Re: Simple diagnostic: pull the lower oil pan, and >>
Well, the chain would be slapping due to lack of tension. The lack of tension could be due to either extreme tensioner pad wear, missing pieces of tensioner pad, or a weak tensioner. I guess it's more the case of the weak tensioner "early failure" that I'm concerned about (without having to pull the oil pan).
I guess it's unmistakable, then, when it's chain slap? It can't be confused with VANOS knock or HLA ticking?
