Perhaps you can (eventually) push the pistons way down and then get into each cylinder with a deglazing hone and hone away enough of the rust so that the piston can come out the top.. you're probably looking at re-boring anyway ??
In fact, if you're re-boring anyway you're into it for new pistons... whack !!

Yep unfortunately I'm afraid it's beyond a simple re-ring.

I have heard that brake fluid can be helpful to free up frozen pistons. Might as well try every thing at your disposal to free them up before taking them apart with a chisel. Cheers Dan

Well I made a little progress tonight. But I'm not liking what I found.
Here's what the worst cyl looked like sunday before I started to soak it.
Look mom, no pistons!
Shots of the bores. They're not as bad as I thought. They'll need to be bored though I think.
Now for the bad part...
Number 3 piston has been melted away at the crown.
So tomorrow I'll be taking the block to the machine shop to see what they can do.
Oh and here's what It'll end up in.

What do you think caused the piston damage? IP or injector?
Also I'm wondering about what I should do at this point. I know another TD will set me back $700 or so. Plus $300 for a re-ring/bearing kit.
Should I just try to grab the turbo setup off ebay I'm bidding on. Rebuild this engine. And add a few things?
I'm thinking about a turbo setup, intercooler, having the IP tuned, and a small propane setup for WOT. (the propane would be later down the road)
I know the TD's had the oil squirters. This one doesn't. So I was thinking about using a larger radiator, the intercooler, and adding a oil cooler as well.
Does anyone make a larger cap. oil pan? Clearance isn't an issue for my setup.

That looks like severe overheating to me. The aluminium is melted at the top of the ring lands meaning the heat had to come from the combustion chamber with no cooling available to take it away. I would get the block magnafluxed before boring to make sure there are no serious cracks which would turn the block to junk. And clean the snot out of it to do a thorough visual inspection. It may be possible to redistrip the block to get rid of the rust and crud. This could save you the heartache of spending money on a damaged block. Cheers Dan

Took the block to the machine shop. He said it'll need .040 So now I've got to find an engine kit. The local parts stores don't have anything.

Well I had a chance to speak briefly with Jack. I've got a few more questions.
1. Should I replace the oil pump? I know his kit comes with one. But the other kits I've found do not? The car had 140K on it.
2. Cam and IP lock. They look simple. I could use an angle iron for the cam. The IP lock looks like nothing more than a pin I could turn on the lathe.

The cheapy timing tools on the market are pretty much as you have described. I Just got a set off the net for about $ 79 from emiata.com. Though the pin and plate you can make yourself the dial indicator and adaptor are worth the money as they are difficult to produce with any degree of accuracy. And you can't do the timing with out them, just the pin and plate are not enough. Cheers Dan

I've got a dial indicator already and I'm certain I can lock it in place with my mount.

The factory spec for wear limit on these pumps is in the Bentley...I recall it being 6 thou or something (you use a feeler gauge to measure the backlash)... lemme know if you don't have one and I'll look it up for you. There's also a spec for wear on the ends of the gears... again using a feeler gauge and a straightedge.
Myself I use any excuse possible to upgrade to the 36mm pump.

If you wouldn't mind, the specs would be great to measure it.

Don't bother with it now. I've just ordered my kit with a new oil pump as well.
Now to wait a week or longer. :cry:

I haven't updated this thread in a while. So here goes.
Got my block back from the machine shop. Got it all cleaned up, and bored 1mm over. She's pushing 1630cc's or 99ci now
The big D!
I spent the day putting the short block back together. Might work on it a little more tomorrow if I get a chance.
I coated the block in yellow. Mainly because I've got an idea for "conversation" reasons. I imagine when people here me pull up in a samurai that's "knocking". They'll ask. I plan on getting one of the "CAT" tags a lot of construction trucks have. That way I'll have an "explanation" of what engine it has.
I've already got my adapter kit for the engine. Already got a new clutch on the way. And I've got a rebuild kit for a turbo. Hopefully my turbo setup will be here shortly. I've also got a oil cooler and dual remote oil filter setup coming in as well. I'm looking around right now for an intercooler setup. Lots more to go. But at least I'm making progress.
