funny how the bearing that spun is between the 2 ground stud's, id say it was grinding wheel dust/metal contamination. if the studs needed grinding they should have been removed from the engine, never grind near an open engine, grind wheel dust is the worst thing to have inside an engine.

On top of that, reducing the height of the nut can reduce the tension it is capable of effecting on the bearing caps by reducing the grip length, it gets worse if an angle grinder has been used and the nut hasn't been retorqued afterwards.

From what I've heard if it's added in motor oil, it will run a while before anything odd turns up.

@@davelead2742 I heard it about 30 years ago, from a couple guys that were in their late 60's then. I'm not sure how it would work with some modern filter technology now. But I can tell you I had a Russian tractor in here with a centrifugal oil filter. It had liner seals go bad so the guy dumped copper seal leak stopper in it being a cheap fix, It didn't fix the leak like he thought. it dumped the coolant again a week later. on inspecting the sump contents I couldn't find the copper color trace in it like you'd see in coolant. when I opened the filter to clean it that's where the copper colored particles were in the carbon and slime in there. It had gone round with the oil/water mix inside the oil galleries/bearings and that filter got it all out. It kind of makes me think the valve grinding compound would go round the same But the paper filter wouldn't get it all out as those centrifugal filters are far more accurate in what they take out and can tell you how hard an engines been working from carbon deposits between services that paper type won't show.

It would have helped to have the oil filter to open up and see how much rubbish is in there and were the remote oil lines to the filter cleaned out after the first engine let go probably not! but I agree with what you said in your video oil starvation due to the poorly made gasket on the pickup, an oil pump would rather suck in air than oil, also a dry sump would have been a much better idea. Many years ago I worked for an engine re-conditioners and we sold short engines which consisted of rebuilt block, pistons, crank and cam shaft, most camshafts were in the block back then anyway we sold a little A series for a Midget about two week later the engine came back under warranty knocking badly customer claimed, we striped the filthy engine to find none of the parts he had removed from his old engine had been cleaned still a layer of sludge in the bottom of the sump he had evan reused the old filter and oil which was black there is no accounting for the stupidity of some people, when he returned he was shown the door very quickly.

where is the Oil pan and the Pickup tube... i have run into many issues with poorly designed oil pump pickup tube and oil pickup screens.. the pickup not deep enough in the pan.. had one customer made oil pickup... that was made with perforated sheet metal. the holes were tiny and spaced too far apart unlike a screen with the holes the same size but only the thickness of the wire between the holes so there is a lots more surface area... i also HATE flat oil pickup surface shapes.. i like a nice convex shape.. so there is a low pressure area of oil being pulled up.. a flat surface to the pickup screen or grill allows the oil to slide away leaving the pickup exposed. . since he keeps bringing it back.. and it previously expired on the dyno.. something is wrong in the oiling system.. since the engine was rebuilt twice and the oil pump changed several times.. it leads to the Pickup /oil pan issues. excessively thin oil.. question.. have you ever set up an oil pump dynometer.. so you can check the flow rates and pressure at various pump speeds .. used to have an oil pump rebuilder in los angeles that would also take used oil pumps from warranty returns and flow /pressure test them for you.. i would really like you to measure the end gear clearance of the returned pump.. a JPaydirt on youtube ended up with a Peterbuilt dump truck with a Cummins N14 diesel.. pump specs were 4 to 8 thousands of an inch of gear to case end play.. all the replacement pumps and he went thru several trying to find a good one .. china from several brands.. even factory cummins were china pumps with 0.008" end play.. he had the pump housing lapped to take it down to .005 and ended his low pressure oil problems.. there was a video of another tuber building an N14.. washing the pump... the solvent went thru the pump so fast it was like going down a drain. a comment i made on a Circle track or stock car racing magazine a bunch of years ago.. resulted in somebody reading it and on GM revamp of the LS1 the LT1.. they actually build a swiveling engine dyno.. that rotated the engine at various loads to angles that duplicated the forces changing the oil levels around in the pan during acceleration.. cornering and braking. check youtube for Chevy LT1 tilting Dyno.. i don't know if ford in europe has done like ford in america and replaced the oil pressure sending units with a reversed oil pressure switch... open contacts below 5 psi and closed above 7 to move the gauge up off zero part way.. if you end up building another one of these engines for that person.. weld some 6x1.0 nuts to the side of the oil pump pickup.. so the pickup can't be blocked by the oil pan being pulled up by an incorrect PCV system without a crankcase vent system.. without a crankcase vent system.. using a pcv only.. oil pans have been sucked up and blocked the oil pump pickup screen.. had a friend with a race Honda H22 ... insane build.. 14 to 1 compression drag race engine... had a Vacuum sump set up.. it sucked the front crank and aux shaft seals in.. had to find flanged seals.. and glue the rear main seal in place. ended up going to a GM electric smog pump... turned on as he lit the second stage light.. ran a vacuum/turbo boost gauge hooked up to his crankcase.. to make sure he did not over pressurize or over vacuum the crankcase.. causing issues. thinking of that insane raspy honda.. i did a paper napkin drawing of a tuning tube that fit in at the 3 bolt collector after the flex joint.. it tapered the pipe diameter down from 2.5" to 1 3/4" and was almost a foot long. this increased the speed of the exhaust gasses after the collector.. at 7,000 RPM on the hub chassis dynos.. he went from 265 horse power to 275 by just installing the first try at a tuning tube.. also totally changed the way the car sounded. instead of sounding like a raspy honda.. it sounded like a healthy big block chevy. it was insane the difference a tuning tube caused. he had closed loop fuel injection also. so it could compensate for the change in scavenging on the engine and the change in manifold vacuum,

