Oil leakage around rocker stands

I was pre-lubing my engine on the engine stand today. We noticed a lot of oil leaking out past the rocker shaft hold down. Never really noticed this before. Has anyone seen this or rectified it before?

I did take one of the stock hold downs and put an O ring between the shaft and the hold down. Stopped the leak on the top but there was still a leak between the pedestal and the shaft....

Maybe it is time to check the shafts for out of round at the mounting holes Good find
There are fixes for all problems, determining the cause and fix is the hard part sometimes
Which motor?
Let us know what you find

Shafts are round I mic'd them at assembly. Max. .001 out of round. The O ring fix's the top. Just wondering if there is something I can try under the shaft between pedestal and shaft?

Its a 340...

put a film of anerobic sealer on the pedestal. It won't come off & get in the oil.

Thanks Rick... Never heard of this sealer before. What is the consistency like? Does it get brittle like Loctite? Or is it closer to a silicone consistency?


Rick Have you ever tried using the Anaerobic sealer on the pedestals before?

Use it sparingly. It gets hard when it cures and may need to be chipped off during disassembly. I've used it when I had tapered shims under the shafts.
