So i didnt get a wink of sleep last night worrying about swapping engines and the like.
Went to do the valve adjustments tonight and went to take the ht leads out. #1 provided no resistance. it wasnt seated on the plug properly and the little nipple thing at the top of the plug was loose. all put back together properly for a quick test and the knocking is totally gone...
Time to swap out the super 4s for ngk i think!
Thanks for all the help guys. gonna do the valve adjustment at some point anyway now i know how to do it, and this whole incident has scared me enough that im gonna look into getting my oil leaks sorted!
