I has boost, :O)
I have figured it out but this is more of an info post for you guys to avoid this crap in the future. This has cost me $1000's.
Customer has his 96 Dually, auto 6.5 turbo towed in, made a bang and stopped working, engine siezed. I yank the engine, it ripped out 4 main webs and broke the crank in 3 places, ):h
Had a local machine shop redo the engine, nothing was usable except cam so he got a new block and heads out of Ontario, local supplier stocks them, did some searching and no problems found and other shops had used them with no problems. Got it together and first problem was I stripped out the motor mount pads?????????? turned out they were tapped for metric so I redid them in 3/8 course, like the factory block.
Put the engine in, everything seemed fine but after it warmed up, no oil pressure at idle??????? put a real gauge on, verified zero warm at idle, 20 just above idle??? We do some messing around and he didn't know about the oil cooler bypass and plug-no instructions with the block and the other one was long gone, I guess that's 2 bad omens, put those in, still no better. Yank the engine and he tears it down. Can't find any issues but bearings damaged, turn crank, then I find out about the 98 and up pumps having more volume, makes sense as 900 rpm, have oil pressure, 750, none. So now we find this is a 98 and up spec block so we should have used that pump to begin with, :mad2::mad2::mad2:
Wheeling it over to the machine shop, it almost fell off the stand, seems they tapped the bellhousing bolts also metric, so had to helicoil all of those too, :mad2::mad2::mad2:
Put the engine back together and back in, fire it up, now I've got like 75 cold, yay. Get it all done, and again as it warms up, oil pressure starts to drop, I get home and its just above 0, :sad:
Bring it back, rip out the engine again and now using a stock repaired block, I should have it running tomorrow. In the mean time, we found another shop who USED to use those blocks and had the same issues we did.
As an added bonus, his 7 month old IP shit the bed coming to work so I had to get towed in, :sad:
I'lll update as it goes.
