Frantz Bypass Oil Filter System - Thoughts?

[PetroleumJunkie412]

So it turns out the 4.0l SOHC is a sonofabitch to put an oil cooler on without a oil filter relocation kit.

So while trawling the summit catalog, i found this:

Bypass Filter System | Enhanced Oil Filtration

The Frantz Filter Basic Kit contains parts to fit most applications. It does not include fittings or hose. Select the products menu above to see if a specific kit is available for your application. The Basic Kit Includes: Base & Polished Canister Mounting Bracket & Hardware Pull Ring &...

Apparently it is a 1 micron filter that.... blah blah blah most of you probably know what a bypass system is.

If not, google/youtube/@Curious Hound is your friend.


Am I crazy for the following idea:

Instead of risking my lubrication system by building a convoluted oil filter relocation system with a thermostat, etc. to instead just use this filter system to run an oil cooler?

Granted, it only siphons ~10% of the total oil out of the system for the bypass filter, but the idea is to install the bypass on the oil pressure sensor line, and run the returns out in front of the AC condenser on a small tube and fin cooler before returning it into the valve covers? The only drawback I can see is no thermostatic control, but this truck does not see cold weather use, and its only 10% of the oil supply.

I dont know. I'm probably overthinking stuff, as usual.

I know @gw33gp runs a bypass oil system on his 4.0L SOHC. I know he's sold on the system in general. Not sure but he may have something to add here.

Did Explorers get an oil cooler?

I know they did on the 5.0's.

Apparently, yes.

Didn't know that.

Interesting looking bugger. Not sure if it would fit on the ranger.

AFAIK they are pretty much the same engine bay.

I looked over the Ford unit.

I hate it.

those are coolant lines. it basically sandwiches a coolant coil between the block & filter.
a similar cooler was used on 89-95 Taurus SHOs with the 3.0 & 3.2 engines.

check out remote kits for older big block Fords.

Hey other PJ!

Well that makes a lot more sense. I figured it was some sort of convoluted ford sandwich plate. Now I see it's just one more place to mix oil and coolant together in a Cologne engine.

@PetroleumJunkie412

part of my stash in the basement, been there since the late 80s?
it sends the oil out to a cooler then returns and goes thru the filter.

I have one similar here... issue with the SOHC is thwres nowhere to squeeze a sandwich plate between the manifold and the frame. It's a precise hole just big enough for your fingers and a filter. Cramped under there tbh.

I tried a few years ago to do it with Amazon parts, but couldn't clear the manifold with a mishimoto thermostatic plate. Only solution I came to back them was a total relocation. Hence the idea with the bypass, would avoid a filter relocation, gain a cooler, and a bypass as a bonus. Idk if 10% of the oil being cooled will amount to a healthy pee in the ocean, but I digress.

I'll crawl under when I can to get a photo.

I don't really think adding however many more places to leak and risk a bleed out is worth cooling the oil a little bit.

Ford has a bigger R&D department than I do and they felt it was worthy... however mine has been fine without it.

I think the bypass with a cooler may be the best option. Going to dig into the scrap SOHC I gutted out of a parts truck to see where best to run the return line. Their Dodge kit runs it through the filler cap in the valve cover. Not sure where to run mine yet; I don't think there's enough clearance between the oil fill cap and the hood for a fitting.

Plenty of real estate in front of the condenser for everything - bypass filter housing, cooler, etc. About the only place on this truck that's roomy.

Only reason I'm doing any of this is the blower... it'll probably be fine without an oil cooler, but why take the risk?

Can you add a fitting to the overflow jug?

Once the heads lift its all going to be together anyway...

I don't think the 4.90 SOHC engine needs an oil cooler. I have run mine hard on and off-road in some of the hottest desert conditions the West has to offer. I also have towed my race car all over the country. It now has 312K miles on and is still running strong.

I think a lot of that has to do with the micron bypass filter. I used it to run extended oil change intervals of 20K miles with synthetic oil. If you want to add an oil cooler, that is up to you. I don't know if a bypass system flows enough oil to make much difference, but it will help a little. I suppose the longer retention time in the cooler would help more.

The Frantz bypass system has a decent reputation. It filters down to 2 microns as most bypass systems do. I got the source of my oil by putting a tee on the oil pressure sensor port. The return goes back to the pan. A fitting was supplied with my bypass system that taps into the oil pan below the oil level. I have never had a problem with it.

I installed an Insane Diesel bypass (expensive compared to Frantz) on my Bronco 2.7L EcoBoost engine. Again, I installed a tee at the oil pressure sensor port but use their oil filler cap for the return. I used the Insane Diesel filter because it was the only one, I could find, that was rated at a true 1 micron. I am not going to run an extended oil change interval this time because the turbos will expose the oil briefly to high temperatures. The Bronco does have an oil cooler to help keep the oil from overheating from the factory. I feel the 1-micron filtration will extend the life of the turbo bearings.

What brand bypass system did you go with?
