A guy in my other thread found a master rebuild for 550$... how much would a shop charge to do an in-truck rebuild you think?

The guy says it may let loose because of the added boost from the turbo might just push something over thats went bad from no oil, that o therwise wouldn't be an issue w/out the extra boost. The guy ran it for an hour in his parkinglot and said it ran/idled/sounded great.
i doubt it a motor can run a good bit of time with no oil before any MAJOR damage sets in as far as his statement sounds like an umbrella to cover his *** from shitty work

your not going to fix blow by problems with an in truck. ya you found rebuild parts for 550 but thats no labor. no machining to rehone your block and set the new rings and bearings. like i said before your looking around 4K or so probably to do it right by a reputable business.

but thats all the advice im giving on this topic. all my input along with most others that are giving you advice seem to be shrugged off and not being listened to. so good luck

i rebuilt mine with a NEW head for $2,200 including machine work. everyone wants $4-5000 around here too. send it down here. I'll pocket $2000 in labor.

So you think the bottom end needs to be done too? Shittttt I didn't think it'd cost 4g's for a darn rebuild.

You rebuilt it, or a shop rebuilt it? Thats a good price though, 2200$

Me and a john deere tech. mostly me though. there very simple and if you have a good machine shop that knows how to match the rebuild kit to the work they do then its even easier

yes the bottom end would need to be rebuilt too. thats where the blowby is coming from is the piston rings. and whenever you do new rings, you need to rehone the cylinder calls and clean them up
