Strange Timing Related Noise.

64672 · 2025-08-23T20:50:24Z

With my timing set with a light on TDC. My 216 is quiet at low rims in the garage and on the road. At 15mph in first, 30 in second or 45 in high, it starts this sound like an old diesel injector pump. Disconnected the vacuum advance and the sound moved up in rpm's. Still showed up though. However, in the garage, I could not make it rattle at any rpm. With vacuum advance connected, it would rattle in the garage. Disconnect and there's no rpm in the garage where it rattles. Please! Would appreciate some help. Thanks

Hi Roger

Just to be sure, was the same distributor used before and after the engine rebuild?

If so...because you say you drove this engine for 18 years without this problem, and it suddenly showed up after a rebuild, I suspect the problem is not with your distributor.

So, that brings me to questions regarding the rebuild.

Did you do the rebuilding yourself? Or did someone else do it?

And, what exactly was done?

You say the block is from 1950... exactly what parts are from 1940, and what parts are new?
