I have been smelling burning oil over the last 2 weeks and decided to do some investigation. Here are the pictures, was wondering if this is common or if I have a blow-by problem developing. My first guess is that the plug seals are just not working correctly, but the worst pooling is around #7 plug. #1 is leaking a slight amount, #3 & #5 are clear.

Anybody have some insight?

PS how do you attach a picture?
