Engine Noise! knocking...

[importdude]

its making a knocking noise. sounds like rod knock! but is not? absolutly no power loss!. it sounds like its coming from the head!


Replaced timing tensioners, guides, lower chain, new timing cover/oil pump. Still making the dam knocking noise

ALL BEARINGS IN SPEC (plasti guaged it all and no scoring on crank journals



will shoot some cash to someone that helps me pinpoint this stupid sound/problem.

Valves clearance will be checked tomarrow. Cams are going to be removed also to check for buckets

Valve clearances

Intake Side .014 .014 .013 .015 .013. .016 .013 .014
Exhaust Side .014 .014 .014 .014 .015. .014 .016 .016

shims/buckets look fine

*noise is not always there" sometimes it stops then makes a high pitch grind/squeel"
if it was knocking it would be 100% knocking all time
