What is the sole purpose of an oil bypass set up? I see them in guys galleries and just not sure of the benefit of these units.

Are they used to easily change the filter or what?

I'm still a major newbie here so go easy on me.

 

Extended oil drain intervals and piece of mind of OTR rigs.

Most people running bypass have two filters and change primary around 12.5 and both at 25k. They also conduct oil analysis on a regular basis.

 

Oil-Bypass system is a way to antelitcally clean your oil without having to change it. Basically we send in oil samples to have it check to see if it is clean. We then change the oil filter and or the by-pass filter if needed. We do this at the normal oil change interval. If the oil is G to G then we just add the makeup oil if needed and keep on driving. The By-Pass filter usually filters down to about 5 microns or less so you cannot use it as a normal filter becasue of flow.
Most of use that run this type of system are alos running full synthetic oil. Yes it does cost alot but in the long run you save money.

 

So how do the flows work on these things? It's called a by-pass, so then you can switch the flows rights? A by-pass to me means you can alter the flow around something for a reason. You say that you don't run the oil through the bypass filter as a normal filter because of flow, so then when does the oil run through that filter? I'm assuming the black filter is the 5 micron by-pass filter?

Just from the pictures, it looks as if the oil enters the by-pass filter first, carrys on into the regular filter and then out. The top plate I would think is removed so that you can isolate the regular filter so that it can be changed and sample taken.?

 

bypass just allows a small amount of oil to go thru the bypass filter to clean it really well and returns it to the oilpan. the normal filter does the bulk of the filtering for the engine lubrication. A bypass filter cannot flow enough oil to keep the engine lubed because of the 5 micron or less filter, that is why it is called a bypass filter.

 

Where do you guys mount the dual bypass filters on the 3rd generation trucks? I've been looking at mine and there does not seem to be a lot of room.

 

Ram in Texas - I suggest contacting TDR member CPFF/John Strenkowski if you're looking for a mount. He has some awesome stuff, and is a really nice guy. He makes a billet mount as well as a billet oil filter adapter. He also offers pre-cut stainless steel braided hoses to fit the setup. Check my TDR reader's rigs for pics.

Thanks Lightman!

Do you have any contact info for John?

 

Sure do. 860 642 7033 . I believe that's his home phone, so please be respectful and call during reasonable hours.. Great guy. He goes to thunder in muncie as well so you can catch him there if you're going.

 

You may want to look-up Oilguard.com. They have a pretty interesting site with quite a few explanations of how their system works.

Basically, their system taps off the "full-flow filter" head (the mount where the stock, factory oil filter) mounts. If you look at your oil filter mount, you will see a threaded hole with a small plug in it. That's where the bypass filter gets its feed of oil from. The oil then runs through the bypass filter to a new oil fill cap, which is provided in the kit. The new oil fill cap, on top of the valve cover, is plumbed for a return line from the bypass filter. And that's how the oil gets back to the engine.

This is Oilguards way of plumbing their system. Other systems use other techniques.

Many of these systems install a small orofice (around 1/16") to reduce the oil flow to the bypass filter so that the full flow filter gets the vast majority of the oil flow. There may be only 1 quart per minute flowing through the bypass filter but, over time, the oil gets a good cleaning.

You may want to check "bob is the oil guy. com", and check out the forum dedicated to "bypass filters". There's a lot of information about a lot of different types of bypass filters. You will see the term "TP" filters which refers to filters that use Toilet Paper as a filtering media. They have been around for a long time and a lot of people swear by them. The thing I don't care for about the TP filters is that you have to change the "rolls" more frequently (about every 2000 miles). It gets to be more labor intensive & less convenient, to use.

Hope this helps.

BEWARE: If something goes wrong with your engine, with one of these filters on it, you could void your warranty. However, these systems DO seem to work well. I believe these systems have their greatest advantage if you are doing a lot of long haul driving and don't want the inconvenience of having to change your oil so frequently. In this case, synthetic oil is the way to go, also.

 

Typically sourcing the oil from an oil feed and feeding it back into the valve cover or oil fill area is the traditional method of installation when there are no better options. I personally don't know how a cummins reacts to oil being sprayed in the filler hole. I can tell you guys that in my Mercedes diesel, even when filling the oil, you are supposed to point the funnel toward the front of the car, so as not to dump oil down in specific parts of the valvetrain/timing chain etc. I personally prefer the amsoil setup , which is very easy. An adapter screws on where the stock oil filter threads - with an IN and OUT line - very easy to hook up to the IN and OUT line on the amsoil dual bypass filter head. Same concept here, 95% of the oil goes thru the full flow filter, with a small amount going to the bypass filter.

Buffalo is right when he says for most folks the benefit lies in the convenience and cost savings when they are used for extended drains. The math doesn't lie, they are cost effective. Some folks go the other route - and change their oil at the normal 7500/15000, and simply have it so their oil is super super clean all the time. Then there are always the folks that say the truck will go a million miles on dino oil and why bother. Different strokes as they say.... I love my bypass setup and my oil analysis results over my last 20k mile drain interval are great. Very similar to a stock truck with 7500 on the oil.

 

I have used the bypass filters for years, first on some farm tractors, now on my trucks. My first Dodge went over 416,000 miles using a bypass setup and extended oil changes. Never any engine lubrication problems. Used about a quart every 6k. My present truck now has over 225,000 miles on it and it has had the oil changed 5 times. 6, 12, 18,000 miles when I switched over to Amsoil, (I don't care what oil you use, it will work on any of them) The next time I changed was at 67k, my airbox came apart and the oil analysis showed high in silicon so I dumped it. The last time I changed the oil was at around 167k, the oil analysis said it was still good for continued use, but I decided 100k was enough. I change my full flow filter every 6000 miles and my bypass every 18000. I run an analysis about two weeks before I think I will be changing my bypass filter to make sure the oil is still good. I have never been told to change my oil because it was bad, just to change my filters a few times. Extended drain intervals make it a very cost efficent way to use synthetic oil. The miles I run, it is one less thing I have to worry about.

 

eb that is sweet you have that much mileage already on a 3rd gen!

 

What's the cost of the mount and billet cap from Mr. Strenkowski? I just got a bonus check and am going to go with the Amsoil bypass system & I really like the looks of his setup. Also, does Mr. Strenkowski view this forum often? I'd rather leave an email for him instead of cold calling out of the blue!!

 

Gumby - he's on TDR and his screen name is CPFF I believe. He doesn't email or get online much though. If you have issues 'cold calling' businesses during business hours, you might want to seek some socialization therapy

I'm not sure of the cost of the setup - but if you've ever tried mounting one elsewhere and heard the annoying hum that's associated, you would fork over whatever it costs to get the thing mounted to the block and cancel the noise. All of John's stuff is top notch, nicely cut in billet. The filter adapter is sweet.
