I got the intake manifold back from being ceramic coated, very nice. Pushrods on the other hand, no one’s getting back to me…:rolleyes:
Tried a comp test, no intake on and stone cold. Only did three pumps, don’t want to burn the starter bushes. ( done that in the past ) - 155-160psi. Looking good.
So from 210 - 220 psi to 155 - 160 psi as a result setting the lifters properly. Looks like in your case hydraulic lifter bleed down can significantly affect cranking compression.
