Oil In Cylinder

[KerrodR33]

I have a mate who just recently purchased a 33 and upon pulling the crappy eBay turbo off to replace with a standard unit he noticed some broken manifold studs and lots of oil build up around the exhaust flange and cylinder.

He sent me a picture but I am unable to work out what it could be.

He has a breather setup that is spraying oil everywhere which he is going to replace with a catch can. So I am unsure whether its just oil spray from that or if he has worn valve stems or something else.

What do you guys think it could be?

I would guess that cylinder is screwed. cracked ring lands more than likely.

Could do a comp and leak down test , but what does he want to achieve, it won't be an easy fix.

Does it smoke?

Might as well just drive it and plan on an engine swap soon.

Ok ill let him know next time I talk to him.

Might be in for a bit of butt hurt as he has just moved to Australia and this is his first skyline.

I think his plans are to mildly modify it to a decent standard so best bet would be for him to replace the motor as it looks really tired.

He said it was smoking a bit today but I told him it would be due to the breather on the pcv throwing oil up.

Its not the head drain gasket is it? Looks a bit to widely spread to be from there but I'd check it just in case

Yea might be worth a shot to look but judging from the pics it doesn't seem to be coming from that area.

It looks as if its coming from above which is why I suggested to him it could just be from his excessive blow by out the breather, however on second look it could be getting blown out the cylinder and leaking out past the gasket due to broken manifold stud not sealing properly, which is why there is also oil on the inside of the manifold.

We both live in Darwin so reputable mechanics are stretched far and thin and I have always done work on my own car due to this, so I wouldn't be able to suggest anyone to take it too for a proper analysis.

Actually yes. Didn't see it was inside the exhaust ports as well.... Looks quite a bit like oil past rings....

Simple comp and lesk test will tell u.
