OK, got my USED Gulf Coast Bypass Filter... this is the "0-1" model you can see at Model 0-1 Bypass Oil Filter . I figured I would tear this thing apart and take some pictures of the pieces so people know what parts make up a Gulf Coast 0-1.

Even though it's used, it seems in good shape... it isn't as light as I would have expected... the outside is 3/16" casing and plate, and the brackets are 1. 5"x1. 5"x3/16" angle. This unit weighed 27 pounds to ship...

This thing is fairly BIG... it doesn't surprise me that there aren't many ran on pickup trucks... you would need a lot of room.

An Amsoil EaBP-110 11-inch long bypass element for comparison... what the GCF will replace...

I'm going to have to do some head scratching to find a "good" mounting spot. May simply make some sandwich brackets on the frame... may make a bracket and suspend it from the bed floor.

OK, so now that we have a size... here is the guts...

The endcap is tightened hand-tight... spins off by hand, there is a gasket/seal in the groove on the lid.

The spring thing must keep the element shoved to one end... it also serves as a handle to pull the element out of the housing...

Here are the guts removed... note the plastic centering ring has a tapered center to plug the TP roll...

And here is the ends... and the orifice which is pretty small... appears around 1/16" (I believe this is actually 5/64" after reading).

Hopefully this helps someone looking at the GC filters...

Interesting blurb from the Gulf Coast site:



BY PASS OIL FILTERS



Gulf Coast Filters has over 20 years experience dealing with bypass oil filtration in the trucking industry. We have spent thousands of hours monitoring oil analysis reports and helping our customers achieve the maximum life out of their engines. The secret to longer engine life and extended oil change intervals is pretty simple, keep the oil in new or near new quality at all times. Factory oil filters are not designed to purify the oil but mainly to filter all the oil at a high rate before it gets to the engine, and by having such a high flow rate is unable to trap the microscopic particles that enter the oil. The Gulf Coast Filter is a bypass filter and cleans the oil at only 2 quarts a minute flow rate allowing the microscopic particles to become trapped in the dense element. The element also removes moisture, the key ingredient for acid. The additives in your oil are there to combat the contamination and hold it in suspension until the oil is changed. The Gulf Coast Filter removes the majority of microscopic contamination and therefore your additives have little to combat against and are not depleted. When you change the Gulf Coast Filter you will add new make up oil to an already clean sump of oil that insures your oil is within new to near new oil quality guidelines at all times. Where's the proof? Gulf Coast Filters tracked a 1990 Peterbilt with a 425 HP Series 60 Detroit for over 1 million miles with only 2 oil changes and no overhaul. The first oil change was at 19,000 miles (break-in); the second was at 250,000 when a leaking oil pan gasket was replaced. One of our customers, Pepsi Cola of Gulfport, MS has been running Gulf Coast Filters for over 20 years on their fleet while not changing oil and getting longer life from their engines. Our goal at Gulf Coast Filters is very simple, save our customers an average of 70% on oil changes and allow them to run their engine many more miles between overhauls. Gulf Coast Filters offers an oil analysis program to our customers in which we keep a file and monitor your oil samples for you giving you the peace of mind that you know what is going on inside your expensive engine. All Gulf Coast Filters filtration units carry a lifetime warranty for the original user. Gulf Coast Filters also offers a full 100% satisfaction guarantee on up to 6 units for all our filtration products.



Their written guarantee make it sound like they have pretty good faith in their product!



Steve, is that element a tight fit into the canister - if not, what keeps oil from flowing between the canister wall and the element?



A suggestion, for our application, I'd put a small enough flow restriction to allow about a quart per minute - on my Frantz, that's 1/8 inch...



(EDIT) I see your comment on the supplied restriction - that should work just fine for the Cummins in our trucks!
 
YUP - size-wise, that's a serious filter - and as you said, understandable why not many trucks in our class seem to run them... :eek: :D


And to think I actually considered a GCF 0-2, which take TWO rolls of paper towels... :eek: I probably would have really had to look for a mounting spot...

I'm probably going to look like a nut at the grocery store measuring rolls of paper towels. The overall impression of this thing is pure overkill... just the shear weight of this thing says "industrial"...

I'll probably paint the lid (where it's rusted) and clean it up (shipped pretty dirt) and then figure out how to mount it. The more I think about it, I'll probably mount it under the bed, between the frame rails. As easy as the filter is to remove/service, placement isn't a big concern. (EDIT: just bought 55 feet of new 1/4" hydraulic hose to replumb my bypass... limitless mounting possiblilties!)

The element fits pretty tightly in the body. I don't think the oil would be able to channel along the outside... you need to twist it in/out.



As noted, the thing is built way overkill... obviously made for an over-the-road truck.

I looked under the truck tonight. There are two locations that are suitable... both would mount the filter horizontal, not that orientation poses any problem...



