Ram 3500 4X4: I have a 2006 5.9HO 325 hp. I have lots of light

Customer Question

I have a 2006 5.9HO 325 hp. I have lots of light blue smoke from the exhaust when on a long down hill grade. I was having a blowby problem and losing oil through the crankcase breather system. This seems to have stopped and a manometer check showed that the pressure was well within spec. The engine runs smooth and quiet after changing out # ***** &6 injectors. There is 230,000 km or approx. 143,000 miles on the truck.

To me, this actually sounds like you may have an additonal injector beginning to fail or possibly one of the ones that had already failed and were replaced caused some piston and/or cylinder wall damage. This is somewhat common if an injector happened to fail by causing too much heat in a given cylinder. Engine damage can be caused in a VERY short time with a failed injector especially if you try to accelerate hard on an engine that exhibits loud fuel knock under heavy acceleration.. I had an engine fail in less than 30 seconds while road testing a truck that had a failed injector. I went around the block, turned the corner, accelerated hard and lost cylinder number 6 during the road test. Unfortunately, engine short block had to be replaced on that unit....
