We have a 02 DSDP with a 3126 with 90,000 miles. We recently had a problems with 2 oil leaks. The first had to do with injectors - high pressure oil leak on the rail-fuel injection side of the HEUI system. CAT had issued an update not a recall which now uses a steel tube rather than a hydraulic hose part number is 24007717 TUBE KIT issued per engine serial number and cost about $800.00 to repair.
The second has to do with the cam bearings which is still being diagnosed. Estimated labor hours is ~ 30 and estimated cost to repair is $4000.00.
These are the only two engine related issues we have had and I do not consider these to be a major repair.
Would I purchase a 3126 with 40,000 miles on it. Yes, but I would have a authorized CAT Shop download the ECM history and do an inspection first. But then I would do that on any used unit that I was considering ( Cat or otherwise ).

I'm am close to pulling the trigger on the purchase of a beautiful 2003 Kountry Star with a CAT 3126 engine and 40,000 miles. I have tried to thoroughly research this before I spend my money. The more I read the more I think that this may not be a wise move. Are these engines prone to failure, and/or do they need more maintenance than other brands of diesel engines?
I thought that the greatest feature of a diesel (with proper maintenance, naturally) was many miles/years of service before major repairs are required. Now I'm not so sure??
