I need to look into spark plug holes again, and all of them this time. Last time there was some oil in 1-2 of them, but not much, I just cleaned it. Can oil actually get into the cylinder and foul spark plug? I mean spark plug is torqued, so how would the oil get in there past the spark plug thread which is kinda long and tightened....

I say this because I get bad vibrations and rpm floats on cold start and then after drive it becomes almost smooth and rpm rock steady, every time I drive from cold start.
Almost as if something either burns off or warms up or lubricates I don't know.

I will check oil filter too and both Vanos solenoids will get replaced soon (one has fluctuation).
