Default Oil smoke from exhaust.....damn.

Well....as the title states...my car has been helping fog for misquitos lately. It randomly happens when I come to a stop while idling. I cannot induce it nor do I know the circumstance to replicate it. But it does seem to always happen when there is a nice car next to me when driving in downtown Atlanta. Probably happened about a dozen times in the past 3 weeks.
I pulled the dipstick with the car running to check for excessive crankcase pressure and found none. Pulled the intake pipe by the TB and found no oil/residue in the intake, on the TB or in the intake manifold (IM was actually VERY clean and free of soot/buildup). No oil dripping out of the intake filter, some very light oil residue on the bell of the BOV (I assume this to be faily normal for a car that is driven at WOT a lot per oil vapor from the breather line).

After talking to a friend, the first thing he asked was if I had a oil restrictor. Nope....sure don't. About 70k on the turbo with no restrictor. So I located one at a local speed shop. Told the owner what all was happening and he was quite surprised to hear the turbo hadn't blown a seal a long time ago due to no restrictor (the shop is Top Speed and given they built a mega Subaru GC8 to compete in the Redline Time Attack series and stomped the competition in unlimited AWD...I'm sure they know what they're talking about). So tonight I put the restrictor in, loaded up a older map (car has been running funny with the warm temps) and fixed my water pump/alt. belt that was squeaking. Took the car around the block and it seems to feel/smell better...but I'll reserve any final verdict until I've done about a week of driving. I hope it's fixed, if not I guess I'll be looking into buying a new turbo before this one gets too bad... :(

Yeah, pointless thread...but I just felt like posting something. Oh, I was thinking about adding a catch can, but after seeing how clean the IM was, I don't think it's needed.

When I read the tittle of your post I was 99% sure you had the same problem as vash and after reading your post I was right...I don't understand why Garrett wouldn't just make a restrictor already on the turbo

...and if this is such a known issue, I'm surprised FM has not addressed it either

Isn't that the way it always works out?

My car is invariably running shitty for one reason or another every time I get a decent challenge from a car I'd normally walk on. Why me??? All that work, only to be embarrassed.


I was scared when I read thread title, I hope it is as simple as a restrictor.
