Greetings Folks,
A happy Father's Day to you with children,and if you feel that close to your truck,consider yourselves included as well.
I'm currently in the middle of a 230 motor "refreshing",and this would be a good time to address this issue.A friend of mine had broached the subject a few months ago,but he doesn't have any definite info,as myself.I did check past postings and came up with info on a swap to a spin on filter with part #'s.Thanks go out to MSeriesRebuild for that.However,I'd be interested in considering the full flow filtration method,and the pro's and con's members are aware of,or better,have actually experienced.
Fabrication willnot be an issue,as that is part of my vocation.Reliability is paramount as this is to be a runner.Cost is always a factor and will determine whether this can be done with the reliability(go with mods) or that reliability can't be met at that price(no go,stay stock,with maybe the spin on for convenience).
Any pertinent info will be most appreciated.Thanks folks,Chris.

I would also be interested in this. My oil seems to get dark really quickly. I am not sure of the cause, but I have good compression on all cylinders, or I did almost three years ago when I bought the truck. I am going to start running a higher grade oil with my next oil change, which is coming up soon

This topic comes up frequently on the early Jeep boards.

Scroll to the second post which has an excellent summation of the differences between a full flow and bypass. In short you won't gain much by converting. In regards to color, L heads are inefficient at burning gasoline and will darken oil much quicker than a modern engine.

Back in the old days, your oil always got dirty, that was part of it's function. Modern vehicles are so clean, the oil looks almost the same coming out as it did when it was new. Be thankful your oil looks dirty, it means it's doing it's job. I'd be more worried if my M's oil stayed clean!

Hey Fellas,Thanks for the replies thus far.WyoWilly,I went to the link,thank you for posting it.Good diagrams,very well presented.And yes Warren,our older vehicle's oil does get dirty faster than the newer engines,and that's because the machining technology has come so far that the tolerances have been reduced to a degree that allows those tight clearances that preclude the amount of combustion blow-by that the old engines had almost new.You have to run 5W-20 oil to flow through those tight clearances.That part's great.The utter complexity of the opererating system definitely is not.I still prefer my older Spark/Fuel/Compression troubleshootable motor!Not to mention room for a small sofa under the hood.
