The quote was $1900 and change for all of the machine work on the short block, that might have included the sleeves themselves I’ll have to check. It does not include other parts like pistons, rings bearings etc.
Block is at the shop, getting all 8 sleeved just to be fully safe. The shop has done IDIs and have been around for a long long time. I plan to just do a full rebuild at this point.
This is the first time I’ve had it apart. The pistons have some scuff marks above the top rings but the skirts all look pretty darn good for a 250k motor. Bearings show wear but not what I would call abnormal. Nothing obviously wrong with any journals on the crank. I didn’t drive the truck...
ok, I got #5 cylinder out and there are deep scratches in the cylinder. I'll clean the piston and see if there is some visible damage, but it doesn't look good. I can catch a fingernail slightly on the scratches. Dang it.
I can't find my balancer puller, so I just ordered one along with a ridge reamer. Once they get here I'll pull the lower end apart, clean and measure. If the numbers check out I'll reassemble with fresh bearings and I'll do my best to get the insides cleaned out. Are there any common failure...
I dropped my heads off at a machine shop. I'm thinking maybe I just take the block in and get it done too? Full rebuild possibly. I dunno, wish the project was going back together and not coming apart still LOL.
Crank rod journals show heat discoloration and the pistons…how can they be that clean? Truck has around 250k on it, I don’t really know it’s history.
Thoughts? Factory or rebuilt at some point? Should the pistons have ford markings or IH markings on them I can identify?
By the way I got a CRC Smart Washer parts cleaner and it’s pretty nice so far. I also used a heated ultrasonic cleaner with OzzyJuice in it and I’m happy with the results. My motor was covered in oily sludge and the parts cleaner got the heads and intake nicely clean without much effort. The...
I just pulled the valves out of one head and one exhaust guide is crazy loose. I guess a machine shop is in my near future. The heads cannot be surfaced, correct? I also read to leave the freeze plugs in the head?
I got a radiator off of rockauto or summit racing can’t remember which. It’s aluminum one, but I have not personally had bad luck with aluminum in my vehicles.
I'll keep notes on my Ford "overhaul" thread in case anyone else has interest.
1993 Ford F-250, 7.3 IDI 4x4 w/5 speed. Truck was converted to a flatbed and put a dually rear end under it. Number of miles at present is around 250k.
I converted the front hubs to manual so that I could use low...
