Bypass oil filter questions

[LRWatson]

My proposal is to use a Parker hydraulic/lube oil filter as a bypass unit. It can be had from WWGrainger including a 3 micron filter for less than $26 and replacement filters are less than $14. A pressure guage can be installed for less than $10 to measure the differential pressure to indicate when the filter needs to be replaced.

I propose to supply the Parker from the currently-plugged port on top of the full-flow filter and return into the valve cover with a small flanged fitting. If needed, a needle valve installed on the supply-side of the filter could be used to control flow volume so that engine oil pressure is not reduced to dangerous levels. I can fabricate a mount for the filter adapter for near the passenger battery to use the tapped holes in the filter mount and this will help to keep hoses short/cheap.

With a few plumbing fittings and short hoses, this system should be up and running for less that $75 which will make payback pretty short.

I have not been able to find retention figures for the filter at the 3 micron level.

What pitfalls does this scheme present? Thanks for your help.

Most good bypass filters filter to less than 1 micron. At those sizes the particles polish rather than wear meal. Its impressive to look at crankshaft bearings than have been in the motor over 100,000 miles with a good bypass. They look like mirrors with no wear on them at all. I use Puradyn filters. www.puradyn.com These filters have a heating element that gets rid of water, anti-freeze and fuel that gets in the oil. No other bypass system has this or has been around as long as they have been.

Do you know how efficinet that hydraulic filter is at removing 3 Micron particles? A screendoor can remove 3 micron particles, but it wouldn't be very efficient at removing that size particle.



You will certainly need a restriction in one of the lines of the filter, most by-pass systems restrict the oil flow. You would need to know how much flow would be required so you could keep the filter flowing at its best rate of flow of the filter element.
