Oil bypass on a 3.6

Just thought I'd post a few pics of my Frantz bypass. I put in a temp/pressure gauge a few weeks ago and though why not put in my old Frantz. Sure some of you will say they're not needed on a 3.6 but why not. it should keep my oil cleaner than the stock filter. Anyway it gives me the warm fuzzies knowing my oil is being filtered close to a micron

I didn't have anywhere good to mount the filter so the bumper seemed like a decent place. I don't mind the way it looks. The air flow during the summer should help keep the oil a little cooler. The oil is returned through a hollow pan bolt. Nothing to it (!)

Is this an oil catch can or an oil filter with a fully pressurized oil line going to it? If the former, it's just a waste. If the latter, seems like an excellent way to accidentally bump something, burst the oil line, and sieze your motor from no oil pressure (best case scenario) or set the rig on fire and having insurance deny your claim because the fire is your fault (worst case scenario.) Sorry brother, I definitely don't think this is needed, much less a good idea.

It's definitely interesting! I love the idea of more filtration. Normally I jus screw on the biggest filter I can with all the same specs instead tho. Bosch makes a huge one that fits with all of the same specs. This only works on the 3.8 though

OEM filters do a good job of filtering. Generally speaking, anything that makes it past a filter isn't large enough to damage anything. Ask anyone with a 300K mile civic. The cons of this mod FAR outweigh the pros.

That seems like a really....exposed locatation for an oil bypass. Might be time to get a bull bar or light bar some something to help protect it a bit.

Wow, that's REALLY an eye sore. I love the functionality. Like you, I'm obsessed with maintenance and longevity more than anything else on the Jeep.

Let's be real though... I'd be too uncomfortable by all the weird looks from people to ever have that on my wrangler!

But good job.

Sorry I'm out on this one too. An accident waiting to happen I'm afraid.
Is there nowhere safe under the hood to mount it. ??

Looks like something to make it easier for some punk to mess with the oil in my car. Nice idea but if that's the only mounting location I'd pass.

Man, you can filter oil to sub-micron specs if you want, but you'll do it at the cost of decreased flow and increased pressure.
A good oil filter balances flow and filtration efficiency. Go too far in either direction and you're risking problems.


edit: my bad....didn't see it was a Frantz setup. It'll clean your oil better...but as was stated above the location leaves much to be desired, for numerous reasons. Why not relocate it to a better-protected location?

I can reverse onto your car at 3 mph and take out that can, and leave you with no oil for the night.

I criticize placement, not filtration.

You need to learn a little more about how a oil bypass works For the rest of you I'll have to say this. I'm a friggin genius Not only that but I'm smart (!) No room under the hood. Don't feel like crawling under the Jeep to inspect/change the TP. The bumper is a good place. I can keep my eye on it. With all the sh$t some of you guys have hanging off your Jeep a little silver can seems pretty innocuous.

No worries about getting into an accident. Lets see what's behind the plastic grill ? Why it's a radiator. Nope....no worries in the least about the set up. I like it. It looks utilitarian, and it's functional.

No worries if most of you guys don't like it or get it. I do, and that's all that matters I guess.

You dont need an accident to damage that can, any retard backing out of the parking garage can damage it.
Between an accident and the radiator you have plenty of things, you have for one, the inner frame of the bumper, then you have the frame rails, then comes the steel frame of the body, then comes the radiator. Whats between a car and that can? air.

You put too much hope in other people being careful.

People mount onboard air and dual batteries under there I'm sure there is room for that can somewhere.

You posted it opening it up for the opinions of others and they are just giving it. Most people like me will prob find it ugly or a safety issue. I don't think people are against its function. I would personally rather have a winch there instead of that can but its your jeep so run it how you want,

I think most of you missed the point of this thread. I've demonstrated proof of concept. It's arbitrary where the filter is mounted. After first dismissing the filter on the bumper I reexamined it because I couldn't find a suitable place under the hood, and I didn't like putting it under the Jeep. The more I looked for a place besides the bumper, the more mounting it on the bumper started to make sense. It has a lot of advantages, and goes with a utilitarian theme. Isn't that what Jeeps are all about ?

