Reply to "Excessive oil consumption"

Agree with my friend George on the oiling issues. I have blown an oil filter clean off the block at high rpms: 50-wt racing oil AND a high pressure spring were the cause. I was NOT the most popular guy at the track that day; clean-up took hours.

Also note that extremely high oil pressures on some 351-Cs with hydraulic lifters can & have caused premature valve float! We had one fully-pro-built Pantera in the area that acted like it had a rev limiter set at 4500 rpms, until the owner, after being nagged by us, installed a brand-new STOCK pump in place of his 'high-pressure' assembly. Immediately, the same engine revved to 7000 with no other changes! Apparently, very high oil pressure overwhelmed the bleeds or check-valves in his lifters..... Such high pressures & flows have also been known to erode main bearings, as well.
