Ok, this is not exactly Mopar related yet has people stumped. Last year I took Dart heads off my 302 because in the end I wasn't happy with them. So I got my original 302 heads rebuilt and a very nice job it was. Took the other heads off, installed these, changed out the cam for another, slipped in 16 NOS Ford lifters and ran the engine. All went fine. Afterwards took off the valve covers to fine tune the valve adjustment. Stopped there and did electrical updates through the year. Last week I ran the engine to do a final check on timing, carb adjustments and idling speeds. However, in 20 minutes of running I hear a metallic tick which seems to come from wherever your ear is. So I shut down the engine and let it cool off. A week later, yesterday, I took the valve covers off and the tops of both heads and the rockers are dry as a bone. No oil anywhere. I spun up the oil pump with my drill and still no oil after a few minutes of that??? So I pull the intake today and guess what? The valley clearly has had oil running over it. All lifters are normal. In fact no damage to the roller rockers or the valve stems. Now I spin up the oil pump and I flood the valley with oil out of the lifters. Put #1 rocker assembly back on but can't get any up up to the rocker through the clear pushrod. Now I am really stumped!
