I love seeing people using these. I have a 6.5 599 block in my 1991 FJ80. I pulled it from my 2500HD a couple of years ago. With 180k on the engine, the cylinders still had good cross-hatch. Bottom end looked like new with no visible cracks. I did find cracks between valves on the heads at the rear cylinders. I cleaned it out and put new heads on with ARP studs. I added all of the updated cooling components along with the best fan and clutch I could find. HX35 turbo, 4 inch in, 3 inch straight out. I'm only running 15 lbs of boost. It's a little hazy pulling hills but EGTs are good and it has plenty of power for the Land Cruiser. I can get nearly 20mpg on the highway with 4.10 gears, 35s, and full-time 4wd through the 4l80e.

My first experience with the 6.5L Turbo was while working at a Chevy dealership. We had to pick up a small fleet of trucks we had to sublet for modification. I chose a route back which took me over the back roads with some seriously steep hills. I was amazed at how the truck I drove pulled up the steepest hill, it kept accelerating as we climbed which wasn't an easy task for most vehicles. I also wound up seeing a fleet of these trucks towed in with blown engines. The truck shop mechanic simply stated much of this was probably due to what he called misuse -- driving it like a gasoline engine, winding out at high RPM or excessively lugging it. Otherwise he insisted it was a good engine. Over the years, with the experiences I've had working in the automotive repair industry, I have to agree; if properly maintained and not overly abused, they can be an efficient and durable engine. And who doesn't love that old school "clacking" of an old school IDI diesel?

Helpful helper tip: If you want grease on engine parts that won't be assembled for a while, ATF assembly grease is a great option because it withstands pressure and dissolves in oil. But if you don't have that around, plain old Vaseline petroleum jelly works just fine. It stays in place and readily dissolves in oil. It doesn't offer much resistance to pressure, but as long as your oil pump is working, it should be fine.

Diesels have come a long ways. Used to be a member of the Diesel Page, the motherload of all light duty GM diesel info except the Olds 4.3l and 5.7l, but was holding back long enough until the right deal for 03 Cummins with the 6 spd came around and never looked back. Learned my GM diesel lessons on a 5.7l Custom Cruiser. Heath Diesel and Kennedy Diesel used to be the go to shops for all 6.2/6.5 aftermarket developments. What a rip off finding a $9k long block not being balanced to the 9th, but may be considered within spec. I don't know. You must have another $1.5K in it building it the right way. Anyway, the 92/93 MY 6.5l were considered the best years before GM switched to the electronic drive train management. Great video production for my entertainment pleasures and a like and subsripe for keeping those family heir looms on the road and keeping dad busy. Somehow I do miss that Texas drawl, though ... hm...?

Great video, awesome to see you and Pops working together :) And no such thing as labeling too many things when building an engine! Thank you for sharing the small details like tool part numbers. Did you remember to gap your rings before installing? A new set doesn't guarantee proper clearance Every P400 part is still available except for the block or full engine. The best head upgrade for a 6.5 is to run P400 heads, they have hardened valve seats and will resist cracking better than the stock Optimizer heads or any aftermarket one Also a word of advice to anyone installing timing gears- Don't assume they are plug and play. There's a recent aftermarket set that have the dots off by one tooth and several engines have had valves hit pistons and trash engines. At a minimum use the old timing chain set dots to align the cam and crank before putting on the gears Thanks for giving the 6.5 some love, they definitely have a trash reputation because of GM's penny pinching but when built and maintained properly can be a very reliable and easy to work on engine

Nice video. On the gear drive, ive heard from old timers that they can cause a harmonic that kills crank shafts or the nose of the cams in the 6.2 or 6.5. I’m not sure how true that is but just something you might look into just incase. Any 6.2-6.5 stuff I’ve dealt with I’ve talked to Heath about, they had the land speed record with one back in the 90’s I believe.

Thanks very much for watching. I’m glad you enjoyed it. I’ve heard the same about gear drives, and disregard their comments completely. Timing chain slack is far more concerning, especially for these engines with only a few thousandths clearance from valve at piston at TDC. Gears are broadly superior to a chain, though more expensive to install.

