Re: High Oil Pressure...HELP

I was hoping for a more thorough oil pump inspection. Too late for that now.

Try running the oil level one quart over the full mark on the dip stick to stop the clatter problem.

If that doesn't work then hopefuly the problem is just a stuck lifter. If freeing up the lifters solves the problem then all is well.

If not then a worn oil pump shaft is notorious for the lifter clatter problem on the Packard V8's. I have a quick band-aide fix for that once all other issues have been exhausted.


While the valve cover is off, look inside of the valve springs to see if there are umbrella type seals riding on the valve stems. Check all of them. They should not have dropped down onto the valve guide. If the seals drop down onto the valve guide it will starve the valve for oil thus causing the valve to stick. This is dangerous because the valve can then hit the piston. Sticking valve will cause clatter too.
