Has anyone put a by-pass filter on their truck. I have one for mine, and I was hoping someone knew where I could tap into the oil supply. It should be a pretty easy install at least with my PSD it was. I had a place to tap into the oil right above the oil filter. If I remember right you just have to remove the two plugs and connect. Anyone out there have one on or installed one? Thanks

 

You mean to relocate the filter? I haven't done it but I know someone on here has.
I take it you are serving over there, thanks.

 

Yes I was serving overseas, but I just got back a month ago and I haven't change my location. I am now in the state Nevada.

With regards to my new project I am not trying to relocate my filter. Infact I will keep the same filter. I am just adding an extra filter that filters a lot more than standard filters. Its called a by-pass because its so slow it cant filter all the oil at once that is why you keep the original for the quick filtering and add the by-pass for the really indepth filtering. They say it keeps your oil so clean you only have to change the filters from then on. I will have to look into my engine books to find some more on ports. The Engine section in this forum said that we have some ports on each heads, but I will have to investigate. Thanks

 

Ok, for starters, there is no way a filter alone can keep you from ever needing n oil change. Even if it can remove all the impurities, the oil contains additives that keep the seals and rubber parts in good condition, Second off, what keeps the filter from removing oil additives? And third off, how does it remove dissolved minerals and acids? If oil can get through the filter, those things can too. If someone is telling you that it keeps your oil that clean, its just because they want you to buy it. What does the FCC say about this product?

I run full synthetic oils, which saves me time and money because I only have to change it every 15,000 - 20,000 miles. I just run a filter designed for extended intervals.

 

I was exagerating a little when I said I wont ever have to change the oil. Although I have read a lot of testimonials of people that have gone years without having to change thier oil. This is something I have read pretty indepth. The diesel guys have been using these systems for a long time now. Your oil gets the additives it needs when you add an extra quart or so because when you change the filter you lose some. Here is one of the producers I pulled up for you to read

AMSOIL - Ea By-Pass Oil Filters (EaBP)

Like it says if you send your oil in to be tested or analyized and its still good then you keep on using it. Its not bullet proof but its a far cry from the 3000 or even 5000 mile intervals with conventinal oil. The biggiest problem with the oil is it becoming contaminated not losing it ability to do its job, and I know there is material that can take minerals and acids out of oil while still letting the oil pass through. The absorbment material can be made for a particular substance. I will see if I can find some more information on this for everyone.

 

a bypass filter robs 10% of your oil flow and sends it back to the sump. it can not be used for engine lube. I think it would be better to save that money, use a good dyno oil and change every 5000 miles. i think thats the best way to get the crud out, to replace the oil.

 

I think using a good oil is a better bet, and you have to weigh the options carefully. For myself, a good top of the line synthetic is well worth the extra money. One vehicles that use conventional oil, when you look inside the oil filler cap, the metal is all carmel colored. On my vehicles that use synthetic, that metal is metal colored. Synthetics do a much better job of cleaning the engine, and keeping it clear, in part because regular oil does not want to absorb acids and dissolved minerals, or heavy hydrocarbons. Ester based compounds on the other hand, and naturally detergents in their own right, and will readily absorb those things. In fact, some of the additives used as cleaners in regular oil is what synthetic oil is practically made of.

Also who ever said you need to change regualr oil at 3,000 - 5,000 mile intervals. According to the owners manual on my van, Ford recommends 7500 mile intervals when you use an oil that meets their requirements. More than that is a waste of money unless you qualify or the extreme service intervals listed in the owners manual. RP and Mobil1 list their synthetics to last at least 15,000 under regular conditions, and Amsoil recommends 25,000. If you are running under the severe conditions in the manual, then you might have to replace it more often than that. The key I have found does lie in the filtration. Your filter must be able to last at least as long as the oil.

The filtration you speak of is in my opinion a good idea, though I doubt it will give you any real world advantage. Most of the damage to the engine that shortens its life occurs within the first few tenths of a second after it is first started. If you really wanted to do something to enhance the engines longevity, I would look into installing a kit to get oil pressure even before the oil pump turns over. There are kits that use a pressurized tank and a valve and solenoid to trigger the release of pressurized oil when triggered on my the start terminal. So you get oil pressure as soon as or before the starter really gets going, reducing the number on cause of engine wear. If you have a system like that, it should not matter what oil you use.

 

Here in the on-line owners manual for a 98 F-150 it states to change the oil every 5000 miles max.
