seeing the Influenzo work-in-progress. Teflon valve guide seals are never going to seal as well as the 'rubber' style ones that will have some flexibility to slide on the valve stem while holding back the oil. One thing I used to do on 'K' series engines for Caterham Se7en use was remove the spiral spring around the actual valve stem of the seal. Reason ? They had been known to break. If there is minimal 'slop' in the valve guide the seal alone is enough. Thanks for the content. Great viewing!!!!!!

Cracking on and finally seeing the light at the end of the tunnel seems so rewarding-well done! Your exhaust headers seem a bit crusty. There is much to be gained by ceramic coating them inside and out. Besides looking infinitely better, the coating acts as a thermal barrier and keeps the exhaust heat inside the pipes where it belongs, to be exhaled through the muffler, rather than radiating through the pipes and heating up the engine bay. The process was pioneered commercially by an outfit called Jet Hot here in ‘Murica, but I have to assume it’s readily available there too. Insist on a place that fully dips (submerges) the pipes, rather than simply spraying the outside. Normally they are a dull silver color, but if original appearance is valued you can then use standard exhaust paint over the coating, which will then hold up so much better because the paint won’t be subjected to nearly as much heat as it would if it was sprayed directly onto the bare steel pipes.

New modern seals may need guides with the tops machined to hold those seals. Not the end of the world but will add quite a lot to your bill. Consider that before the shop does lots of work on reseating the valves etc. That will need to be done all over again if you fit new guides.

With that part that holds the valves and cleans the oil off of them, I would find out what they did on the ferrari 328 and see if it can be retrofitted, maybe even call up and talk to that guy Matt Farah is having do his ferrari 328 and see what he recommends as a good OEM or better than OEM supplier as he has an instagram, and contact info posted as he just did a video and a huge update on it, and he would know the car pretty well as he has a white 308 he keeps as a personal that has been on Jay Leno's garage as the 308 is a car made at the low point in ferrari's and performance car history while the 328 was made at a peak when they were finally modernizing their cars for the US market thanks to the popularity of magnum and Vice and forest buller putting the cars into the public conscience and Magnum even used multiple 308's, namely a last year QV for its last two seasons, as they used the whole range of 308's in that show, the Jimmy James Dean Special that was featured in the cannonball run that was the car and driver test car in 77, then an 81 GTSI with fuel injection, then an 84 QV so I would imagine theirs been some changes even in the 308 line for things such as that to help with that, like maybe this part is better or worse latter on, like see what they did and find a solution. as maybe the latter QV used a stronger piece or they completely binned it and redesigned it for the 328 and its a simple swap over. also with your car what is it, a 308 that has been converted over to fuel injection, as it doesnt have the I on it yet, where it says 308 GTS, when it should be 308 GTSI I think you said its fuel injected like did someone convert it over and forget to overhaul some bits on it?

From my experience using PTFE ie virgin PTFE is a disaster and useless for this application and many other applications as it has no mechanical strength at 150c , it cold flows and also expands massively as well, hence that spring clip. Junk them. The OEM ones are more likely filled PTFE anyway. Fit the modern ones . Probably Perfluoroelastomer / Kalrez ? I would also check the valve guide heights are correct and not too low and also the valve to stem clearance as really exhausts should work fine without seals.

Reminds me of the Ford CVH which had a tendency in early versions for the seals to ride up the valve stem. Ford solved that by adding a big base plate the size of the valve spring to hold it down. The seals looked like a ten gallon hat but it worked. If this was me, I'd add a dab of industrial epoxy (not Araldite, something designed to take the heat) to keep them pinned down. A question, is it possible to change the seals with the heads on? Compressed air in cylinder method or TDC method if the piston pockets are not too deep?

If Ferrari used 3 different suppliers to supply parts and they are Company 1 -- 2 and 3 ! If you bought a part from company 2 and not labeled as in a Ferrari container than it is an OEM part. Although they made it for Ferrari as an OE part it could have been custom specked for a particular reason although company 2 makes that part and sells it, unless it is a Ferrari part it is an OEM.

