Bypass oil filter, fuel water seperator?

All I run is two cat filters one on the engine and one on the frame. The frame mount does not have the pass valves affecting it like every engine uses. Microns don't mean nothing to me in that aspect. Every engine has bypass valves that work when first start cold until oil warms and thins out. With a second filter plumbed in oil rail it is always filtering a percentage of your oil. Any bypass filter only filters a certain percent of your oil.

 

Most of the post 2008 engines with DPF/DEF systems already have a bypass filter on them, hence the extended oil change interval, 50,000 miles recommended by the various manufacturers. The EGR engines prior to that did not, and they were the ones with the soot problems.
I am in the camp of oil is cheap. I do my own oil changes, analysis indicated 20 thousand miles in my service, buy the stuff by the barrel, and the side benefit is it forces me to crawl all over and under the tractor regularly, finding things to fix before a failure. That PM program has worked for me for 40+ years.

 

My 2013 Volvo had soot problems along with the 2014 volvos we have with soot loading on the rocker shafts and taking out cam lobes. Each person has their own preference on maintenance, but I'm wouldn't hesitate to spend $350 on the heavy duty filtration system my dad runs, especially if I could extend oil drain intervals to much longer than normal and have high efficiency filtering for two microns for up to 120k miles as oil samples show.

 

I think that soot ####s up more than just the cams. If someone gave you a used head with no manifolds on it I bet you'd have to take a good look to tell which ports were intake and which were exhaust. All that soot being sucked back into the engine I'd imagine shortens the life of the liners and pistons too.

 

Yes.... But it's because of what the soot actually does to the oil..... It thickens it to the point that flow dramatically decreases and the lack of lubrication kills everything..... Cams and turbos first...
Biggest problem is running 15-40 and using extended intervals.
ALL D13 motors have come with 10-30 for years from the factory but guys think changing to 15-40 is better... It's not!

My old 07' with D16 had bypass as well.... (The middle filter)
Change it sooner and it'll keep filtering the soot... That helps too...
