[DeTomaso] Scary sound from the 351...

[Tomas Gunnarsson]

Henrik,

Remove the valve covers and look for any loose parts. That's pretty much what you can do without digging into the engine for real. Is it possible that the fuel pump is making the noise? I've also heard of the harmonic balancer moving around leading to contact between the back of the balancer outer ring and the engine.

> My Pantera was finally ready for the inspection yesterday. When I ran the engine for about 10 minutes to see if that the cooling was working fine the engine started to make a mechanical sound when I got over 2000rpm. It sounds like there is something moving around inside the engine. I changed the oil and filter and tried again. When I started the engine with new oil the sound was very distinct a couple of seconds before the oil reached the whole engine. After that the sound was a bit less then before the oil change but still there.
