hi all, have an issue with port motor, moisture on #4 & #6 plugs.
NOT enough to impede 5500 rpms but any moisture isn't good.
swapped heads, gaskets and am still seeing moisture on plugs.
compression checks out.
is it more probable to have exhaust cover plate issue, exhaust guide issue, and if either are common are there ways to check if it's one or the other ?
also, if it's exhaust cover are there any tricks to not break all bolts...heat, etc ??
thanks in advance
