[Healeys] knock

[David Nock]

Not likely the crank pulley will usually make a klunking noise at idle and 
oil pressure will not make a diffenence.

A little off the wall but, have you checked the front pulley nut for
tightness?

before i tear my engine down i am going out one more time to see if anyone
has ever encountered this condition before and
the remedy.  after about 500 miles on rebuilt engine detected a knock near
front of engine.  two conditions have to be met
for this knock to occur.  engine oil must be hot and it must have set for
10-20 minutes.  will not knock on cold engine or
upon immediate restart.  knock ceases immediatly when oil pressure builds
have plastigaged rods and the two middle main
bearings.  have checked all new lifters, pushrods and valve train.
installed a new timing chain tensioner and damper.  oil
pump about 5 years old.   have had piston slap and wrist pin suggested as
culprit.  any ideas?
