[FWDLK] Engine Knock

Hi all.

Earlier this month I asked the List for their opinions on a nasty engine knock that I was experiencing in my newly rebuilt 57 Fury 318 engine.

Thanks to the List I received a huge amount of suggestions.

Any one of these suggestions could have been correct.

So what was the mystery knock...?

Turned out that there was insufficient clearance between the bottom of the piston skirt and the crankshaft counterweight, so that they were just making contact as the two met at their closest point, when the piston was at the bottom of it's stroke. My engine rebuilder machined a minimum amount off the counterweight, and I have since sent the components to an engine balancer for balancing.

With any luck I should have a smooth quiet engine again in a couple of weeks.

I cannot thank you guys enough for all the responses.

This is a truly great List!!!

(I tried to include all the actual responses in a previous email, but as there were 23 of them, the FWDLK List rejected the email because it was too long-over 760 lines!)

Glenn Barratt,

57 Fury.
