I have a decision to make and would like your input. I bought a motor out of a 1992 USPS van
that was bubbling into the coolant. Got a decent deal on it. It is a 1992 6.2 with factory turbo. Serpentine belt set up and DB2-4911 pump and injectors. All of which I needed . I pulled the injectors, lines and pump out of it over the weekend. I have a 1990 V2500 6.2 na that has 200,000 miles on it and I think its time for injectors and a IP. Did a compression test and got about 400psi on all but one cylinder and got 385 on that one. I am probably going to get the injectors rebuilt but am unsure about the IP as its pretty expensive for that unit. My question is , can they test the pump for output and tell if it needs rebuilding or do they just go ahead and rebuild them? It looks pretty clean to be an original never been rebuilt pump. It didn't have the old style line clamps but did have the newer clip on type. Or would you take a chance and just install it and have the injectors rebuilt? I am also going to install my gear drive and hi output water pump at the same time. The guy I got it off of is a diesel mechanic and only wanted the truck for the body as he put in an isuzu drivetrain. He said that the motor started and ran fine except for the bubbling into the coolant. I am hoping that its just a head gasket as this will become my project engine. But I am going to have to drive my suburban for about another year or so before funds are available for a complete rebuild. I figure that I will have to turn down the pump about 1/4 turn from where it is now as a starting point for my na 6.2. Thanks for any input you can give me.
