about 4000 mi ago i got new seals put in my turbo since it was out. they looked at it and cleaned it up and since it was apart they put in a new oil seal. all for 175 bucks. it started blowing oil out the exhaust side giving that fryed oil smell but only when you come to a stop and let it idle. when running down the road it clears up.
i asked them and they said sorry about your bad luck we only warente rebuilds and they are wandering when the next one will leak from blowbye. that is what they are blameing it on is old engine with blow bye. well i would guess it would get worse at speed running boost past the rings.
the things i seen are the oil drain was not near the 15deg max from strait up and down. and i think the oil seal ring had the gap on the bottom. my GOD i paid someone 175 bucks for less than 1 hour of work for thier knowledge.
anyone have this happen to thier turbo?

if they replaced the bearing, in theory it should not leak. hmmm. The turbo would leak more oil while you were giving it, if it was blowby...

they did not touch the bearings as far as i know. the only oil seal i see is the ring on the turbin side i am looking at the brass bearing on the comp side.
it is a air reserch from a 83 td quantium. i think it was more responcive than the garret i have on now. but i have been driving my dodge diesel so my opinion is jaded a bit. the garret is much quieter than the air reaesch and seems to make the same power. i wish i put a boost guage in. it looks like bearing clearence and comp wheel keep the oil from comming out the compresser side. the thrust is ok.

there are no rings on the compressor side of the shaft so the other ring must be in the bearing i hope.
i will learn to post pictures and put them on. i am betting on the drain was not rotated as far as it could of been cause there is nothing wrong with the oil ring on the turbine side.
i am going to look for the compresser seal tonight.

i can just bolt on the compresser side they balanced it neutral and it does not matter so i am hooked.

I've read online that a lot of drag racers are looking at getting oil pumps to help pump the oil out of the turbo to reduce the pressure in the turbo. Which is probably because the addition of the turbo required it to be installed in a position where the oil drain wasn't totally vertical.

I would say blow out all of the turbo lines just to be sure.

i am going to blame it on the turbo shop did not have it rotated enough when assembling to get the return line up as close to its old position. which caused kinks in my return hose i made. but i wonder why it took about 3000 mi or so for this to happen.