@WillometMotorFab Glad I found the channel too! Funny story. One of my best friends growing up in high school acquired a 92 or 93 silverado with a 6.5 shortly after graduation. The thing had a bad compression skip and was blowing a ton of white and blue smoke. Pulled the head on the bank with the dead hole and found a severely scored cylinder. From there we pulled the oil pan, removed the piston from the bad cylinder, honed the crap out of it till all the vertical lines/scoring were gone. (Really should have been bored but he was broke as was I). Put the original piston back in with a new set of rings, buttoned the motor back up and the thing ran like a top! Albeit it always had a little bit of piston slap on that cylinder until it warmed up afterwards. Ended up driving it for 4 years after that going back and forth to Northern Arizona University and it was still running pretty decent when he sold it! 6.5 DDs aren't as bad as people make them out to be.

I drove a 99 GMC dually for ten years that had the 6.5 turbodiesel. I loved the engine, although it was the "weak sister" compared to the Cummins, Power Stroke and D-Max. One of the worst things on that engine, and easiest to replace for more power, was the downpipe out of the turbo. It had dings and dents from the factory to allow for clearances, but it was so restrictive the engine couldn't breathe. I installed a Banks aftermarket downpipe that made the engine feel like it had grown a couple of cylinders. I had always heard the engine was good for 300+ hp when done correctly, but it was said the main bearing caps would shatter (like it looks like your 6.2 did), unless a girdle was added with side bolts into the caps (making each cap cross-bolted with 6 instead of 4 bolts). I notice your new engine doesn't have the girdle, is that due to better metallurgy on your build, or is the girdle really not needed? Awesome build, I sort of wish I still had that old dually.

It's the block's main webs that crack. The outermost 10mm bolt holes on up through the cylinders, and area around the oil squirters. The cast iron cranks are also very prone to the two part self-modification phenomenon if either the damper or the dampened pulley fails. If your rebuilding a later gen 6.5L? It's money well spent to have all the sharp edges radiused or feathered near the main journal webs and the bottom of the cylinders. They are ALL stress risers, IE crack starters.

@@WillometMotorFab- I have two 2005 military takeout Optimizers. Neither had forged cranks, and both have oil squirters. The Optimizers squirters aren't the typical bolt on tube assemblies. Rather they are pressed in orifice plugs located on the bottom ledge of the cylinder/main web interface. If you don't run the three hole main journal bearings they're blocked off anyway. They are points of stress-riser (IE, crack points), but hard worked turbo 6.5's greatly benefit from the piston cooling they provide. Helps with the infamous cylinder #7/8 radial cracking phenomenon.

You can never go wrong with the old diesels. Sure they left much to be desired hp wise. They had a real chance at lasting 500k+ miles though and made enough torque to be fantastic work trucks. I have a modern 2011 duramax and while I love it, I love my 93 7.3 IDI turbo way more. Its probably gonna hit 700k miles in the next few years. Only major breakage was 1 turbo and 2 sets of injectors. It needs glowplugs since the early 2000's but I have plenty of ether.😂

It was designed to bolt up to a 4L80E! Off the top of my head, I remember 255HP/520Lbs-Ft Tq. Oh and BTW, the mono-block means the head is part of the block, IE no head gasket!

@@WillometMotorFab The main issue with the p400 in many gm applications is the oil pan. The p400 uses a special structural cast aluminum oil pan that was designed for a specific application. At one point a couple of companies were offering modified versions of the cast aluminum oil pan and one company was in the process of having their own oil pans cast but I can't remember if they ever brought them to market before the engine was discontinued. I had a customer with a 98 suburban that experienced a broken crank due to the failure of a balancer and I installed a p400 in it and I had to modify the oil pan to clear the front differential which was the main problem. That was when the p400 was first released.

Cat 7 liter ( 1500+ lbs) So.... compared to the other pickup Diesel engines, the 6.2 / 6.5 is much less weight.

That's fair feedback, and your notes match mine about weight and intended use. Relative to those engines, it's is fairly light. I was commenting in terms of engines people often use in place of a 6.2L today - LS, SBC mostly. 650 lbs is heavy compared to the options available today. But, those other engines don't make nearly as many good sounds as the 6.5, so add that as a tick in the "pro" column.

We finished it during covid. Made the mistake of installing a Wagler AFO cam. Its super fast but basically acts like a 2-stoke dirt bike with a crazy powerband that hits at 65-70mph, had to buy my son a Silverado SS and I kept the duramax, just sits in my driveway now. I get at least 3 people per week knocking on the door wanting to buy it because it looks bone stock.....when I explain its got $18K in the motor and another $7500 in the trans, they run away.

The 6.5 fueling details are in the next episode, but it's basically a 100gph FASS, big mechanical DB2, and high pressure injectors.
