You will be filtering all the oil with a bypass system, true it is taking a small slip streem of the oil and filtering it down to a micron level but at 55mph all of your oil in the system will pass through the bypass filter every few minutes keeping it very clean. I have been really impressed with the spinner II's at work so I think I'll give that a try first, not having any filters to replace ever is pretty nice, along with the 1/10 micron filtration capability.

The spinners are definatly nice. Where would you mount it?

I think (NOTE my opinion only, I have not checked) that they may capture only some of the particles at 1/10 micron. They are catching at the absolute level at something above that, maybe 1-5 microns. Either way (spinner or 1 micron filter), it is overkill if you are going to change your oil every 3-5000 miles.

If you are going to do it, filter, sample, have it tested, and decided when to replace the oil from the test results.

bgkast, I got the base in the mail on Saturday. It's not an Amsoil base, but it will work with their filter.

I'm going to use the oil filter housing as my "dirty" oil source. I'll drill/tap a 1/8NPT fitting into the housing and plumb the return to the valve cover. An Amsoil EaBP90 will be my filter of choice (LINK) since they claim it will filter out soot. I'll also add a sampling petcock to the inlet so I don't have to get my hand covered in oil to take a sample.

I'll also switch over to Mobil Delvac1 and see how far I can extend the drain interval based on oil analysis. I probably won't want to go past 8,000miles no matter what the analysis returns.

Out of curiosity, do you have a picture of how they used the oil cooler line as a source?

Lance- sorry, I dont have a picture. Basically what they did is cut the oil cooler hose, inserted a barbed T and threw on a hose clamp.

All the lines/clamps were intact? I didn't see anything bad on what you included.

I think that the T that they put on the oil cooler line was from a hardware store. I had to leave the T with the oil cooler hose because the hose had hardened around it. The other hose was plugged on to a barbed fitting on the valve cover, but that fitting is 350 miles away so I didn't include it.

That's fine. I have all the fittings I need at work and I can get a few feet of hydraulic/oil hose at Parker Store for a few bucks (Maybe I'll get my VNT turbo oil tubes/fittings at the same time.).

It is not off the floor.

The cotton comes from a rendering plant that extracts the fiber from the seed. Yes some stems get into it but so what they are not going anywhere, like into the engine. They are way too big to get out of the filter. Cotton is an excellent filter media and perfectly suited for doing the job.

I love the smell of diesel smoke in my hair

How does that work!!??
Mine turns black in about 10-15 miles

The oil thats flowing to the oil cooler has not been run thru the filter (the TSM calls it "oil in an uncleaned condition"), IMHO, you want to make the bypass filter last as long as possible by redirecting a portion of the oil directly after it has been thru the primary engine oil filter.

I love the idea of reduced soot and longer oil change intervals, but $500 plus $22.95 (every 4k miles?) is unacceptable for a car that cost me $2k.

I'm aware. It just looks like it because of all the crap in it. I don't care if its an extremely remote chance that that stuff might get into the engine, I don't want it in my filters. Cotton would be an excellent filter media if it was nicely packed and wound correctly, like in the Turkey Fram filters. I'm not real fond of loose stuffings that allow the oil to channel. Maybe that's just me.

603 puts out less soot, and Delvac 1 suspends it all, so it all drains out.

Another interesting bypass option, like the spinner2, is the dieselcraft centrifugal filter. It works from oil pressure by spinning the rotor with 2 strategically-placed .040" jets, and is supposed to filter to a sub-micron level. It is currently getting a lot of press on the InfoPop SVO forum because people are testing it for use as a WVO cleaner, but it is advertised as a bypass lube filter as well... Apparently, according to the people on InfoPop, it works quite well in both applications, and at $200 it is a little less pricey than the spinner 2, I think.

www.dieselcraft.com

I have an Oilguard bypass www.oilguard.com on my Dodge Cummins it does not keep the oil honey colored even the guys on www.dieseltruckresource.com with the FS2500 say that it will not keep oil new looking in a cummins.

ive had it on there for about 16000 miles and did one filter change on it. im about to have the oil analyzed soon.

but it is a good idea in theory.

These filters don't extend the additive's lifespan in your oil cycle do they? Is there any point to using these unless you want to do synthetic and change it at 15K?
