Valve train noise in a 32 valve
In my 85, what is "normal" valvetrain noise? My 16 valves didnt make any noticable noise after start up. This is my first 32 valve car I have that runs. what is normal?

The drain back vavle is only there to keep the oil in the heads when the engine is not runnig. Since your is making noise all the time, I would guess that its at least one or more hydraulic lifter not keeping pressure.
