Valve Head Noise LOUD TAPPING

[supraflymkiii]

Doesn't sound like rod knock. There is also no adjusting to be done with the stock lifters. The only thing to adjust valve lash is with shims. It kind of sounds like an electrical arc. You should try and replace the plug wires, one might be cracked and arcing on to the head. Also I doubt that it jumped time I've never heard of it happening to anyone on these engines. To check timing set your crank to 0 deg btdc on compression stroke pull your camgear cover off and make sure both the stamped lines on the cam gears are pointing straight up. Then to make sure get a timing light and make sure your timing is at 10 deg btdc.
