Spark plugs are black again

[silviaz]

Oh boy here we go again it just doesn't end haha. So I went to take out the spark plugs to see the condition of them and checked the compression of only 2 cylinders and they were perfectly even. But noticed both spark plugs especially the first one was quite dark, seems like it's running rich. Even the exhaust tip is black. When I went for a drive today the smoke was very light grey or white and dissapeared fast it seems to appear on high revs or switching gears on high revs? and in 1 instance the smoke was black somewhat. Here are some photos: No idea what it is,  I don't think it's piston rings or bent valves considering the compression was the same / wasn't a big difference.

Rub the exhaust tip with your finger. If it's oily you're burning oil, not running rich.

I rubbed the exhaust tip and my fingers and it wasnt really oil my finger was quite tight rubbing against the exhaust tip. But it does look shiny, here is a picture

That’s a very nice photo. Based on that entirely you should pull your engine out and put it in the bin, replace with an Ls motor of your choice

If it felt even the slightest bit wet/slick it's oil. Otherwise that's probably soot from running rich.

I would also confirm against the plugs. Running rich will turn the plugs black but it should be a dry deposit, not a wet one.

That would make sense I guess. So on the tip of the exhaust my fingers shouldn't be rubbing smoothly if its running rich only right?

Im with Ben. LSA would be my choice.

I just checked all my cylinders have oil inside them it seems. I do remember a while back when I took off the intake manifold there was some watery stuff like oil inside not sure if that matters? Check the picture here there was liquid in here