The first is in the same place my Amsoil unit is mounted... outside the framerail, in front of the rear tire. It will require bolting it to the bed crossmember with one end of the brackets and making a spacer for the other ends, hopefully tilting the unit slightly down. This would put it up high out of harm's way short anything thrown from the tires... it would also be easy to access for filter changes...



The other place is yet again mounted to the bed underside, almost the same location as above, only inside the framerails, next to the fuel tank. I only see one issue and that is driveshaft interference. But I have a full 2" of clearance at the transfercase end, and that "end" doesn't move. And again, this would make for somewhat easy filter changes and would definately keep things out of harm's way...



I like outside the framerail the best myself... the only drawback is that it will require pulling the Amsoil unit off before I can mount the GCF, but that would need done sometime anyway... it doesn't really matter where I mount it since I will be using new hoses anyway...



I also think I'm going to buy a few GCF filter elements to get a "feel" for them... see how dense they are... you know, if they are squeezable like a roll of paper towels or solid like a roll of paper...

So I guess that the filter housing holds six quarts of oil, as noted in this paragraph on the GCF website:



"Although Gulf Coast doesn’t refer to their filter change an oil change, the fact remains that when you replace their filter and add the make-up oil, about 6-quarts, you are adding lots of fresh oil to the system. "



At first, I was thinking, "Holy crap! Six quarts every 10,000 miles, but then I realized that you're not doing an oil change, just adding, so I guess the cost benefit IS there.



The only thing that bugs me about their website is that I could not find any pricing for the O-1 or for O-1 filter replacements.

One thing you also got to keep in mind that is while 6 quarts of oil seems like a lot of oil in a 3-gallon sump, the target consumer is running upwards of 30-gallon sumps and probably adding a gallon of oil every 3k miles or so... puts it in a little better perspective. 6-quarts to them is basically nothing.

So, with the price of an individual filter@ $16. 73 per ($100. 40/6pk) and Shell Rotella 15W40@ roughly $11. 95/gal, you're spending about $34. 65 every 10,000 miles or about $44. 15 at the 25,000 mile mark (Stratapore filter from Geno's@ $9. 50); I would do it @ 20,000 miles, though. Compared to the $85 my dealer charges me every 3,500 miles for an oil change, I'd say that this is definitely something all of us should be doing to our trucks. Thanks for the EBay link, steved.

And if you buy rolls of Paper Towels (the guy I bought this from indicated that Scotts "mega-rolls" worked the best), you are spending about $2/filter.



All the GCF element is, is a roll of paper media, similar to a roll of paper towels. How dense it is, I don't know. But I intend on buying a few to see if they are similar to paper towels...



IIRC, didn't they say somewhere you could go 500 hour changes?? The 10k changes were based on an over-the-road truck. I can't remember... I've looked at too many bypass filter systems lately to keep them all straight. I know that a UOA would probably be best at 10k and 20k... then base intervals from that.



steved
 
I don't recall seeing the 500hr interval change, but that doesn't meant that it wasn't there. I had, I think, about 25,000 miles on my '05 when I hit 500hrs. Not to get off the subject, but can you check the clock on the 24V motors like you can on the 3rd gens?

I might be dreaming that 500hr change interval...



I couldn't check my hours on my 04. 5 last night... seems a hit and miss option. I'm not sure about the others... I was going to install an hour meter, but then decide that mileage is easier and "close enough".



I mean if you take some of the average miles per hour generated duiring that discussion, most were around 35mph. Ok, the recommended 15k OCI for a 3rd gen would mean some guys could have roughly 430 hours on the oil (15000 miles/35miles per hour). I still run 10k OCIs with the Amsoil with an ok UOA... might stretch out to 15k OCIs on the GCF.

I have been reading the Frantz TP thread with much interest. I am looking for some form of By-pass filtration, but like you I would prefer element changes less often than 2000 to 2500 miles. The GCF looks like a good option. How is your search for a suitable Paper Towel going? The photos of the Gulf Coast Filter dimensions were very helpful, I was under my truck yesterday looking for a spot to put one. I hope you will post some pictures of your install when complete? I was also wondering on your old Amsoil unit were you using the Oil fill cap for your return location, or some other point?



Paul
 
I haven't even had time to look for a filter... the GCF probably won't get installed until June sometime...

I am returning the oil to the oil fill cap...

I actually had the GCF under the truck the other day... the best place IMO, is outside the frame, under the bed.

i was just at the gulf coast site and emailed to see if the 01jr would work with are trucks it is way smaller and may be aesier to mount . im not as concerned about the extended drains as i am catching the smaller particles i guess we will see what they say

If you want something like that, you have more options... Frantz, motorguard, and oilguard also make smaller units like that. I believe someone had a motorguard (uses TP) and an oilguard in the classifieds for sale...
