Of course the cost would be WAY more than an install of a drain plug, but for me it'd be worth not having to screw around with drain plug oil leaks.
The oil pan on the Duramax is multiple pieces. The one with the drain plug is the lower and only has vertical bolts. The upper pan (the one that goes to the front) requires removing the transmission and possibly the flywheel as the oil pan as it has horizontal bolts into it from the back of the engine. I got lucky when I had to change the rod in mine and found a socket that fit between the flywheel teeth to pull the bolts.

Great job man.

I've installed the BMK27 and PPE flat pan on my LML. Best thing I've done as far as longevity and feel good maintenance has gone. Filters are expensive, but 1 oil change a year I can handle the cost.

Are there any aftermarket filter options for this unit? I know Baldwin makes bypass oil filters that are nearly a quarter of the price of the EABP100 bypass filter, but not sure if they are compatible.

No idea. There probably are. But for one oil change a year I'll stick with Amsoil.

Great job of the installation.....

However, am I correct in saying that you've only used ONE of the Amsoil brackets to hold the head unit to your own thick mounting plate?

I realize that your set-up was older and in storage for a few years, so maybe Amsoil didn't originally supply the TWO brackets at that time.

They do now....and they HIGHLY RECOMMEND that both brackets be used to hold the head unit. There is a heck of a lot of weight on the 90 degree factory bracket when those 2 filters are full.

You can imagine, just by looking at it, that that bracket will eventually fail. The addition of the second bracket, that bolts onto the top will greatly relieve the stress on that lower bracket.

I think Amsoil changed their bracket set-up because some were breaking, causing catastrophic loss of oil. The one you have is shaped like an hour-glass and is designed to only be used on the under side of the head unit. The current/revised brackets are different and MUCH stronger. I strongly suggest you consider getting the top bracket to add to you existing one.

Yes, that's correct. I used one bracket and it was the one that came with the unit. Both filters hold a total of 1.5 - 1.75 quarts of oil. With the weight of the oil, filters, and system itself, there is a fair amount of weight hanging there, but it seems like the Amsoil bracket is pretty stiff. I'll have to call Amsoil and find out why they went with different mounting brackets.

So, here's the latest update. The weather warmed up, the monsoon set in and melted all the snow and washed away all the salt on the roads. I had to get my 5th wheel over to the dealer for some warranty work, so I pulled the truck out of winter storage, coupled up and took it for a 220mi round trip road trip. I took my temp gun with me to get some readings. I'm definitely changing the hoses out on my system. I was getting temp readings off the filter adapter at 170*, the hoses were in the 130* mark, and the filters were in the 140* range. Being it was a mild 50* outside, I can just imagine the temps are gonna climb when summer gets here.
As far as the rest of it, with these Michigan roads totally sucking right now, we managed to hit some pretty bad spots and flexed the suspension of the truck pretty well. I was a little worried the front torsion bar would make contact with the filter, or something would spring a leak, etc... Needless to say, everything worked flawlessly. I got home and crawled under the truck for some inspection and found some oil on the torsion bar, but it was some residual from when I converted all this over. Factory filter placement and design is pretty poor. Fords are mounted vertical and nothing in the way and same with the Cummins. But I don't have to worry about it anymore. As far as the oil visually being any more clean with the new filter system installed, I didn't check. I'll try to remember when I pull it back out to go and pick up the trailer.

Sorry about the slow response. I've been pretty sick but better now. I'll go out and get some decent pictures tomorrow and get them posted. Still a little weak but rolling around on the ground is easy!

Here's an update... this setup lasted until July 8th last year. I was towing my 44' 5th wheel home and got within a mile and all of the sudden the dash lit up and alarm chimes going off like a 747 is going to crash. I looked down and saw low oil pressure on the DIC. I slammed the key off as fast as I could and watched $150 of amsoil pour out in the center of the road for a half mile as I coasted into my subdivision. I got the rig stopped in front of a neighbors house where a lake of oil started to form on the road. What a God [email protected] mess,... truck, trailer, road...
When I installed the kit I got the hose from an old guy that runs a reputable hose and fitting shop here locally. He said this hose is such a SOB to put on that I dont need clamps because it wont come off. He said they've installed this many times on machines in local factories with no issues. Yeah, well, it happened. And it almost cost an engine. What happened is the 90* adjustable swivel fitting on the side of the filter adapter came loose and turned downward which spit the hose off it that wasn't supposed to ever come off. I ended taking all this off and putting an AC filter back on it and filled it back up with oil. It took almost 2 gallons. I fired it up and instant oil pressure and no funny noises.
I'm gonna put it back on, but I'm really gun shy. So I'm doubling up on everything. Anything with threads is getting threadlock, with the exception of the filters of course. Everything is getting a little extra torque put to it. The hoses are getting replaced with the same hose that comes in the kit from amsoil. Squeeze clamps are going on instead of screw style hose clamps. And if there is enough room on the fittings I'm doubling up on the clamps too. And finally I'm throwing down a line of Markal security paint for quick, easy visual inspection.

When I did my amsoil kit over 150k miles back, it came with a bitch of a fitting to put on the hose. You put the outer sleeve on over the hose, then thread the hose onto the fitting, then put the outer sleeve onto the fitting.

Check out section C on page 2 of the instructions. https://www.amsoil.com/products/bypa...MK27_BP258.pdf I think that's what mine looked like. Thus far no leaks. I think that was about 13 years ago.
