strange sound in engine

[paul cass]

thanks brent and larry
the engine has an electric fuel pump. as much as i hate the idea of disassembling the engine i guess that will be the next step. the intake plenum covers the right side valve cover. typical. guess we'll start with removing the intake so we can look at the valve train. if anyone else has any ideas, give me a holler.
thanks,
paul

I would recommend picking up or borrowing a device I've used in the past. Basically, it is a cheap doctors stethascope (sp) with the listen end taken off and a hollow , thin copper rod braze or slipped into the single tube line in it's place , about 2 feet long, The idea is to place it on the block, near suspected areas to listen for source of noise. Bearing or wrist pin issues are easy to hear as you rev the engine. Can also be done with an old fashioned 2 plus foot long screwdriver with a wooded handle...tip on block, ear on handle.

Hey Paul, I'd check the header gasket first. If you could spring the header/exhaust manifold out far enough from the head to see if there's any signs of exhaust leaking. It will be obvious.
