Leaking Exhaust Oil!

[boomtheroom]

noticed oil commong from the exhaust manifold by the first exit closest to the front of the car ,thinking rings what u guys think,blows a little blue smoke at idle every now and then ,not much on boost?

[mad082]

first see if there is any oil above the manifold.

may be a rocker cover gasket. pretty common. or the oil feed posibly?

[boomtheroom]

nope none above the manifold ,rocker gaskets are new not a drop from that area ,just from that exhaust outlet.can thing of anything else that will let oil out in that area but the pistons,please prove me wrong with another theory!

[boomtheroom]

heres a closer pic

[mad082]

doesn't look good.

did you remove the manifold stud, or is it broken?

[boomtheroom]

nah stud has never been there :-<

Exhaust valve seal gone? it would leak into that area

I have the same thing. It appears to be leaking oil from a broken/missing stud. A friend pointed out some oil from my rocker gasket and suggested that it's just running down the back, and then around that last manifold pipe.

I dunno.. I recken i've got a tiny leak there, but my pressure and temps are fine, and it doesn't lose oil.

I HAVE heard that if you drill too far into the hole to get a broken stud out, that you can go too far and puncture into the head fairly easily. Either way, with a new stud in there, it should seal that hole up pretty well I think!

Hopefully i'll be getting all new studs in the next few weeks.

whats the easiest way of finding out ?? if it was leaking that much oil through the piston rings what other symptoms would there b?

i took out 2 of the closest sparkplugs near the area do they tell any tales?

would leakin valve seals affect the power much?

Does your car chew up oil? could be your piston rings are gone-ski and to make things worse, some of your exhaust is leaking out from area with the missing bolt...

Looks like that spark plug has been burning oil.

just did a compression test 1-6 in order were 132,134,134,112,130,132 did a wet test on cylinder 4 and got 170psi

what u think?

[Dose Pipe Sutututu]

Your piston rings are worn. Get them changed for all cylinders, and while your at it might as well whack on a better head gasket for some serious boost later on.

hmm well thats not good i had that on mine and yes, at that stage i had completely stuffed four pistons
