I must have done something daft, lynall.
Yes, I've replied to your manifold post.

Well many moons a ago a bloke called lynall rebuilt his kawasaki 1100 with wiseco high comp pistons etc etc, went like stink but used shed loads of oil, turns out ham fisted lynall had damaged one of the piston rings when installing them and this then quickly wrecked the bore!
So in answer to your question with manifolds off, if any of the ports inlet/exhaust has engine oil in them you have an idea where to look.
Maybe pop glow plugs out for a look see? but tbh I have often seen dirty engine oil on 200 glow plugs, so assume 300 might be the same?
Have you measured the oil pressure?

But if a bore was wrecked I'd probably have some crank pressure and I don't think I have. And the oil is coming out of the turbo through the IC to be burned. Not passed the piston rings in to the combustion chamber. Or am I not getting what you mean. Sorry mate
Yes, I fitted an oil pressure gauge when I rebuilt the engine. Starts at about 3.5 bar when cold at the moment, obviously drops a bit when it warms up.

A baffling turbo issue. As lynall says I've done something daft and I'm too daft to identify what it is. (lynall didn't say the last bit)
Cold starting pressure is about 3.5 bar

I honestly cannot remember any excess crankcase pressure as it was many moons ago (25 yrs rings a bell) but I was also thinking is there a head issue? ie cracked/dropped valveguide etc, but for a couple of hours work and a new gasket it has to be worth a look?

I've already had the head off investigating this lynall. Had the head tested and valve guides replaced when it was off.

it would be chuffing out of breather and filler cap if it had high crankcase pressureBut if a bore was wrecked I'd probably have some crank pressure and I don't think I have.

On the coldest mornings it possibly gets a bit closer to 4 bar, but drops as it warms up.

Yeah, not doing that.
Just had tea, and munching away thinking reminded me it was the oil control rings i had damaged on the kawasaki.

I'd already checked this possibility about a year before he made the video.

I reckon it is time to stop taking things apart,I'd already checked this possibility about a year before he made the video.
write a list of what the issue is.
write a list of what you have checked.
write a list of ehat you have changed.
and go from there.
Cheers
