Another oil bypass question

[tbonetoyama]

I wanted to know what orifice size is needed in the feed line to maintain proper oil pressure. Lots of opinions on which oil bypass kit is best but I like to know the technical stuff. Can anyone help me find any threads on custom, home built systems?

The Amsoil by-pass uses an orrifce around . 035 as I recall. Will only allow around 6 quarts of oil through it in 5 minutes.

I've used the Amsoil by-pass and the FS2500, and like them both. The Amsoil by-pass seems to be a bit more user friendly, but I currently have the FS2500, as I've sold the other truck. I believe the orifice in the FS2500 is around the same size as the Amsoil, according to the post above. As long as it will circulate the oil at least once an hour or so, it should do it's job fine. You need the circulation to remove contaminates, but you don't want to lose oil pressure to the engine and turbo, either. Circulation time will also depend on your current oil pressure, oil viscosity, and oil temperature.

Are the bypass units worth using with non synthetics or should I wait untill I switch to synthetics?

we use a . 032 drill. they work very well on dino. in fact because of the in-cylinder egr used on your 06 there is no advantage at all in synthetic, the carbon loading is so great that they have to be changed at the same duration. a good bypass filter does help with the wear and extends the oil change interval some. the dirtyer a filter get's the better it filters. for the bypass filter run it until it no longer passes oil. about every three months just put your hand on the filter after a run, if it is hot it is ok. we build our own kits using filters for the big rigs. i use filters that i stock for them. they hold a lot of oil in fact the one i use most ,the luberfiner 9750 holds one gallon. at oil change i drain the filter and replace. the oldest truck with the 9750 has about 350,000 miles on the same filter. that truck is on a 12 valve. on our cr the most is 150,000 at this time but it is still flowing and i think it will last for a long time to come. if you get rid of the in cylinder egr you can get about 40% increase in mpg and the oil will stay a lot cleaner. it will cost you about $3,000 but if you drive any miles at all the payback is very fast

Too me, I think the greatest benefit is the collection of the smallest contaminates and carbon. With my trucks usually fueled pretty good, they tend to black the oil pretty quick, so the extra filtration helps ease my mind that they are getting plenty of protection from carbon deposits that might slip past the rings, not to mention sand and other small particle that happen to make it past the air filter or into the engine. My trucks are all run offroad extensively, in dusty, hot conditions. I've got several 100k on several trucks, and I haven't had any problems with oil pressure or excessive wear. In fact, I think they have better oil pressure than a lot of trucks I see on the highway that don't have the same filtration systems. If I can run that truck another 250k versus buying a new one to replace it, it makes the filtration systems more than worth it. Again, the amsoil uses a spin on filter, while the FS2500 uses a cartridge type filter. I really prefer the spin on filter, but the FS2500 is what I have right now, so it's easier to keep just one type of filter in inventory for several trucks.

I respecfully disagree with you regarding your statement; "because of the in-cylinder egr used on your 06 there is no advantage at all in synthetics".



This is why I disagree:



High quality Synthetic Diesel Motor Oils are heavily fortified with detergent/dispersant additives and are naturally resistant to soot. they are designed to keep soot particles suspended independently and prevent them from attaching together to form larger, wear-causing particles. Viscosity increase is minimized and soot-related wear is controlled.

Excersize and fish oil and other medication is like good for the heart. Another term for bypass filter is "fish oil".

Another by pass question:

Is there another spin on by pass oil filter that can be installed in place of the AMSOIL EaBP 100? on the BK filter head?.



Thanks,

I have the remote bypass which uses 2 filters. One bypass and one regular filter. I use a Mobil filter for the regular filter but I have not tried to find a bypass replacement.

CKelley1, I'm not familiar with the in cylinder egr system but how do you get better mileage? I understand that egr removal would keep the oil cleaner for longer but did you mean that you get more mileage out of the oil because it's cleaner? Cause 40% increase in my mpg sounds outstanding if it's true!! I've heard of the luberfiner, amsoil kit, fs 2500, oil guard... etc. but has anyone seen the kit on ebay from NUC Motorsports? The price is right. Uses an amsoil filter but I haven't gotten a response about orifice size.

I'll try to get the number off of it, but I have some on my tractors that uses an LF670 or LF777 filter, which is huge. I keep these filters in stock, as they are the primary and bypass filters for most Cummins Big Cam engines, so the newer models that only have one, get another. The filter head can be purchased at NAPA, Oriely's, etc. fairly cheap. I think I have the Carquest number in my KW or in my work trailer... ... if interested PM me, and when I get time I'll swing down to the barn and get the number.