If it was in good condition compared to the one in the engine when it failed then it tends to rule out any common factors between the two. If the bolts were ground down then surely that must have been before the first pump was fitted ?

If you had fitted the sump and the remote filter assembly, you may have noticed other possible running problems like oil pickup and other problems related to oil pressure and that the two studs needed reducing in length ?

I am not wise enough to know, but years ago we ran an Essex V6 in a light car with a front well sump, under hard acceleration it would briefly lose oil pressure. After one too many hard launches from the traffic lights the engine started to knock, it did nothing like this carnage. (We made a baffled sump when we fixed it). I realise this engine had a home made pump gasket but chances are it was in one piece when fitted. I think you are right on the money, the swarf from the grinding did the pump in. It would be interesting to know if the original oil pump was damaged too. You have to wonder too whether the remote oil filter assembly was contaminated when it was fitted. A shallow sump on a high revving engine may not be too clever if it has no windage tray and the pickup might have been far from optimal, a shallow sump with a stock pickup will encourage it to pickup crap that would otherwise sit in the bottom of the sump. Was the sump also "clearanced" with a grinder at the last minute? TBH I think there are too many unknowns to reasonably uphold a warranty claim, the wrong viscosity oil is the least of the problems. IMHO you can give a bit of "goodwill" but this engine was damaged by subsequent work, not by the original build......

I would guess it has been sucking air, either from the crap gasket or due to the poor sump design (most likely cause). Even an oil pump with that much damage will produce good enough oil pressure. The debris damage is consequential in my opinion. I work on off highway engines and anything that needs gradeability (if wet sump) needs / gets a deep well sump. Another thing that would worry me is that the oil pick up pipe has a minimum distance from the sump bottom, beyond that flow can be messed up. And these are usually set close to minimum by design. Messing with the sump clearance would not be good. High level assessment... Would i expect a on highway engine to survive in a off highway application. No!!!. Not without modification. And a shallow sump is not one of those modifications

You could try and if the warranty claim was valid and the customer took you to court you would have to show how manipulating the hardware caused the issue. When the customer wins their case, like i said its a valid warranty claim, not only would you have to fulfil all warranty clauses but pay court fees and legal costs of the plaintiff. Even the stickers on consumer electronics that indicate manipulation have no value in court. A, it isnt 100% reliable B, there are nondestructive methods to open electronics C, the sticker doesnt affect functionality. Simply opening something does not break it and the courts in the US and UK have acknowledged this.

It sat at 28 to 40 psi all day no matter what stupid angle we had it Idling at. Basically the customer tried some tricks and they didn’t work out. (And the outcome seen appears to match the modifications mentioned) (as a weird engineering note; ironically you are better with a narrow sump that carries half the oil than wings that let it hide from the pickup)

The warranty you offer will be based on 'road-legal' use, on public highways. So all driving must be between kerb stones on tarmacked road surfaces at road legal speeds that exclude drag-racing from a standing stop, or "entertainment" loops at car meetings. Put another way, anything a vehicle insurer will cover them for on public roads. The history to this situation is pretty obvious. Intermittent oil starvation and the use of light oil caused problems with the bearings while being run off-road. (O to 30 oil is only used by manufacturers to improve fuel efficiency.) It's probably why the engine got trashed at the dyno remapping gaff. He's trying to make the lubrication system do something that physics says can't happen. The customer needs to learn how important the lubrication system is, and how "DIY" attempts at trying to rewrite the laws of physics regarding liquid flowrates and viscosity seldom work. They now have made two attempts at 'designing' an oil recirculation solution that has failed both times. Dry sumping isn't cheap, but it would have been a whole lot cheaper than wrecking two engines - with likely a third on the way: the one they are using at the moment. It looks like you have been caught up in a 'design solution' research project. No warranty issue here.