You have my utmost respect for doing this yourself because most Ferrari owners won't even clean their car themselves, let alone do the mechanical work, but I must make the comment that you are learning as you go along. I'd be interested to know the fit of the valves in the guides (I suspect they're OK) because in truth, if the valves and guides are in as new condition, the stem seals don't really have much work to do. We run most competition engines without stem seals because a) we know everything is in good nick and b) because it's one less thing that can break up and cause problems; smoking and oil consumption are never a problem under these circumstances whether the engine be a pre-crossflow pushrod engine or a 16V BDA. Now it looks like your bore wear may be fairly good (but it needs measuring), but so far as I can see from the video, your cross hatching is absolutely minimal. The entire face of the bore should be cross hatched (ideally with a plateau honed finish) and with no polished smooth areas at all. The tiny grooves of the cross hatching actually retain minute quantities of oil as the pistons go up and down and it is this that lubricates the rings. Oil that is attached to the bore wall like this doesn't really burn because it is kept cool (relatively) by the bore wall itself that is in contact with the water jacket. Ideally, you need to pop a piston out (yes, even as a non-Ferrari specialist I know it's not the work of a moment) and inspect the rings for wear and perhaps more importantly, check that they haven't relaxed and lost their tension against the bore wall. You're doing a lot of work if you put it back together and find it's just the same.
@sumkunt0r
2 жыл бұрын
Great advice Roger. I was going to comment the cross hatching was partially worn away - It looks to me that only the deeper grooves were left. I think it is a good idea to measure the bores whilst the head is off. This is a job for someone experienced with the tools. @Number 27 Do you know anyone with correct size bore comparator who would visit you and measure the size and taper of the bores? Admittedly It is better to do this with the pistons removed but if you have a large amount of taper between the top of the bore and the bore above the piston at BDC It's an Indicator you might need a rebore What would I do? - Fix the heads and try it, If it still burns oil then at least you know the heads are good. 🤞

Old Ferrari street engines never had valve stem seals fitted at the factory. I remember a story about Steve McQueen complaining about his 250 Lusso burning oil. After the Ferrari dealer tore down the heads & couldn't find anything wrong, he took it to a mechanic experienced with Ferraris & found there were no valve seals, which, apparently was de rigeur for Ferrari. Seals fitted; no more burned oil.

Caution: You said you had turned the engine over several times with the heads off but I don't see any hold-downs for the cylinder liners. My advice is to NOT do that anymore as you run the risk of compromising the base seals. You can make a hold-down with a large washer and a length of PVC pipe over the head stud. You need 4 of them - one between 1-2, 3-4, 5-6 and 7-8. Either intake or exhaust side, doesn't matter.

Extremely good point! This is a wet liner engine but fortunately designed in the traditional 2 "O" ring manner. Rotating the engine with heads removed (and no liner clamps) will have disturbed the "O" rings. They may now leak - or maybe not. If they leak - it will be from a vent hole between the two "O" rings (on the block). If you want to do a proper job - number the liners and send then out for honing (to remove that bore polishing). With the "O" rings removed, set the "liner stand out" Ferrari quotes this - there are various ways of achieving this. Now fit the "O" rings with rubber grease. Bolt the head back on and if you've done the above correctly - you'll have a reliable car. If you want to save 10K of getting it right - just fill the cooling system with £5 of "rad weld" and it will be fine.

Easy for me to say as I collect British classics in an entirely different price range. But when I acquire a new I car, I pull then engine and trans, at the sign of any issue, have everything measured and inspected replace what needs to be replaced, get any machining done that needs to be done and am done with it. The key is to find an expert happy to advise on the way one should build each particular engine and trans. Time is a beautiful thing, it exposes all the design flaws from stock and solutions are developed, if you have the right advice, assembling a fresh rebuild isn't difficult, its resolving all the known flaws and which direction to take to achieve this that is difficult. For the cost of doing everything three times you are probably close already to having done a full rebuild once properly. There are improvements to every classic car engine that those that know do on every build, if its a car you are going to keep, thats the way I would do it, then it's done and you can actually use the car. Next episode....... so the bottom end is a bit tired, now I need to have the heads disassembled carbon removed, new valve seals and do the entire thing again in addition to the bottom end. Or even worse, valve stem seals didn't work, resolve that and revert to prior statement. Get expert advice and sort it top to bottom. The doing is easy, knowing what to do, not so much.

