'05 Avalanche 2500 8.1L

Just a tuner for engine mods, used for heavy towing.

Has the oem oil cooler in the radiator, appears to be leaking oil from one of the lines at a rubber to steel interface. Seems weird in a 4 year old 60k mile truck, but.....

Is there anyone out there who sells upgraded (steel braided?) lines with the proper fittings for a stock block/rad? If I did this I would also want to add an inline air to oil cooler (more cooling is better, especially if I decide to throw a cam or such at it). Any thing out there? I have googled, looked on Summit/Jegs, autozone, that sort of thing, but I suspect it would have to be a little more specific. I can't even find replacement lines online.


Thanks
