Default Bypass oil filter

The company i work for makes bypass oil filters for just about everything and I have seen how they keep the oils clean. they make a small filter that is really cool looking and i want to put it on my 02 a4 . is there a port to pick up oil pressure other than under the intake? I will post a pic of the filter when i can figure out how to do it.

if you look at any of the oil pressure bypass threads it will answer your question.

I think there is a port next to the oil filter??

I was told that they have police departments going past 10,000 miles before oil changes.this filter cleans down to 1 micron and the filter housing is extruded alum. with what looks to be cooling fins.I can mount it directly behind the pass. cooling fan. ooo there is a oil port behind the p/s pump. looks like it will be a quick install after i fab a bracket. ill show pics when done.

If you take oil from the port behind the p/s pump, where will you put the oil back into the motor? Personally, I would avoid complicating your motor's lubrication system any more than necessary. What you have now is pretty bulletproof and reliable. What's so bad about the OEM style spin-on filter anyway? I think you can actually get machined aluminum, cleanable filters with ultra fine stainless screens. Lots of money if I remember correctly.

I disagree. I think it sounds like a great idea to modify your system. Post the results

In addition to the above concern, a secondary oil flow path will also result in somewhat lower oil pressure.

I'd leave well enough alone.

Unless your new filter is capable of removing fuel and water from the oil I don't see how it will extend the useful life of the oil.

Reinventing the wheel?

Since 1955 and the advent of the 265 CI Chevrolet V-8, Chevrolets have been known for many features which have made them the universally accepted performance engine of the world.

One of their better known traits has allways been a bullet-proof lubrication system.

I thought that to. Some of the people here use that port to oil their blower. the filter does filter out water.I looked at the test and the oil is cleaner(particle wise). than when it went in. I just thought it would be cool.

Any water in 200 degree engine oil will be quickly vaporized, and then evacuated by PCV system.

The filter that you're describing is probably more suitable for water removal in hydraulic oil systems, which operate at much lower temperatures.

I know they do real well in hydraulic systems. most engine wear is done by paticles in the 5-20 micron size . this filter filters at 2 microns so it will keep the ring pack clean helping the rings do a better job of sealing.and thus allowing less cumbustion gas to escape past them into the oil. i have been busy at work (buyer @ truck dealership) so havnt had time to mess with my baby.

Any lubricating oil flow used for a bypass style fitration system is obviously being diverted from the lubricating system, how much flow will you filter require to work?
How do you know that most of the wear particles are in the 5-20 micron range, was there a particle size distrubution analysis performed on a used oil sample, or is this an assumption based on filter media micron rating for off the shelf spin on type filters?
I think you are trying to solve a problem that does not exist. There are plenty of C-5s on this forum with more than 100K miles, some over 200K and one at least over 300K, all these miles with stock filtration systems with spin on full-flow filters.

I am told that it diverts 10% of the oil. I read a sae paper that states most of engine wear is done by that sized particles.I am not trying solve any problem nor do i put alot of miles on my vette.I do understand that this would be more trouble than its worth but what the &*^& . I do like the idea of the oil in my car being maintained to a level that is cleaner than out of the bottle.