I am unsure if I missed it, but why did you not simply remove the engine? Removing the engine seems to be a lot of work, but it is not (about 6 or so hours) and the positive to this it allows you to easily and effectively inspect and review other parts of the engine. Also, removal of the cylinder heads can be challenging, as over time a bit of corrosion/electrolysis occurs between the aluminum head and the head bolts (steel)... which in a number of cases requires the use of a metal plate "puller". In the end I suspect that there was little to no time savings doing this work with the engine in the car and in fact would actually consume more time than a full engine out.

Yeah mate, make sure you put those stem seals on the inlet valves and not the exhaust! Only saying. There's a little known mod here in the UK at least. Evacuated sump/crankcase. Moroso sell them. It's a heat proof one way valve firing crankcase pressure down the exhaust. The exhaust acts like a Syphon and can give negative crankcase pressure when revving. Higher your revving, higher the vacuum. So no oil leaks, cylinder contamination and cleaner less black oil. The other desirable side effect is a mild turbo effect on the under side of the piston on induction stroke. Win win. Check out moroso check valve and vac pumps. Cheers e buona Fortuna!

My late Dad was an Alfisti from 1971 'til the day he died, never owned anything but various 105's from then until 2015. In the UK days before he repatriated to Oz (in1982) he had an Alfa and BMW-trained Italian mechanic called Mike Sasso (who he'd found back when he was running Cooper S's). He had a GT Junior 1600 from 1979 on, a really nice one but which had lost a bit of performance by 46K miles (IIRC) and he had Mike take the head off for a looksie and overhaul ... BUT - Mike made it clear that before he'd do the work he'd have to be sure the pistons, more particularly the rings, would be able to withstand the restoration of as-new compression (which he decided they could), the risk being wafer-thin rings "blown-a-to pieces" somewhere down the line, as he described it in his Roman accent. Of course he had to gauge that by examining the bores, as you just did with the 308 ...

Hi Jack, Watching you struggle removing the front cylinder head and manifold, begs the question... Surely it would be easier to drop out the engine as a unit, wouldn't it? That way, firstly there'd be much better access, and secondly, should the bottom end need any work, it's already out. Just a thought....
@dalemanolas5994
2 жыл бұрын
It's not a subframe so it doesn't drop. There are rails underneath the transmission. You actually lift out the engine and transmission as a unit. It's a bugger because the access is tight and you don't want to scratch the paint. It's also a lot of work to disconnect everything. You very definitely need one man on the crane while you find out what is hanging this up and guide the engine+trans out. I wouldn't do it unless there was an actual problem with the bottom end. I'd fix the valve stem seals then enjoy hammering that engine until the compression went bad. It's a lot of money to grind the crank, and get a re-bore with new pistons and rings and bearings. Nothing comes cheap from Ferrari.

Remember that cylinder liners are also wear parts. The liners shown in video looks polished due to normal wear. Some honing scorers are visible but obviously most is worn out. A new good honed liner has a matt surface with small scored lines criss cross, this is to ensure that the oil film stay and lubricate the piston skirt and rings. At 16:05 shown a surface mark that looks like metal fatigue, this can be changes in the metal structure due to wear and age. And might be a sign that the liner start to reach the end of its life. Again remember that pistons, rings and liners are wear parts that needs to be overhauled and replaced at some stage in an engines life, some sooner rather than later specially on a Ferrari. All the best.

We used to use ford valve seals(2a DOHC engine from sapphire) in VW's as they fit better due to the mini barbs on the capment ring and you can swap the in/out seals to match the needed size.

