Pretty much an idea before real filtration took over. Messy to service and not overly effective. Imo.

It was the beginning of filtration & certainly better than none at all , hindsight is always 20/20 !

Back in the 1980s I watched a co-worker at a shop I worked at change the paper in his Frantz filter. I decided then I would never use one.

2nd hand knowlege (Im 40) but there was a rash of these issues with fleet vehicles in the 70s. My Pops moonlit at a small dealership after hours doing R&R on plastic tipped timing sets and camshafts for some fleet accounts. Mostly 307s but some 2bbl 350s as well. After the first few had problems, the fleet manager decided to do it as preventative maintenance. Only other thing I remember Dad saying was that some of these had added a supplimental filter that used a roll of toilet paper. No Im not kidding. Toilet paper.

MANY years ago J.C. Whitney catalog contained just such a filter using a roll of toilet paper.

You need to be careful who you buy cams from these days.
Lots of junk manufacturers who have 5 star ratings selling oil pans. The oil pan is a stamped piece they sell for stupid cheap. Not much there to mess up so they get a 5 star rating. The more expensive camshaft may not be even hardened. But they have that 5 star for that oil pan so on some sites it shows them rated at 5 star.

Lifter bore clearance is your problem. They need to be checked. If tolerances are too large the lifters will side load, rock, and not want to spin like they should. Excessive tolerances in these bores. They sell sleeves for this repair.

I've had 6-7 cams go flat over the years, in Chevys. It was mostly back in the day when they were playing with the zinc in the oil while we slept. I've lost them with all kinds of oil, even Mobil 1... It got to where I could hear it coming on and just change a damaged lifter or two, and keep going.

Then I switched to Super Tech 15-40 CONVENTIONAL OIL, and they stopped going flat. It still had zinc in it, because it was used in older diesel tractors. I like tractor oil! .

Then I installed a WIX auxillary bypass filter (#51051) of 5 micron, and switched to roller cams, so I could use lighter oil and make more power and get better mpg. Havent had any problems since. Works for me!

Hello so I've been told back then when a sbc started having issues of a flat cam mechanics would replace it and be on there way. I wanna know if anyone's done that before and had no long term issues. Would super small prices of metal be able to pass through and not be a big worry for the new cam break in? There would have to be some left over if the cam was going flat over time. The oil filter would catch the big stuff but there's gotta be atleast some super small pieces in there that can go through the passages and not hurt anything.thank you

if its a high milage engine and the cam is worn more than likely your rings and bearings are worn. No amount of metal running through your oil system is OK. On a new build it would be a disaster.
