Block filter bypass valve

Cons: If for ANY reason the filter fails or gets plugged, you have NO oil AT ALL.

The relief valve opens on a pressure differential. It only opens when the filter is clogged and becomes a restriction. This is an obvious benefit for those who never bother to change their oil &amp; filter. If you stay on top of oil &amp; filter changes you should never have a problem.

That said, in the event of some sort of fluke filter failure, personally I'd rather have unfiltered oil circulating through the engine than none at all.

I don't block mine, FWIW. </div></div>

I agree 100%. Probably one of the most hotly debated topics outside of &quot;manifold vs. ported&quot; vacuum advance. I firmly believe a working bypass is a good thing on any street / strip car.
