Like the title says found a 38r on craigslist for $600 bucks. My buddys in need of a turbo so were gonna go check it out wondering what to check besides shaft play. Heres the link if you guys could help thatd be great thanks.
Inspect the compressor wheel for dings and nicks. Looks like he used a 6637 filter so it should be ok. Do check for in and out play. It will have a little up and down play. Thats a good price. Make sure you get the intake boot for it.
The only issue i see is if the oil ring did blow that the turbo didnt get oil and burnt up an oil seal on the inside of the turbo. Hopefully theres no shaft play and the bearings feel okay.
No it was supposedly the o ring on the pedestal. My concern would be if it was pissing out the o ring not allowing oil to get to the turbo running the turbo dry of oil making the seals in the turbo messed up
If it was puking oil out bad enough to starve turbo I would guess the motor would not run long enough to cause damage. I personally dont think its worth the risk.
Do any of you guys know what a turbo seal looks like?
The condition described in the ad is caused by too much oil at the turbo shaft. High crankcase pressure slows the oil draining from the turbo. When the cavity gets full of oil the crankcase pressure pushes some of it past the sealing rings.
No lol i actually dont but sounds like you hit the nail on the head! So the oil would leak past the turbo oil seal before the o ring on the pedestal correct?
You have two o rings in between the turbo the pedestal. One for the feed oil and the others a return line. The ones in the pedestal rarely blow out cause they have no where to go.
Oh just re-read it idk why i thought he said the pedestal o ring. He said the turbo oil seals so its no good??? Gotta bear with me my add's kickin in haha
The turbo shaft seals are not positive seals. They are metal rings similar to piston rings. They depend on oil draining away from them to prevent them from leaking. If they are standing in pressurized oil they will leak.
I don't know if that turbo is any good or not. But it is possible for it to be good and leak under the condition described.