Being totally ignorant of these things I have to ask, wouldn't it have been better for access and working on just to take the whole engine out then disassemble the various parts?

Forget about originality, if parts was bad from manufactury,just replace it with more reliable and better ones.This is the right way, i think.

All I can say is that you must have the patience of a saint. Hope apon hope it is just the valve stem seals. You deserve abit of luck for all the time and hassles you have had with the car. I don't fancy putting the front exhaust back on again. Yup your right there's just no room to work. Best of luck with the engine rebuild and hopefully hopefully that's the end of it. Everything buttoned up for the final time. You deserve a medal for all the hassles you've had. At least you can final enjoy the Ferrari you bought.

Id be tempted to pull that sump and have a look at them rings the bores need glaze busting for a start sump gasket and a set of rings are not expensive while you are in there

In a nut shell you should only use VITON valve guide seals. It's a high temp resistant, soft plyable synthetic material that can move side to side with a rocking valve stem. No guide seals will SEAL long if the valve stem to guide clearance is excessive. Your letting the wrong machinist work on your heads. Sorry, I realize this is too late a response to this episode, but your in over your head and should have had someone like Iain Tyrrell perform the repair. Those cylinder bores ARE worn, glazed, need honing with new rings. Cheers from a 47 year now retired factory trained German car technician in New Hampshire 🇺🇲👍

Jack. An interesting video. I think I speak for all your channel followers, we love the 308. However, this is my 70 year old humble opinion: my son's car (vauxhall SRi Turbo 16 valve) had 6 valve stem seals that came adrift, causing lots of blue smoke on startup and after long periods of idling, but very little when revved and running and it never fouled a plug. I have to agree with other comments, you MUST remove the engine, strip it fully and measure/inspect everything properly. I would bet good money that the plug foul-up and blue smoke is ring/bore related. There is certainly next to no honing on the liners. Remember, there are many engines with no valve stem seals by design, and they don't foul plugs up, they just use a bit more oil than you would like.

I’m sure you’ve covered it, but are the cams a std profile. Unknown to me, my 72 Alfa GTV has high-lift cams: after a top-end rebuild (due to bent valves…) the engine was burning oil badly. Turned out the std stem seal position was no good for the high-lift cams and they had been damaged. Just seems a little odd that you have had this issue. Why haven’t more people suffered? Perhaps they have? Thoroughly enjoy the videos, especially since I recognise many of the roads you use, so presumably you are relatively local.

General advice when disassembling anything for repair work or other reasons. Get some plastic bags like those sold for food storage etc. Place all of the fasteners and related hardware in labeled bags. For example Left Bank Exhaust Manifold Screws and Washers. Also it is a good idea to write the fastener size, type and grade on the bag. In the US we used bags for U-Line in various sizes. Also on this engine I would imagine the head should probably be replaced due to being torqued to a certain setting and then being stretched. Say 70nm + x°

I started my search for a 308 or a C2 Corvette here in the states just after you bought your 308. I watched many of your early shows and saw what you had to go through on so many levels that I am now a proud owner of a 1963 red Corvette. I had to do some updating of tires and brakes but nothing like you have had to do. I also have the advantage of being able to go to almost any auto store and buy parts for the small block Chevy V8 something you have not been able to do. You were an inspiration to me and in a major way helped me buy the car of my dreams. I admire your can-do spirit and hope all turns out well for you. F I A T aka Fix It Again Tony is still in play!

I love the C2 also and would be proud to own one. I also lust after a 308. But they are apples and oranges. The 308 is a road racer and the C2 is a muscle car which handles like a F150. Good for straight power and speed but not much of a cornering machine. But if you just want a classic car that you can sit in and think of it's provenance and smile, you made the right choice. Being able to source parts and easily work on it yourself is an important thing.

@@boyracer3477 I agree entirely with your assessment. I love them both for two very different reasons. I did finally choose the C2 for the reasons you mentioned and Influenza had a lot to do with my choice. I still think the 308 is one of the best designs but it is just too difficult to maintain at a reasonable cost.
