Today I finally got around to getting my 93 K2500HD back in the shop. It has been sitting for well over a year[maybe 2?] since I worked on it last. I had bought this truck as non-running that was making very bad knocking sound . The PO had started taking it apart and then threw in the towel and let it sit for a year or 2.
Shortly after I bought it , I got it running with the crossover exhaust pipe removed. It did have a very terrible knock that I could easily hear over the very loud exhaust. It did still have good oil pressure, so there was still some hope but I was going to pull the engine out to really check it out.
It turned out the bad knock was mostly the broken flexplate.:idea: As long as the engine was out and on a stand, I figured there was no better time to put in new head gaskets, ARP studs, timing chain and reseal the whole engine.
After pulling the heads off I found divits in the pistons from running with very bad injectors and rust in 1 cylinder from either a leaky head gasket or from sitting with no exhaust and a valve open. I pulled that rod and piston out, honed the cylinder and put new rings only on that piston.
I put it back together with Fel-Pro head gaskets, ARP head studs, Cloyes timing set, new valve seals, 97 HO water pump and a new set of "Medallion" injectors from Accurate Diesel. I cleaned it all up good and painted it Alpine Green which is better known as Detroit Diesel Green.
I cleaned up the engine compartment and painted it also. I put in Energy Suspension Poly engine and transfer case mounts and bought a oil cooler line set from Lubrication Specialist.
I put the engine in and got it running but it ran terrible. It wouldn't rev and there was lots of blue smoke. Apparently the injection pump went bad from sitting so long. :banghead::banghead: I didn't have a spare IP at the time and other things came up so the truck got pushed outside and ignored.
Now with the frame on my 92 getting close to dangerous, I need another truck running ,so this 93 got the call today. I'll be swapping a used 4911 IP on it, making some new battery cables for it and more than likely doing rear brakes and new steel lines since the rear reservoir was empty when i looked in it today.
Today was just getting it in the shop and start cleaning and looking over what else will need to be done to get it drivable.
I will do a separate thread on building battery cables. I've bought the tools and supplies to make my own since I have so many trucks and other equipment .
