IDI head removal question

[IDIBRONCO]

Thewespaul, it could already be at .030 over. It's been rebuilt already.

Just saw that... he might get away with sleeves but I'd find a different block

On a 6.9? I thought there's plenty of cylinder wall space.

 

[Thewespaul]

Ah 6.9! Missed that. Yeah you're good, you might even bore it out to a 7.3 to save money on pistons

Right on! Man that's good news you had me worried for a minute there.. I can still use the 6.9 heads with 7.3 pistons?

 

[idiTravelAll]

..that was probably a dumb question I realized as soon as I hot submit..

 

[Thewespaul]

No dumb questions here. There are some differences with the 6.9 head but you should be fine

I would take some synthetic steel wool to it and see if there's any pitting before condemning it.

I went out and bought some marvel mystery oil tonight so I'll dump that in there for a couple days first. I did read up boring to 7.3 not the best idea so I'll check some machine shops and hopefully (fingers crossed) be able to get by with 2 new sleeves, hone, rings, bearings, and all gaskets. Thinking about selling the turbo kit to help fund that craptastrophe.

I don't know how the market is where you are but I can get a block here for cheaper than that machine work

I'll keep that in mind, they're difficult to find here, only found 1 at a junkyard.. 116k on it and they want 1600 for it if I remember correctly.

As I'm looking at the pics I see several things that tells me this is a 7.3 engine.Not a 6.9. I see block plugs that normally are open in a 6.9 and those pistons are 7.3 by the flame trench in them. The 6.9 has a rectangle type flame trench. Please take pics of the block serial numbers that are stamped into the drivers side front top of the block.They are next to the injection pump gear tower housing.

Will do, man I hope you're wrong though. The heads are stamped 87 but I'll check it out in a few here.
