I just had changed the oil and put a fram on it but thats when i noticed the oil pressure wasent any god so i put anothe filter on and i beleive its a luber finer ,some thing like that.I no the oil cooling lines are not connected for some reason,was like that when i bought the truck.Ill take a better look at underneath the truck tomorrow,thats what i was thinking i mite have to just take the motor mounts off and raise it up a couple inches to make room to slide the pan out.Guess ill start with that ,,thanx again Crazy ill keep you posted .

So in all your guys opinion which is the best filter to buy when I change the oil. Mapleleafpete, let me know what you come up with on getting your pan off, how much trouble it is, and also where are the oil cooler lines so i can make sure mine are hooked up.

Where i live were limited to what we can get for filters,one shop in town so we gotta buy what he sells unless we go out of town witch is a drag.I havent looked under the truck yet Ben,im to depressed to tell you the truth,.Been doing a ton of reading and could be a lot of things like oil pump,cam bearings or just a tired motor witch i doubt.So im thinking cam bearings or oil pump,been looking around for a low milage 6.5 but what if i get one and im in the same boat,junk again!!! So theres allways rebuilding it,rings, bearings,cam bearings.Gonna look at prices for this,,Crazy do you no if i can change the cam bearings with the motor in the truck ? I no ill have to take the grill and stuff off to get the cam out and the tool to get the bearings in and out but was wondering if this was possible.Still havent confronted the p!@#k who sold me the truck yet but thats coming,.

Ill third that with the wife, mine hates my truck and i swear I'll be a sleeping on the couch till I die if anything major goes wrong with this truck, I have a habit of forgeting the things she needs done and just remembering to work on my truck, maybe its not forgetting hehehe! Let me know what you come up with on the oil pump if you change yours out, i noticed mine had a lot of thick sludge in the top intake when I took it off and when it warms up I'll take it back off and clean it out all the way. Just trying to get it where I can drive it to keep it from sitting so long while its cold. I do think its getting time to replace the glow plugs and those things aren't cheap either, mine has white smoke when i start it on a cold day but that's another thread.
