Hi, My name is Marecki and I come from Poland. I own a 1986 military M1009 with a 6.2 liter diesel engine. I have a liltle problem with the engine. It produced a loud "chain like" noise, so I disassembled it. Is the injection pump shaft suppose to be able to rattle around while the chain cover is off? Or are the bearings in the pump simply too worn out. I have a couple of questions too. 1. Are the parts in my Blazer the same as in a K5? (both the same year) (I'm interested especialy in brakes, steering, and axles). 2. Is my engine (6.2 litre diesel) the same as in non-military versions? (exept ignition running on 24V power suply) 3. What do You think about parts from LMC Truck? 4. Is it nessesary to lenghten the drive shafts, and brake lines for a 4" lift, or will the original ones be ok?
