After searching the forum I could not find a post to cover this specifically...
I have oil fouling on left spark plug and if I hold my hand behind left exhaust oil residue on hand, but the exhaust does not smoke. Right plug and exhaust no oil.
I did a compression test and need help evaluating the results...
Engine warmed up approximately 45 minutes before test so almost cold at test
-Dry compression test left jug 160 / right jug 175
-Wet compression test left jug 200 / right jug 200
Is there enough difference between the dry vs. wet test to call this a ring problem producing the oil fouling on spark plug, or do I possibly have a valve guide that is worn and that’s where the oil is coming from?
Thanks in advance.
