I just changed all my rockers, arms and pushrods. Well, this isn't the weird part, but it took me about 15 minutes and 105mph to finally get the rockers to seat and stop knocking, but get this. Completely random, and very very few and far between, one knocker goes knock once and you won't here for a longggg time. I mean I can deal with it no problem, it actually sound like a rock hitting the bottom of your car. But, why do you guys think that its doing this. The cars running gurrreat so I'm not worried.....Anyway, later.....
