I have a 1995 Eagle Summit with a 1.9L Mitsibushi engine that is having rough idle and sputtering. I have oil in the threads on cyl# 1 and did a compression test that showed 190,192,195,195 after putting a little oil in cyl# 1 I got 205,200,205,200. They seem to be in the range per the book. But I am not sure what the problem is rings, head gasket or other.

Think valve cover gasket seeping oil and collecting on plug

Would that allow the oil to get into the cylinder and cause a missfire?

Thanks.

No that could be valve seals or oil rings
