Oil In Intake Pipe And Over Throttle Butterfly!

[R32 GTS4 4DOOR]

Hey guys and girls

Today i took my intake pipe off my car to replace my noisy BOV with the standard silent BOV, and as everyone does, i looked around to see if there was anything happening that shouldn't be.

I noticed there was some oil sitting on the bottom of the pipe and over the throttle butterfly!

Question?? What is happening?? i think it could be the gasket has gone on the turbo? or could it be sucking oil out of the engine via the vacumn line from over head the coil pack cover?

Cheers everyone who tries to help and has helped in the past.

wow, mine wasn't that bad!!!

could the oil that is passing through be affecting the performance of the car??

[gfunkk]

kind of but not really

ive been told it lowers your octane level a little

but yeah i still dont like the idea of my pipes coated in oil

i went to markets n bought a cheep shitty oil catch can, then found some old heater hose,

i cut where the blowby pipe thing goes to the intake and put a bolt in the hose, then put the heater hose on the rocker cover thing down to my catch can thats cable tied to my battery

either high oil pressure which puts it through the inlet manifold to get burnt of,

or either coming up past the rings..

aka blow back buddy

ok, all good then. i'm not getting any blue or white smoke so all should be ok. ill invest in a catch can soon. :-)

Someone tell me if im wrong. But is that due to your PCV valve being faulty?

[bubba]

*could* be one of many reasons..

Mostly likely is tired engine with excessive blowby.

pcv valve closes under boost to stop the crankcase being pressurised

wat is a pcv valve??

[R33_NICK]

think da pcv valve brings blowby gasses back to the intake manifold 2 b burned off completely. was learning bout it at TAFE last year but correct me if im wrong cuz i cant really remember. it doesnt affect the performance much but letting only fresh air into the intake manifold is always a good thingbut id check to see if its something else dats bringing oil into the intake pipe but most of the time its excessive blowby.

Positive Crankcase Ventilation

Very good read

Something Holden engineers should have done a better job of with the old 308

Which is why they always seem to have oil leaks-even not long after new sump gaskets are installed
