Hi, Ernie,

That's typical of most original Packard V8s.

What oil are you using and what is the hot oil pressure?

In the summer, use 15-40, but in fall, use at least 10-40 and overfill by 1/2qt. This should help the problem.

However, once it starts, it only gets worse. Back in the day, some Service Departments patched the problem by replacing the main bearings.

Today, you can replace your worn oil pump with a kit developed on this forum which uses a new Oldsmobile V8 pump. This often solves the problem for most owners. PM me if you are interested.
