Rocker oil pressure

[John Pasinski]

I just had my 402 engine overhauled (well pretty much). (1) new piston (cracked). Reman 402 crank kit, all rings, all lifters, new oil pump. The engine developed a lifter clack (driver side). I pulled the valve cover, and #1 intake rocker, and #5 intake rocker are not receiving oil through the push rods. I checked the push rods for blockage, both clean and clear. I haven't checked the pass. side. The others are kinda drooling the oil up through the push rods EXCEPT for the #3 exhaust rocker that one is peeing out the oil onto the inner fender. This is of course while the engine is idling @ 650 RPM (standard trans.). What should be proper amount of oil be at the rockers at an idle? Does this mean I have at least (2) defective lifters? I appoligize for the disertation, but I have to figure this out without help as I am all alone. No old timers around to help. Thanks...............

I remember that they (if not clipped) will squirt far enough to go past the engine and get on the exhaust manifolds, etc. Are you sure the oil pump is ok? Was the block properly cleaned? All oil passages feeding lifters cleaned well? What weight oil are you running?

[John Pasinski]

The engine block was cleaned when it was disassembled. I'm running 5W30 oil because everythine's so new. Pump is new. ALL parts were purchased through NAPA. Is it possible these are the incorrect lifters for a 402? Maybe there are others that will fit but not be able to pump up or line up with the oil galleries. I'm just throwing out guesses. I really have no idea what may be causing this.

My 402 has had a slight tick in it since it was rebuilt. I replaced cam and lifters twice thinking cam/lifter issues and still have not cured the problem.
