djbikeman is correct . also if you run the return to the fill cap you can check flow, all filters filter better the dirtyier they get, run the bmk 11 untill it clogs up you get the best filtering and is the most economic. on all of the rigs before we started doing this we just feel of the filter after a trip , if it is warm it is working

 

So, questions for those who are running a bypass oil filter:
1) Are you running synthetic?
2) What brand & weight of oil?
3) Now long of oil change interval are you running?
4) What does your oil analysis look like?

TIA

Yes

Hmm... I know I have read about a few guys with 03's having the CEL issue, so I don't know about that.

See answers inserted

 

can you tell a difference in the color of your oil using the 2-micron filter vs regular filter?
does anyone have a truck that smokes a lot and would normally have nasty black oil that can tell a difference by installing a bypass?
has anyone compared a amsoil bypass to a fs2500? i know they are more expensive, but are they any better?

 

we run delo 400 15w40, we sample the oil at the 20,000 mile filter change and let the analysis detirmine the change interval, i have a mix of amsoil , home made, frantz and modified large truck bypass filters in use each truck has a different oil change interval, the frantz works better than the others but due to the quick cloging we quit using them (lazy) one that we just came up with that looks like it will make it through several oil changes before cloging up is a luberfiner LF9750 the base is LMB451 just added a 0.070 orface in the fitting that screws into the cummins filter housing to slow the oil flow for our small motors. cant spell

 

They are both good by pass filters and filter the oil in the 2 micron range. The FS2500 cost a lot more then the Amsoil set up so it makes the Amsoil the most cost effective of the two.

 

On older motors yes you can tell, and I can tell on my gasser... but anything 04.5 and newer no you cant, but color is not an indication of oil life or contamination.

The Amsoil is much cheaper than the FS2500 and filters better, Amsoil is 2 microns absolute, FS2500 is 2.78 Absolute. So I would say they are not better.

 

Thanks, AH64 has a nice set up as well. To be honest Amsoil doesn't recommend the bypass to be mounted on the block, but the FASS systems are mounted in the same location as mine, so we'll see. Here's a couple more pic's of the bracket.



The dimensions are about 5"x 7" of 3/8" steel painted Hammered Black. 5" horizontal x 7" vertical. Oh, no extra hose.

 

tried to run dual remote amsoil bypas low oil pressure light would flash dinging etc i told amsoil then they came out with the bmk11 single filter and dumped it ontop of the head in the oil fill. stopped the low oil pressure crap when there was oil pressure but the little bal oil register in the unit couldnt register it only being a little lower then normal. so i now run the bmk11 and love it everytime i send in my oil anaysis in its still good so i change filters and continue using the oil fill to top off etc... sorry for the length

 

That is the beauty of the bypass systems and using synthetic oils---extended oil change intervals, better filtration, and longer engine life.

 

yep thats what I heard as well.


NICE JOB ON THE MOUNTING "ah64id" I like that set-up

 

Good idea to add a gusset on your bracket just to limit vibration as much as possible.

 

not really much help but no, Delo 400 CJ4 15w40, 5000 miles, never analysed

You might think it's crazy to still be dumping the oil at 5000 with the bypass but I've been kind of lazy and haven't done any analysis. Plus it's piece of mind with the lower TBN CJ4. As pricey as replacement filters are I like the idea others posted of leaving it on there until it clogs up. I do figure on having regular oil analysis and switching to syns on extended intervals maybe at 25 or 30K miles. I'm almost at 16K now.

 

Didnt you mean to say 3/16th? Looks good by the way.

I dont have my truck here but I dont remember seeing an inlet on top of the oil filter housing. Did you drill and tap it. Maybe I need to reread this post closer.

So by the looks of it can I just get the filter and filter housing and plumb one in and one out? I mean is there nothing else inline?

 

The oil filter cap is made by amsoil and has a swivel fitting in it, makes install a breeze, as well as sampling.

Yes, the filter is the only thing inline, there is no need for anything else. I do plan to add a sleeved oil filter cooler during summer months to aid in keeping the lube cool.
