Bypass Oil Filter Systems

[dieseldavem]

I've been looking over bypass oil filter systems (kidney loop with 2 micron filter) for my 6.0. I've seen one design which tees into the oil pressure sending unit and returns oil to the fill cap and I've seen another that taps into the center of the oil filter cap and returns via the filler cap. The Amsoil stuff looks good (anodized aluminum) but is pricey (approx $300 for filter,oil filter cap, and oil filler cap).

Does anyone have any experience with these systems or possibly other options? I've seen the bulletproof diesel option but chose not to pursue that option due to cost. Thanks in advance for any info.

NUC motorsports also does the 6.0L oil bypass.

I got their oil filter mount on ebay for $20 and the oil filter cap from NUC for $60. All the other stuff was local except the amsoil oil filter.

I like taping into the oil fill cap, it is cheap to replaces. I strongly suggest getting a new oil Fill cap, dont drill and tap into the OEM oil fill cap, it is not good fro that, there is not enough material. I got mine from Oreilly's auto parts. The after market cap is much better to drill and tap into for the oil that returns to the engine.

I have done one analysis on extended an extended interval.

Exactly, what he said. Use the amsoil filters but there is no need to get the amsoil kit and I recommend get the aftermarket oil fill and filter caps with the ports already threaded but you dont have to get them from amsoil. I dont do extended drain intervals, I just have it for piece of mind.

Do not tap into the OEM oil filter housing or OEM oil filter cap. The material is very thin on both. Especially the cap. For any one thinking of doing that, DONT.
Do it right and get an after market oil filter cap made with the port on the top.

I'm a fan of oil bypass systems, especially on a 6.0. I've got the bulletproof kit but there are other options as well as you already know. I don't extend my intervals either. Still change at 5k.

I pit a DIY Fleetgaurd 777 bypass on both my past 7.3's and I'm thinking I will put one on my 6.0. The 777 goes down to 5 micron I believe and adds several quarts to the system.
