Subject:      odd noise on new gowesty engine
Content-type: text/plain; charset=ISO-8859-1; format=flowed

Guys,

I have roughly 500 + miles on a new GoWesty 2.2 engine that I just
installed and am curious about an odd noise it makes, but only when it
is warm, eg been brought up to temp. On startup, ie cranking, just
before it starts and when turning of the engine there is a small clunk
noise. Almost as if before and after  ignition takes place a compression
sound as the engine comes to a stop. The engine runs fine and there are
no odd noises while running only at start and stop. I have not been able
to listen to it back at the engine compartment yet but am planning to do
so. Nothing is loose that can explain this and maybe it is a normal
sound and is compression on these engines? Oddly it only exhibits this
noise when hot though. Could it be a loose head? Sticking valve?

Logically I am being very careful to break it in properly and am
listening and watching its behavior carefully and want to ensure that
this is not something that is going to end up being an issue down the road.

Any ideas ?
