Oil Out Exhaust

[mr_rbman]

hey guys, the last couple of times i've started my car up its spat oil out the exhaust and left crap all over my driveway. (doesn't happen everytime though)

Now the turbo is only approximately 5000kms old and doesn't smoke at all when i drive so i'm presuming/hoping its not the turbo. (could be better than the motor though)

I finally had time to hop under the car yesterday and it appears to have oil drops over/under the cat converter so it look to be getting a bit of oil into the exhaust.

The motor is approximately 4000kms old and is a RB30DET, the only other thing i could think of was that it was possibly compression or something related but the car still feels great.

The things i have done recently to the car is spark plugs, cam gears and played around with my catch can, the only thing out of them 3 that i thought could cause this oil problem would be the catch can but i don't know what i could've done to cause it?

Any ideas on what it is would be much appreciated!

Who built the motor?

if you had oil in your exhaust you would know about it, it would burning the oil while you drive and smoking like a mofo, take a closer look its probably really dirty water, just some condensation, my GTIR used to do the same thing, stains all over the driveway

mmmm, i've smelt the substance though thats coming from the cat converter and it definitely smells like oil.

The other couple of things i forgot to mention was that i'd recently taken my BOV off (can't see how this would effect it though) so that i have nothing and I never get oil in my catch can, Its one of them cheap ones that have nothing in them and just a couple of holes with a filter on top if that makes a difference.

I also took my piping from the throttle to turbo off and there's no traces of oil in them!

On a side note i also get oil leaking from between the gearbox and motor, would that be the rear main seal thats gone?

The oil from the cat, would be from between the gearbox and motor.

What you're probably spitting is condensation, and carbon build up. It comes out VERY black, and filthy and stains like a mofo!

Get someone to start the car after a humid day, followed by a cold night, while you have your hand over the tail pipe (Let the gas get out though!) and you'll find it to be carbon most likely built up in the exhaust.

ok, this seems to be the consensus from most people which is a good thing, just wierd that in the 2 years i've had the car its only just started doing it!
