any problems with oil press,and bypass

[rparlaman]

I was thinking of installing a amsoil bypass but i heard that there is problems on oil problems and the bypass system. Any in put would help

PS That is oil pressure problems.

I can not say if there are any oil or by-pass problems. Usually with any add-on type kit like you speak of, there are fitting and line issues, most of which are leak related.

The engine itself has ample oil pressure and it's internal by-pass is set at about 80-85lbs. I really do not see a need to alter the stock oiling system. I know there are several kits that are available, but i think Cummins did a great job, and they are UN-necessary.

I have been running the amsoil dual bypass system for 50,000 miles so far and there isnt any pressure drop with it until you use synthetic oil and then it dropped to maybe 39 from 40 psi. The advantage to the bypass system is filtering the oil to 1 micron instead of 30 that the stock filter does. I would go with the single bypass system if I was doing it over again because the dual system primary filter is the stock filter moved up alongside the bypass filter. With the single bypass system you leave the stock filter in the original location and come off the top of the filter housing to the bypass system and route a return line back to the valve cover. This cuts way down on the chance of a leak and works just as good and is easier to mount as its smaller.

Check out my "Readers Rigs" pages on Amsoil By-pass oil filters. There is Really NO ISSUES concerning oil pressure with the Amsoil by-pass systems.

I have had my Amsoil Dual Bypass system in operation for almost 100,000 miles. I have used Amsoil 15W-40 Marine Diesel Synthetic Motor Oil since about 10,000 miles (190,000+ on the odometer as we speak). I also used CPFF's billet mount and braided steel lines instead of the Amsoil hardware. No leaks, ever.



There was and is a drop in oil pressure on the oem idiot oil pressure guage with the installation of the bypass. The oil pressure is about 42 psi which is down very slightly from the stock Fleetguard set up.



There is no doubt whatsoever that synthetic motor oil does a better job of lubricating the engine and resists thermal oxidation (sludge buildup); which keeps the engine clean.



There is also no doubt whatsoever that the Amsoil dual bypass does a much better job of filtering the oil. If a filter is added that filters out smaller particles than the stock filter set up, then it does a better job of filtering. Is this better oil filtration going to increase the productive life of my engine; yes. If it is said that better oil filtration if unneccessary; is better air filtration unneccessary? All filtration is good, some is just better than others.



Synthetic oil + better oil filtration + better air filtration means less dirt in my engine = less wear. Less wear means I will have better cylinder compression when I get to 1,000,000 miles.

I know you guys like the remote dual by-pass filter, and it probably is a good one. But I still think it is just a BLING-BLING type thing. Is it nice to talk about,YES. Do you need it, NO. I would think if one was to enlist the help on a Quality oil and a quality oil filter, there oiling needs would be meet. I have used item like those mentioned, extra oil cooler, remote filters, etc. But the main complaint is why complicate the oiling system when it work well enough on it's own?? Cummins engines are well known for there ability to last, many, many users get over 300,000 miles out of there engines without any major problems. That tells me Cummins did a great job in the design and manufacture of this engine, and I do not see any reason to mess with, or modify it's present oiling system.



I am not saying your by-pass filter thingy does not work, or is not helping. Just what made you think it was time to "improve" upon a try ed,tested, and extremely dependable oiling system?

 

[DOWG]

y-knot, you have a point; I do like things simple, the simpler the better. In fact because of the simplicity issue I almost removed the bypass this weekend. Reason? I had just spent several hours fighting with PDR's turbo boots to get them on and when I finally did there was almost no room for the heavier spring loaded clamps that came with the boots in between the braided steel oil lines. I almost couldn't get the boots on, and I was darn sure not going to take 'em off after all that trouble.



Having said all that, for a couple hundred bucks for the by-pass, it is a cheap upgrade that just might pay big dividends later. I practice a policy of overkill preventative maintenance; replace before failure and fix whatever it is, now! 300,000 miles is great, but it will be here pretty darn quick for me. My truck runs better now than when I bought it and the last three years without a truck payment sure feels good; I want that feeling for as long as possible.

If you think that the stock system cant be improved on by some one willing to maximize filtration results by spending a little more money than the bean counters at the factory will allow then so be it. Others of us understand that the factory must use cost cutting measures to be effective in the market place and that "good enough" just isnt when better can be had for a few bucks.

You guy's do what you must, I have been down that road and will never return. I believe there is absolutely nothing wrong with the Cummins bone stock oiling system. I too believe in maintenance over kill, I replace thing just to be doing something. I change oil filters at 2000 mile intervals. That is my form of oiling system protection, that and the synthetic oil. I do not want to install anything that gives the chance for an additional oil leak, nothing. I have used remote filters, oil cooler, additional oil pumps, sampling kits you name it. And I will not use them again if there is no reason to. I do not believe that Cummins cut corners to save a dollar or two on their oiling system. Nor do I believe you think that either, if so, why would you have bought a Cummins? I would not have if I thought they cut corners, and no one else would have either. Cummins did not get the reputation they have by cutting corners. I am very comfortable with the system Cummins supplied when I purchased my truck. I use a quality oil and change it and it's filter often, that in my mind is sufficient.



When I am out and about in my truck, I do not want to worry about anything. That would include oil fittings and lines not supplied by the OEM.

Have you done any BOMBing to your truck????? The aftermarket power upgrades would fall in the same catagory as the remote oil filters. . correct??? If this is the case... the power that our trucks had from the factory should be fine for what the truck was rated to do... right???

I do agree overkill is better. . Oil changes every 2k is great... but like everything else that we do to our trucks. . we as truck owners try to do a wee bit better with each modification. Whether it be cam plate,breathers,injectors,oil fitlers and down to the brake pads that we buy... we still work toward a better running truck.

And it also comes down to who writes the check for the aftermarket stuff...

rparlaman, I added the single Amsoil bypass system to my truck a few years ago. I then began running their oil and sampling to ensure that there wasn't anything going on in the engine that I wouldn't be able to see by looking at the oil as it drained out during a change.



I used the Amsoil remote bracket and filter and return fitting that is threaded into the oil fill tube. This way I can check the bypass filter flow so I don't change it unneccessarily. I can also easily remove the line up from the filter at this point to do an oil sample. I did take string (or vacuum hose or something, it was almost 5 years ago) to get a hose length and then I had some steel braided hoses made up.



I mounted the filter on the backside of the crossmember under the radiator horizontally so it won't get damaged by road debris. This system has saved me a ton of time and money by not changing oil until necessary.

Y-not, the stock oil system *is* perfectly adequate--but you overlook one reason for getting a bypass oil filter, and that's to lengthen the time between oil changes.



You mention that you believe in maintenance overkill, so just for grins I'll translate that to mean 3000 mile oil changes. For those of us who put lots of miles on our trucks, weekly oil changes would get pretty old. A great example was my last trip down from Alaska--I averaged somewhere between 700 and 800 miles per day. That would mean I'd be changing my oil every *four* days! Even if you extend your oil changes to every 6000 miles, that's still a lot of oil changes. That's when bypass oil filters start looking pretty good.



I was looking at the Gulf Coast Filter O-1 for my 1992. Not only is it a great bypass filter, but it also adds about a gallon and a half of capacity to the oil system.



I don't put nearly the miles on my truck as I did before I got married, so for me it doesn't pay to get a bypass oil filter. For some, however, it easily could.
