valvetrain noise 440

challenger · Post by **challenger** » Tue Jul 07, 15 9:32 pm

thanks for the input fellas, drew, 20-50 morris golden oil (british brand been around since the 20.s) oil pressure (hot) 40 idle 75 cruise and flat out carl, this is a solid cam not hyd, valves wont bounce at that rpm unless they proper knackered,headers have new gaskets and sealed well

dave, galley plugs clear, i have wondered if using a thick valley plate rather than bath tub gasket acts as a box and amplifies valve train noise ?? ive done around 200 miles in this so far and hasnt got any worse but no better either, before nats i will fit new plugs anyway and double check pushrod clearance

Some flat tappet cams are just Plain noisy Jim,do tappet clearance as cam card

That is great oil, I didn't see that you had solids, and yes they will make even more noise with the lift in the cam,drive it, and see,It should stay together ,run it

Alloy heads on a steel block requires 0.006 tighter than steel heads when set cold.

Jim,
sounds like mine to be honest

Only my headers aren't sealed as good as your right now
