GTO5005 Posted April 21, 2018 Share Posted April 21, 2018 30000 miles ago I replaced my turbo with a brand new VF52, I have just noticed about 3000 miles ago I am going threw a quart of oil about every 200 miles. I removed the screen from the banjo bolt also when I put in the new VF 52 turbo. I have car apart and found large oil dripping from under the turbo coming from the turbo inlet into the turbo and dripping down and touching everthing in its path to the ground. I threw code P0021 when I was 2 and half quarts low. Thought maybe OCV? PCV has never been changed, car has 91000 miles on it and this motor has about 57,000 on it. Running 17.5 to 18 lbs of boost give or take. My ringlands bad? Turbo seal maybe? Would removing the screen from the banjo cause that much extra flow for a large oil buildup under the turbo? Car is apart with turbo off. Do I need to put back together for a compression check? And if so can a link be sent to me so I can do this correctly please. Was unable to find it when searching. Ty for all input. No power loss,no shaft play. Link to comment Share on other sites More sharing options...

Infosecdad Posted April 21, 2018 Share Posted April 21, 2018 Check your PCV, sounds like it is clogged (among other possible things) Link to comment Share on other sites More sharing options...
GTO5005 Posted April 21, 2018 Author Share Posted April 21, 2018 Have a new one gonna do that also, just hate to throw it all back together and find out that the turbo has a seal leak. Link to comment Share on other sites More sharing options...
relative4 Posted April 21, 2018 Share Posted April 21, 2018 Is the inlet damaged at all? Link to comment Share on other sites More sharing options...

MaasaiWarrior Posted April 22, 2018 Share Posted April 22, 2018 The little hose from the block to the pcv is probably split, I had huge oil loss issues until I found that problem. You need like 2" of fuel/oil rated hose, a local speed shop gave it to me free. 08 Spec B, insta: @08_spec_b, 10 SH Forester insta: @shfozzy Link to comment Share on other sites More sharing options...
GTO5005 Posted April 22, 2018 Author Share Posted April 22, 2018 This hose is part of my new PCV assembly. Hose there looks fine, the oil is either coming out of the turbo in front of the turbo inlet where they meet or I have a engine problem. I do see slight oil inside turbo on either end.

GTO5005 Posted April 29, 2018 Author Share Posted April 29, 2018 Okay so your saying also turbo seal going bad? If so these turbos just do not hold up. Link to comment Share on other sites More sharing options...
Marvick08GT Posted April 30, 2018 Share Posted April 30, 2018 No, he's saying that the oil is entering your inlet BEFORE it gets to the turbo ( pcv, clogged or broken hoses etc) Link to comment Share on other sites More sharing options...
GTO5005 Posted May 2, 2018 Author Share Posted May 2, 2018 Okay, well replaced the pcv and oil control valve, and it's a 50 50 split on where the oil is coming from PM's and public posts. Ty for all input. Link to comment Share on other sites More sharing options...
