Do a compression and leakdown tests before you get too nervous, but if you're building enough pressure on the street to blow your dipstick out...I would bet a significant amount of money that it's excessive blowby.
damnit.. whats next
I hope it's nothing serious or major with your motor. How many miles do you have on that built motor?

That's assuming oil comes out of that drivers side breather which I found it doesn't. My hose has no oil in it. If oil did come out of the drivers side breather then now it would still come out but go all over the engine compartment wit hthe breather installed.
What Doug did does nothing. The problem is.. I'll say it again because no one is listening to me or Sharif.... under boost there is not enough cranckcase evac with the OEM PCV system operating. There are 3 or more threads on this now.

While that may be true, the problems that Sharif has experienced have manifested themselves during hard track sessions, not just getting on the gas for a few seconds on the street. Doug's car is blowing the freaking dipstick out...that's some MAJOR pressure to do that.
i switched it back to the left side now
yeah from the hose on the bottom of the upper plenum when i disconnected it..

Doug, since you put it in the right spot....go drive it and get into boost a couple times and see if it blows out again. It might not have even been all the way in the way that pep boys put it....

Hopefully it's just that the dipstick was installed wrong before.

I say start with the basics guys.
I am not running a catchcan setup (yet, will be after cams are installed this winter. Bigger cams = less vacuum in general).
I just have a breather filter under hood.
And I run MUCH more boost than most on here (the turbos like it and can produce it), and I have NO blowby issues at this level. Now there is always some blowby, thats inherit. But even with the breather I have zero oil blowing around under the hood.
I agree Sharif's situation is not the norm. On the track he's probably never below 4K rpm, and always in full boost. So his will show the worst possible situation it could be.

Does anyone have an actual answer ? I have a turbonetics single... I seem to be burning alot of oil, could be because of piping... but when I installed the plenum spacer ( a while back) I noticed some oil in the plenum. I have already installed the catch can on the passenger side and it seems to be doing perfect, it collected about a teaspoon of oil in 2 days of driving. My question is, will I benefit more from installing a catch can or a breather filter, on the drivers side?

That all said my car does consume oil at a more rapid rate than it did N/A. It did it with my stock motor and the APS kit and it does it the same with my built motor and the APS kit. Most aftermarket turbo kits cause you to consume more oil, it seeps through the turbo seals and into the exhaust where it's vaporized, not burned making a sweet smell, not the classic burning oil smell.
Does your exhaust smell sweet or like burnt oil?? Sweet is just the turbo seals seeping. Burnt oil would indicate that a significant amount of oil is entering the combustion chambers either by the rings or through the valve seats.

Real cars and race cars burn and drip oil
