<DIV>first a thks to those who did respond to my problem: a loud clatter
from the right rear of my cylinder head.</DIV>
<DIV>following advice I have done the following:</DIV>
<DIV>Listened through a hose to isolate the noise: Definelty #6 exhaust
valve. Hose against the exhaust manifold loud clatter; against the block,
it will make you deaf! Other valves are very quiet with similar
test. Other side is quiet.</DIV>
<DIV>Compression: #6 was highest of all at 145 lbs. Rest were
135-140.</DIV>
<DIV>visual inspection: nothing broken, all working OK</DIV>
<DIV>Valve gap: all OK </DIV>
<DIV>Suggestions have been loose seat, blown exhaust gasket, bad pushrod, bad
lifter.</DIV>
<DIV>Valve gap being OK pretty much rules out the bad seat, quiet on left side
of head and block rules out lifter and pushrod.</DIV>
<DIV>Leaves gasket, but the noise seems isolated, and really loud and
metallic from the head itself and the manifold right at #6 exhaust only.</DIV>
<DIV>Thoughts, please.</DIV>
<DIV> </DIV>
<DIV>Please respond to me direct, too, I am on digest version.</DIV>
