1944 with rattling sound

Hello
I have just bougth myself a 1944 Willys. It is a norwegian car with a few mods from the millitary. There is a curtain in front, and a heater mounted underneath the dashboard. Nice and original car.

I am also able to read the name "little willy" that have sometime in the past been written on the panel below the windscreen. It is not a panel restored car, so i would like to belive that the text has been there for some years... :wink: The engine is restored sometime ago, but i do not know much about this job.

Well, the downside is that I have a rattling sound in the engine. It appeared suddenly, and the sound follows the revs. The oilpressure is good, and so are the power of the engine. I wonder...could it be a loose valve guide?? The engine was running perfectly before this sound appeared. The car has been parked for some time, so i was very careful when i started using it...but obviously not careful enough...

Any ideas out there?

Try to determine the exact area on or in the engine that the noise is coming from. A mechanic's stethoscope will help a lot. Also I believe your GPW has the external type parking brake shoes and drum. These can develop a very distinct metallic rattle as they wear.

This is the external type parking brake at the rear of this transfer case.

Another source for a rattle is the front crankshaft pulley when it works loose.
