I will be looking at a 6bt next week sometime but I wanted to know what components to look for on the motor itself. It is mated to a dodge auto tranny. Also it has over 300k on it, do they require a rebuild at that mileage? Thanks in advance for the help.

injection pump

to be honest it should have alot of life if it hasn't been turned up and abused. when i bought my donor cummins 6bt i bought the whole pickup and drove it home 200 miles. no smoke , starts right up all stock pick. 250k on it. now the getrag needs work but no leaks. for me i wanted somthing i could drive for a while and see how it ran gives me confidence in the motor. check water and oil and make sure they are not mixed. hard to do on a motor on the shop floor. look for leaks on injection pump and front and rear main seals. buying a motor on a pallet makes you have to trust the seller. many of the older 6bt pickups i have seen for under 3k. just my thoughts good luck .
