Excessive Blow By
If I have excessive blow by through the oil cap when I take it off. Can this be fixed by replacing all of the injectors? I also have white smoke coming out of the exhaust indicating an injector problem. I have replaced 3 and it seems that the truck runs better but should I keep replacing them or should I just trade the truck for another cummins?

Too much fuel will create ALOT of heat and burn a hole(s) in your piston(s). 236k really isn't a lot of miles for a cummins, really poor maintenance and abuse will have an affect on longevity. Also a poor quality air filter can allow dust particles to enter your engine and cause excessive cylinder wear, contributing to blow-by. If it were me, I would go for a rebuild.

You wont really know until the engine is torn down. smart money is on boring the cylinders, new rings, complete valve job etc. Ya really cant go wrong with a rebuild b/c that way you know your engine is fresh with no miles, and you will have piece of mind knowing that it is fresh. If ya bought another pre-owned cummins, you wont really know how that rig was treated, or if it was sold/traded-in due to mechanical issues or other problem(s).You may end up in the same situation that youre in now...or worse. Ya don't really know what youre gonna get. Its really a crap-shoot. If youre happy with your rig, and its been good to you, I personally would go with the rebuild. Its also cheaper than a new truck. But, its really up to you ultimately have to live with your decision. Cheers!

That depends what you plan to do with your rig such as race, sled pull, mild performance or just stock..ish. Stick with cummins parts, but you cant go wrong with studs for possible future "upgrades" (if ya get my drift). Im using ARP's in my rig, but my mods are rather conservative, as my goal was only to increase efficiency.
If this is your daily driver, then I wouldn't go crazy with it. Mild performance is more than plenty for. But if youre into rolling serious coal, creating tire smoke screens that would rival the military's best efforts, and blowing the doors off mustangs, vettes, vipers, then the sky and wallet is the limit. (not quite sure I answered your question)
