Got started on the mockup of my Oil filter bypass system for the NHC250. Going with a Baldwin 1308 base and a LuberFiner LFP777XL 3 micron filter. I will be mounting the filter base on the frame near the fuel filter canister. I am going to T into the oil lines that run up to the pump. I have a T fitting that will go into the pipe 45 degree bend under the pump and allow me to screw the JIC fitting into it. I am going to go with a -4 or - 6 JIC fitting on the T. The base has a 3/8" NPT inlet/Outlet. This will be either a -4 or -6 JIC fitting adapted to the pipe as well. I am probably going replace the drainplug with a fitting that has a JIC on the reverse side. Allowing the pump to pull oil from the pan into the bypass filter without it going thru the metal screen in the pan that protects the pump.
This will require the bypass filter to be replaced every 3,000 to 5,000miles or 100 hours. The normal oil filter at 5,000 to 7,500 miles or 200 hours and the oil at 25,000 to 30,000 miles. This will also depend on my oil analysis I am going to have after 10,000 miles of the system install.I just sent one off after 7,500 miles on Rotella and a B96SS filter being using. Also varies on oil burned. Current engine hours is 980. I am sure not many people here can reap the benefits of it but with the amount of mileage I do. I can go thru 7,500miles in 2 weeks if I choose to. I am about to go from Texarkana to Phoenix and back to Texarkana to Las Vegas. Then some very extended hauls to the port of Houston.
I will have about $140 into everything time I get done I am figuring. The base mount is around $40, Filter is $20, and all the other lines and fittings I will need. But it will save me from having to buy Rotella and a filter every 7,500 miles.
The following pictures are an 855 engine after it dropped a valve. The oil had been changed every 800 hours. Yes 800 hours for the 2years prior to being torn apart. None of these parts have been cleaned.
There are a lot of hard core rock crawklers and cool 4x4s in my area because I live relatively close to the Rubicon trail and I got some horn honking and thumbs up from a guy in a cool toyota rock crawler while I was backing in for the hook up. I started off small with a couple along my driveway, just idled them out.
