Well, I probably screwed up. Been working on my 1984 F350, with the 6.9 IDI. Last week took the tranny out and to a shop for rebuild. Case was junk, the rear bearing had spun. So, put it in this weekend. Got a lead on an engine out of a F350, with about 77,000 miles on it. So, traveled about 30 miles, looked at the engine, and it was one of the early models. Didn't really want it, but, paid $250, and the farmer loaded it for me. I figure, even if it isn't the later model block which is better for a rebuild, I can still get enough parts from this one for that much money to make it even.
Been concerned that my heads were leaking. My thought process is, to take the new engine, give it a down-and-dirty rebuild, and store it away in case the one in the truck decides to slag itself down.
Thoughts? Comments?
i think you got one heck of a deal even if its the early model block.the only real bad part about the early blocks was the block heater.if you dont use it its no big deal at all.you if you like using the block heater you can get a heater that goes inline with your lower radiator hose instead,by doing that you wont worry about a "block" heater cracking the block because it just heats the coolant.hope this advice makes you feel more at ease
Already thought of that. Looking for a Kat's heater for the engine in the truck. When I rebuild or tear into the new engine, am seriously considering taking out the block heater and installing a freeze plug. I want to put this new one on a stand, check out the main bearings and rod bearings, then, if they are OK, replacing the head gaskets and putting a set of head studs in. The farmer I bought it from said that he thought the fuel pump had gone out. I just want to 'tinker' with it to solve any issues before it goes into storage/standby status.
Orange citrus cleaner from Walmart, and a couple bucks at the car wash. It wasn't bad at all to begin with, but, as usual, dirt and dust had stuck to anything with oil residue. It started out very clean, so, I am assuming the old gentleman who owned it had cared for it.
The challange is now to find a engine stand capable to hold it while I work on it.
The old gentleman didn't want it because he knew nothing about diesels. He had inherited the truck from his father-in-law, and when he was driving it, it seemed to lose power. He just decided to swap a gas engine in. The man who helped him swap engines works for the local Mack dealer, and thought it had lost the fuel pump, but the old gentleman still wanted it swapped.
I haven't tore into it yet, but, I admit that I am a touch concerned. It almost sounds like it has some slop in one of the connecting rods when you nudge the flywheel back and forth. I still figure it's a deal, just because of all the spare parts I would have if it isn't a prime rebuilder.
