Default Re: Engine rattles

When people don't put a good coat of grease on the cam plunger, it will squeak for quite a while. I started an engine that someone else rebuilt, and I did several short runs to warm it up and let it cool down. After about a couple hours run time the squeak finally quit. I like to put a coat of Mystik JT-6 High Temp grease all over the timing gears, plunger, and cam lobes.

Who rebuilt the engine, and can you pinpoint the rattle to some part of the engine by using a stethoscope? Loose rods and loose pistons can rattle. I'd assume a rebuilt engine doesn't have a two piece timing gear with a loose aluminum center.
