383 engine noise question

pomonamissel said

buck351 , had the # 2 cam bearing rotate on a 66 383 , thats showed itself in the cam valley although . bearing had come out a bit . also have you checked your valve springs , could have cracked one and now it broke . i have never had problems with the fuel pumps on my 383's , just my 440's .

Good point. Didn't inspect the springs while I had the valve cover off but it would be an easier fix than a rod. They are the original. Have to pull the cover back off and check. Having never seen a cracked or broken compressed spring I assume it's obvious. I was surprised they didn't replace them. The rebuilder just checked and shimmed them as needed to get the correct tension.

First fuel pump I had do that and I've had the car since it was 1.5 years old. Usually they start leaking gas out the vent hole from diaphragm failure. This one was making noise that stopped after I replaced it. There was a little free play in the existing fuel pump arm that wasn't in the new one.
