My 422 smallblock build
Wellllllllll, took another step backwards today. Fired up the car after work today noticed that the rocker noise on the driver side seemed a little louder than normal. Thinking that it was probably just the valve lash being a touch loose, I let it warm up on high idle.
When the noise didn’t change with some heat in the motor I shut it down and decided to pull the valve cover and check the lash. Well, it was loose alright. Somehow the pushrod had come unseated from the rocker adjuster and the top of the pushrod commenced to beating the adjuster to death.
Upon further investigation, I noticed that a few of the pushrods are getting discolored on the rocker end due to getting really overheated. That tells me we have an oiling issue at the rockers. The gauge reads 75psi cold, 60psi at cruise, and 40psi hot idle. So she’s making good pressure and it is a HV pump. Must be a restriction somewhere in the rocker shaft assembly.
The plan is to remove the oil pump drive and install my priming tool and spin the pump to see what’s going on with the oil at the rockers.
