Re: blood guts and the beer

Interesting info. I didn't quite get the bit about beer - until I saw the pix posted separately to the gallery.

As for the oil filter, it always looked like an afterthough to me - even on straight eights, and not just on Packard. When you factor in the higher frequnecy of oil changes back then, partial-flow filtration was probably better than none at all - except for the V8.

Lifter noise and oiling issues with the V8s has been a hot topic for all the years that many of us have been online - over three diffrent forums. You're not off-base with your thoughts on removing the oil filter unit form the V8s. Let me explain.

With an OE pump modified to include a lower bushing in a thicker bottom plate (with vac pump eliminated) AND an upper bushing in the oil pump body, member PackardV8 still experienced lifter noise when coming of a highway run, with engine at normal operating temp. I believe he had also installed the late design camshaft thrust plate and spacer. Yet, he installed a shut-off to the filter and found that turning off flow through the filter eliminated that lifter noise.

This supports my position that the vacuum pump is not the culprit that some think it is - though it may contribute to premature wear of the pump driving shaft bore. The Olds V8 pump adaptation give more volume and pressure, but I think there may be more to the V8 oiling problem than we've seen.
