I changed the main gasket and the two spark plug tube gaskets.
That's why my motor is making me nervous. Both of mine went up at about the same time somehow, along with the plug seals. I know plugs boots 1,2, and 3 all had oil on them, forgot about 4 haha ( and inside tubes aswell). I feel like there's another internal leak somewhere.
Huge coincidence or underlying leak?
At first I thought it was from the recent timing belt/water pump/thermostat job but I was told on here, that valve covers don't have to come off for that.