Can’t believe anyone would grind a stud with the sump open!! And surely if the issue was clearance then the sump would be in place whilst taking off the visible excess!!!! My money ( in the absence of anything more obvious - Would be air ingress from the poor oil pump seal. A decent slug of air in any high pressure hydraulic system usually results in no consistent pressure at all! Be it water, fuel or oil…. As for the original complaint of low pressure “ Shallow sump in a trials vehicle!! Is just asking for trouble!!! Even a standard sump on a Subaru track car can cause carnage when you add a bit of centrifugal force, , tip it on it’s side and you’re sure to be sucking air, there’s a reason why manufacturers exclude competition use from warranty claims, mechanical abuse, high revs and slow speed, total lack of mechanical sympathy and never getting the full story!!!!… to name but a few!!!!! 🙄

I'd ask to see the non standard sump .. if using the enging in a rock crawler, would need to have the sump baffled to maintain an oil level, for the oil pump.. when the engine is Running Hard at Stupid angles.. Just a Thought .. Or as you said a Dry Sump system would be so much better ... I'd show him the Current bill, for the works done to date, and give him a High repair price to have the work done.. Hopefully he will just scrap the engine and take it away from your shop..... Never to be seen again .. Andy Mac..

Admire your work but I’ve no idea why you’re taking on jobs like this. An engine that’s already been rebuilt and failed = red flag. An engine that the customers wanting to make their own sump and use for rallying = red flag. Anything modified in the slightest I wouldn’t be touching considering how busy the engine machine places are around here doing standard car engine rebuilds. Just asking for grief surely working on modified old Cortinas 🤷🏻♂️

It's obviously no fault of your company... But it also seems that the poor bloke has had no luck with that engine... As you already have the engine strip down I would offer to replace the bearing caps and do a dry sump conversion at cost for him... A bit of good will goes a long way plus he is parts of your local racing community and word-of-mouth goes a long way for a small business like your own

If you get low oil pressure warning, then you stop as soon as it is safe to do so. Then get it repaired! How long did he drive with no oil ? Never carry on and hope if fixes it self. If you know you have an oil problem and carry on, then it's your own fault when when it gets damaged. He should have brought it back and shown you the oil pressure problem, What exactly was he doing! driving at 45 deg off road with oil all at the wrong end of his sump? Was he using the wrong extra thin oil trying to get more power?

Another dimwit customer that thinks he is a engineering genius. That grinding dust definitely went into the engine, that's why the pump rotors look bad. The gasket is a shocker. The crack would cause aeration and the overlap would cause cavitation also damaging the pump rotors. This damage is all the customers own fault.

When I sold turbochargers warranty was the worst part of any given day. People would pop a turbo, bolt a new one on, and pop the new one with all of the shrapnel from the old turbo and then demand warranty. As if it was in place for their mistakes. They rarely would figure out why the old turbo went bad then they would wonder why the new unit only lasted 6 months. It was MY fault every time of course.

I wouldn't even bother with a warranty claim, hes been pissing about with it cocked it up and blaming you, chances are when he was grinding those bolts down iron filings went everwhere, also these mazdas need the correct sump and proper location of the filter, you said it was a remote filter which indicates it was piped off somewhere else well that alone will play havoc with pressures take a lot longer to run up to pressure even worse if he's using thin oil.

Great video. There is a difference between oil pressure and volume . No worries with pressure but suffering from lack of volume Wrong pan will suffocate the pump
@matthewq4b
2 жыл бұрын
There is not really a difference. Pressure is an effect of volume. If you have insufficient volume you will never achieve adequate pressure. Pressure is the effect of restriction against the volume of the liquid being moved. Lower the volume and you lower the pressure. Increase the volume and you increase the pressure. Change the viscosity of the liquid and you have to change the volume being moved to maintain the same pressure. Either increase the volume for a thinner liquid or decrease for a thicker liquid. The preceding applies to loss lubrication systems such as the oiling system in an engine. Closed systems the preceding may not apply.

I like your videos. I am an old mechanic from the US. I would never, ever let someone walk out of my shop with an incomplete engine. In fact, I always made sure we installed any engine rebuild in the car before we let it leave. In addition, I would insist as a condition of warranty that they return the car for inspection and oil change after 2000 miles. There is just so much that can go wrong as evidenced by the warranty claims I have seen here. help me understand why you do that, you must have a good reason as you seem to be a very smart guy.

I think you did the right thing taking it back and checking it out. I suspect it is a combination of the problems you mentioned. The flat sump may not be suitable for the highly angled terrain he is using it for. I suspect the the oil pick up is running dry when the vehicle is at extreme angles.

i dont agree it was the spec of the oil . more like the sump he made for it lacks capacity , i do agree a dry sump system is required . also the oil presure relief valve needs to be checked . the split in the gasket would not help but i dont think its the cause at all . the bearing spun because it got hot due to low pressure and not due from the grinding of the bolts
