Hello all last night dropping my friend off did some spirited driving and as soon as I stopped I got a oil smell coming from the car.

Only thing I have done differently last night from since I got the car was I upped the boost to 20psi from 21psi

I have the following mods done

39k miles on the motor and oem turbo

HKS 264 cams
Map open o2 dump(sounds great at wot)
HKS intake
10.5 hotside
Perrin Catback
Halman MBC
255 pump
Hawk pads
Greddy RS bov

Compression is
175
170
180
185


I'm gonna assume this is a crankcase vent issue or tune issue I could not see if the car was smoking as it was raining.

Any insight would be great

Thanks

 

I would first check for simple things, such as crankcase vents/piping/hoses (however you have it set up).

Any noticeable leaks?

 

Are your PCV's venting to atmosphere or oem routes? Other than double checking the PCV's are not clogged etc..

Did you check the turbo for any play? Also, any oil in intake that may have leaked from the turbo?

 

I have not checked any yet after work I may take off the intake and check it out for shaft play, oil, ect.


The PCV looks like a oem setup

Nothing is leaking under the car.

 

So this is still a problem but now everytime I boost all I smell is oil @ 24psi. I'm gonna take out my PVC today after work and check it . If I buy a catch can it must be a duel inlet with a breather correct? It would be hooked up to both ends to the valve cover and plug the intake ?

 

are you sure your not smelling the open dump? you should probably stop just upping boost

 

As far as the catch can, Yea, I plan on the same type setup

 

the hose kept poping off the intake no problems now. The boost got turned up since I got tuned
