I was wondering if the lines I can buy at the parts store will last any time at all. I think my lines are leaking at the crimp there the rubber hose starts. Somewhere I thought I read on here that the new ones are not much better as far as leaking. They were not easy to get out so I would like to do this only once.

 

i was looking around to do the same thing,and i think i might end up making my own. i found a place called lubrication specialist and they have a kit. some of the sponsors here might a kit also,but i haven't gotten that far. i also read somewhere that you can cut off the crimped part and put a flare on the metal part and slip the hose with 2 clamps on each end.i might go this route for now.

 

yeah lubrication specialist and pmdcable.com both have good oil cooler line kits. i got pmdcable one and i enjoy it very much. a year its been on and no leaks so far

 

do like i did i kept my oil cooler put new fittings in it and had new lines made it was lot cheaper to do

 

just put plugs in and throw the factory oil cooler lines away thats what the radiators job is to cool down the pickup. cummins dont have oil cooler lines

 

i wouldn't throw away oil cooler on 6.5 it needs it

 

two totally different engine designs with different oiling systems. a 6.5 needs an oil cooler

 

I just took them apart and put new hose in them with double clamps at each end got that idea from ricansdiesel . started and ran for about twenty minutes no leaks have not run down road yet more pressure may make it leak ?? well see

 

hi i've just bought a gmc 6.5 td and i've got an oil leak at the same spot, the oil lines from the oil cooler. Im looking for the best way to replace / repair it. does somebody have some tips?

 

I have the same problem, I'm gonna take them to a local hydraulic shop and get new made. It really is a bad design by chevy to seal them up the way they do. My Hydraulic shop is going to make them like a O-ring sealed hyraulic fitting, the oring seals on the out side on flange of fitting. May cost more but garaunteed to never leak.
