Remote Oil Filter (235)

I have a '60 chevy 235c.i. in my '51 chevy, and it has a remote oil filter , I think they are called by-p*** filter... I changed the oil and was wondering if I can make the hole in the metal tube inside it larger ,or drill more holes in it ... because it's only got one little (maybe 1/64") hole in the side of the return tube inside the canister,... or would drilling more holes screw it up?
Thanks.

 

the way that a partial flow filter works is this... a very small amount of oil is diverted to the filter to be strained of particulate, then instead of getting sent back into a pressure galley, the oil simply gets dumped back thru the return line into the pan. if you make any modification at all, consider full filtration first. check out the Inliners International site for details on the mod, but it goes something like this...all of the oil pump's output has to be diverted into the filter. i dont know all the particulars about the 235 but in the GMC, the vertical p***age at the pan rail has to be tapped and fitted with a shortened pipe plug to divide the feed into an upper and a lower chamber; then the lower chamber is drilled and tapped with an intersecting hole for the line out to the full-flow filter. the return line is plumbed back into the old feed hole for the partial flow filter. of course surgical cleanliness and removal of any metal shavings that could migrate into the oiling system is obviously very important. the current reproduction of the "Hildebrandt" oil filter that someone is selling on e-pay is traditional enough looking, and hides a spin-on filter inside.

 

Drilling this metering hole larger or adding more holes will drop your oil pressure!

No need to push more oil through a byp*** filter.
It takes only a few minutes for all the oil to go through this type of filter.

Byp*** filter elements can filter particles much smaller than full-flow filters.
The Frantz byp*** filter with toilet paper element traps particles down to 1/10 micron. - These filters are still being made and sold today and have been in use for decades.

Big rigs use byp*** together with full flow filters, which only filter down to 20 microns, to maintain flow.

 

I read that a byp*** filter will filter ALL the oil in your engine every 6 minutes at 50 mph once the engine warms up. That fact, plus filtering to 1/10th micron is good enough for me!

The full flow filters all have a byp*** valve built into them. When the oil is cold or too thick, it byp***es the filter and gets pushed directly INTO the bearings! Plus, they only filter down to about 15-20 microns.

You make up your own mind about whether full flow or byp*** is better...

 

Thanks,...I think I'll leave it alone.

 

I wonder why GM went to the full filtration in the 58 model year?

 

With a byp*** filter, the main bearings get dirty oil before filtering.

With a full flow filter, all the oil gets filtered right after the oil pump.

Both systems together give best protection, like on big rigs.
