Noisy Lifters
On the 57 Saratoga, we rebuilt the engine ten years ago and only recently got the engine running.
We are now trying to solve the problem of noisy lifters. All of the lifters clack all of the time.
After running the engine we removed the valve covers and found only a little oil on the under side.
The rocker shafts are lightly oiled but not as wet as I expected.
Although the dash gauge registered good oil pressure, we suspected the oil pump.
The oil pump. Looks to me like it was new when we rebuilt the engine.
Another view of the oil pump. The pick up screen checked clear, and the bypass valved checked OK.
On this engine, the oil pump is in the oil pan, mounted to the rear main bearing. It is a lot more work to replace one of these as compared to the external pump used on the wedge engines.
Here is the engine with the rear main removed, showing the oil gallery check valve. These are sometimes left off during rebuilds and we decided to check.
