Weird question, but is there a way to hook up a bypass filter to a 97 5.7 vortec? I assume it's way to overkill for an engine like that.

My buddy's dad had a Franz filter on a Toyota motor home with 230K.
I was there one day when they were changing the oil and filters. I remember he had about 4k since the last change.
The old oil still looked new. The Franz filter used toilet paper roll for the filter medium. When it was taken out, it was totally black from all the junk a normal oil filter can't filter out.
If i owned anything worth putting one on, I would do it without hesitation.
OEM oil filters are "full flow" design. ALL the oil that comes out of the oil pump goes through a filter. The filter has to flow well enough that it doesn't starve the engine. Therefore, it's a fairly coarse filter. Better than no filter at all...but not intended to remove fine debris.Bypass what ? For what purpose?
I've thought about trying a bypass but not sure you will ever see a cost return. They claim it cleans the oil better and gives you longer oil life.
I'm paying $60--$90 for those SKY Frantz filters, plus some hose and brass fittings. Oil change intervals are dramatically extended. They'll pay for themselves even on 5-quart systems IF (big IF) you can stand to leave the oil in the engine until it actually NEEDS to be changed. Most folks can't, based on psychology and marketing. The just get squeamish at the oil change intervals allowed by keeping the oil clean with a bypass filter. There's also the additional engine life as a bonus.Just change the oil. Bypass makes sense on tractor trailers, when your engine takes 15 gallons. Our trucks... not so much.
Yup. Those bypass filters--Frantz and other brands including Amsoil--do a marvelous job of removing grit of nearly any size.I was looking to do anything I could to preserve my parts investment with the
best oiling setup that could be pieced together. This is where a buddy's dad demonstrated a Frantz oil filter's performance...
...I ended up mounting this filter ahead of the radiator... ...Cleanest oil I've ever run... ...whenever I pulled the valve covers to check the lash it was spotless inside.
Yup. First Frantz went on the boat. My second Frantz filter is on my solvent tank. The third was installed on the '88 K1500. There's no grit coming out of the solvent-tank nozzle, but the solvent is still dark and ugly because the Frantz filter is not going to remove LIQUID mixed-in with the solvent--trans fluid, used engine oil, paint thinner, brake fluid, gear lube, etc.One more quick Frantz story. Years later we had a solvent-based parts washer where the (kerosene? diesel + ATF mix? I don't remember) just seemed to get filthy fast and stay that way. I ended up buying a NOS Frantz filter & plumbed it into the parts washer, and this seemed to make a big improvement. (ie: At least the solvent no longer felt gritty out of the nozzle.)
Bypass OIL filter?
...Hardest part is getting a suitable return fitting so that the oil can re-enter the engine somewhere.
...to threaded port in Marine oil pan.
