    Trailered home a 1989 F350 dump truck that looks great on the outside, but the 7.3 IDI is something else

    Good catch. Yep, its there. Got the new heads in today. They look nice I think: Precups have minor cracking, but nowhere near extending out to the fire ring: Did I mention they also come with a 1 year warranty? All in all I think a very fair deal and they got from Texas to Virginia...

    Picked up the cores. Other head: Crack is clear on the first head, but I don't really see it on the 2nd one, but I guess they did when magnafluxing it?

    I'm swinging by the local machine shop tomorrow to pick up one set of the cracked heads. I'll see if he can point out where they are cracked and I'll take some pictures. He also wants me to bring him the main caps and bolts so he can torque those to spec before boring the block. The rebuild...

    Called up CHI and they do have a set of rebuild heads in stock. They will accept a pair of the cracked ones as cores. $1,150 total, including shipping the cores back.

    I believe they magnafluxed the castings themselves, but let me verify with them. Good point! EDIT: Yeah, they magnafluxed the castings and that's when they found out.

    Machine shop called me back this morning and said that all 4 heads were cracked and no good to use. Any suggestions on where to pick up a good set of heads with cores? Found this place...

    Good point about bypassing one of the tanks. That said, I would like to take the truck back to stock as much as possible. Accurate Diesel gave me credit for 15 of the 16 injector cores I returned so that mostly covers the cost of FSV. I also decided to go with brand new injectors vs. rebuild...

    After noodling it over and speaking to the shop, I'm going to have them order the pistons and rings for me that are .020 over. Here's the full quite for parts and labor: So labor total of just over 6 hours or $660 and the cost of the .020 pistons is better than what I found online. This way...

    I took a closer look at both my oem STD pistons and the .020 Mahle ones and I don't know that I would want to be drilling into any of them. I then looked at the cost of a set of rings, cheapest I could find was $187 (ENGINETECH from rockauto), and knowing that I would need at least one more...

    Do you still have them?

    Great idea about just getting a gauge with the proper range. The Amazon reseller is giving me a hard time about getting a replacement. They want to see a video of me pumping and the gauge not moving. Already sent off all the injectors this morning are cores, so that's not going to happen for...

    I'll see if the machine shop would be willing to trade working on my '92 block in exchange for the '89 block. Doesn't hurt to ask and I can throw them both on the truck to take down there next week if he's will to at least look at it before deciding. While I haven't put the micrometer on the...

    Tore the original '89 block the rest of the way down. Here's the #8 piston that caused the damage to the cylinder wall: Not sure what would have caused the failing but afterwards, the wrist pin walked out and started scraping the bore: I have not found the clip yet that supposedly went on...

    As I was cleaning up and re-arranging engine parts to prepare to start tearing down the original '89 engine, I moved the heads and the pre-cups fell out of them. I was a bit surprised as I figured they would have been in there pretty snug. Not a big deal since I won't be using these pre-ups...

    I'll definitely do that when I receive the replacement. Its the Vevor brand I went with. Have some of their other stuff and it seems decent. I also looked at the Mophorn brand, but they appear to all be the same and in fact, looking at some of the comments on the Amazon reviews, the Mophorn...