The accident thing doesn't scare me. No minor bump is going to damage the filter or the 5000 psi steel braided hose. Any minor bump will hit the bumper not the filter. An accident that is forceful enough to damage the filter is an accident where the last thing I'm going to worry about is a damaged filter. I may over time relocate the filter but right now I want to monitor it for leaks and function. If it were in the engine compartment and started to leak it might take days before I would notice, and I'd have a big mess on my hands. On the bumper I can inspect it every time I get in or out of my Jeep. The oil cooling effect during the summer could also be a benefit.

So what I've offered is proof of concept. You want to add a oil bypass to your 3.6 ? Now you know it can be done, and it's completely reversible. That's all I was trying to get across. Mount the filter anywhere you see fit. Mine will stay on the bumper until if and when I find a better solution, but it's growing on me, so I'll probably leave it alone. During the winter I intend to insulate the filter to help keep the oil warm.

btw....I don't need a winch

I criticize both. There is zero added benefit of "cleaning" oil to that level. The funny thing is, that can void your engine warranty if anything happens, but not having one won't. You gain absolutely nothing filtering oil to less than 1 micron level except a lightened wallet. It's snakeoil I'm afraid. Im not bashing on the OP. This is more of an informational thread or others. I admire the OP for trying something, but some mods are just plain not worth it. Anytime you add oil lines, you lose pressure and gain vulnerability. Maybe on an F1 car, with tolerances tighter than Rosie Odonnel's grip on her cupcake, MAYBE 1micron filtration will help. On a production offroad vehicle? No chance.

I definately credit you for the proof of concept.

Now take it a step further and find a safe place under the hood to hide it. What about cutting an inner fender, near the rear of the fender, and tucking the oil thingy in this area?

For now, I think you should take what appears to be a tornado detection device to Oklahoma and help them out.

I have turbocharged many vehicles, as well as my s2000, so I know a thing or two about oil lines. While the line might be 5000psi (doesn't mean squat in puncture strength btw), the fittings are weak aluminum and can EASILY be ripped/vibrated to hell.

I don't intend to irritate you. You posted, I commented. Like I said, I appreciate and respect the effort. If it wasn't for people like you many things wouldn't come to fruition in the world of vehicle modifications. Having said that, some mods are a boom, some are a bust. It is your Jeep, and it is your money, so obviously no one is going to tell you what to do, including me. Sometimes for the good of the forum/people, things need to be criticized. If you can figure out how to filter the oil better without more plumbing, that would be an excellent solution. I have seen those lifetime surgical steel filters that claim to filter down to low micron counts, so retrofitting that might be a worthwhile solution, although I maintain, on a modern motor with modern oils, there will be no benefit. Having said all that, I will bow out of your thread, and once again applaud you for your efforts.

I'm looking at all those heavy brass fittings and the big sending unit sitting on top of it all. Is all that threaded into the factory plastic oil filter cover?
If you hit a couple of real jarring bumps, it'll break right off and pump oil all over the top of your engine.
I'm not trying to be an ass, but that's a plumber's nightmare and a definite weak spot unless I'm missing something.

I don't understand... Why install analog gauges and use toilet paper for filtration when everything is conveniently located in factory locations?

The last time I looked my EVIC had digital readouts for water, engine oil and transmission temps. The oil pressure and tire pressures are also digital.. we've come a long way with the use of modern sensors.

In the 70's I heard some truckers used toilet paper for filtration... never actually seen someone adopt this on a modern vehicle - much less an older vehicle. This Frantz company appears very old school.

Question:

Would this setup on the front bumper pass a state inspection?

Just curious.

until a chunk of retread or a large rock on the highway takes that thing out.

good concept, great idea, poor implementation.

If it were in another location, I think the comments would be a lot different. But right now, that seems like the worst possible location one can think of. Your oil filter is screwed into a plastic bumper on the front of the Jeep. I see grill guard installed, so why leave the oil filters so exposed to the elements (winter time snow, ice, salt), high winds (would it tear off on the highway?), road debris, or the random idiot (punk kid messing with it, or someone in a vehicle with a rear mounted spare bumping into it)?

Just found out the 2014's will have the option of the "super" EVIC....
