So I'm just took out my spark plugs and every single spark plug is good besides cylinder 4 spark plug.
Do you guys have any guesses what the main culprit is? Been having oil leak problem for a while, even though it hasn't leaked in a month from what I've seen it's been on average .5L a week to two weeks lost. Also Mechanic did testing on my PCV and the testing came out good so not sure what it could be. |

Guess I'm going to start with a valve cover gasket, even though my PCV testing came out fine. Do you guys recommend replacing the valve cover too?
Also, is there any DIYs I can use from N55 or N54 to replace this? None on B58s I can find and not really trying to pay a grand or more unless I have to. |

There was some oil inside on the left side deep inside near where the spark plug goes inside. Besides that, was relatively clean everywhere else that I saw including when swapping the plugs out.

Just wondering. I had a similar issue on my N54, and it was from me spilling oil when refilling which ran into the one plug bore.

Do a compression test on cylinder 4.

I thought I was going crazy because I couldn't see oil on the tips but I made an assumption
