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

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?

    • To clarify, I meant nismo bushes, not control arms (don't even think that's a thing for my car). So the suspension specialist said, if I buy those nismo bushes which are perfectly centered it will cause my car to veer in one direction. Whereas he said the current offset bushes that I have were put in on purpose to fix that issue. This will be my third wheel alignment if I put these bushes in lol. My chassis is straight, all my rails are clean.
    • OK, well, in that case, the suspension specialist is either a moron, or you aren't understanding what he was trying to tell you. Nismo arms are not really different than stock arms. Both are fixed geometry. I don't know if the Nismo ones are a little shorter than the stockers (or perhaps even a little longer) or the same length, but....if you swap from stock to Nismo, whatever happens to one side will happen to the other side. It will not cause it to steer left or right. That is unless you have adjustable bushes in your stockers, and they happen to be adjusted to dial out some bent chassis shenanigans. But, if that were the case, you'd just put adjustables in the Nismo arms anyway, because Nismo arms are essentially just expensive stock arms. And doing a wheel alignment is just a weekly thing in my world. I have had the suspension apart so many times this year that I've lost count and just about worn out a torque wrench. I'm out in the shed right now cutting up some alloy section and making bases for my new stringline setup. Got to make new swivel plates next, then I'm good to do toe properly, as well as camber and bump steer.
    • Yeah, nah. Not a thing. The gasket between the top of the plenum and the runners is far more likely to blow out when it gets old, and not really at ~14 psi. These things have been run to double that for 30 years without that being a common thing.
    • I plan to pull the intake manifold off and check the gaskets, i read that the block to manifold gasket can blow over 14psi and when i picked up the car it was set to 1.2bar on the controller. Send the injectors out for cleaning. Ill also pull the cam covers off and do an inspection, check some valve lash. Someone also said that the timing belt can rub or vibrate against the belt cover and make that sound. Definitely need to get an AFR gauge on it, if it was lean idling im sure it wont be happy
