Hi,
I'm not a professional mechanic and have no idea what is normal inside the engine and what is not. I checked recently what is inside the valve cover of my Civic simply looking through the oil fill hole and noticed some dirt/sludge on the rocker arm/spring/what is it called?
Do you guys think it is normal or are there some issues with the oil? I'm doing roughly 4K miles OCI. There was Mobil 1 0w30 ESP LV and then Castrol 0w30 A3/B4 European oil. The car is ~20K miles.
Thanks!
