I recently looked at the comp housing and I notice oil spread inside the housing in a spiral fashion.. Does this mean I need a new turbo??? ITs pretty new garret t70, I bought it a while ago but it has less than 100 miles..

 

anyone??

 

Check oil drain, no kinks, smooth bends, .5" bare minimum. Make sure you have adaquate BOV, PCV. I would look at those things first. If you mean it is excessive or way more than a film then you may need to look at the turbo.

-S-

 

my turbo surges like a bitch... I opnly have 1 type s and it doesnt even sound good anymore... but why would oil be in the front cover when I dont have my breathers connected anything? its not on the pipes either, only on the comp housing...

 

martin how do you know this is happening....what does this sound like? does it happen on boost? or off boost?

 

Well I know what surge is... and it happens mostly when im off boost... I feel like adding another BOV... It also surges like crazy when Im about to go to positive and then I release the throttle a bit...

 

ok but what does it sound like...just wanna make sure i'm not experiencing the same thing....heard about compressor surge but no one has explained the tell tale signs

 

it sounds like surge... the word explains the sound... its like a wave of air going back and forth... another word that I can use to describe it is flutter..

 

ok thanks for that. i have a MP t70 so thats why i was wondering. and it happens off boost?....at what sort of revs and speed?....could it be restriction on your system...ie hotside or exhaust?.....do you have a straight through midpipe?
