Intermittent knocking sound, '72 318
 

I have a 1972 dodge dart swinger with a 318. and for weeks now I have had this knock that comes and goes. its heard from the engine compartment and kinda towards the drivers side. the motor is built up and has a pretty aggressive cam. I've had a feeling its in the valve train somewhere just based off what it sounds like but I could be wrong. any ideas on what it could be?

It's an unknown without more info.

I'm Kind of with Lynn..... But.. Pull the valve covers and check to make sure everthing is in order. Check the lash while your there also....

will do. thanks racerhog.

Run for a short time without belts.

Check the torque converter flex plate and bolts.

Have a look at the harmonic balancer for straightness, looseness or rub.

Turning crank back and forth can show any looseness or noises.
