Sleeving A 5.9 Block

Postby 93_Fummins » Fri Oct 02, 2009 11:18 am

Has anyone bored and sleeved a 5.9 block? Any hints or tips on sleeving one?

I ended up tearing up my No. 1 hole pretty good with the melted down piston. Apparently the pitson shrank as the perimeter melted away and slapped around in the bore for a good while. I haven't mic'd the gouges yet to see if it's in spec for an overbore or sleeve job, but judging from the looks of it, I'd say sleeves at the least...if not a new block.

I'm sure it would be cheaper to just find another motor and go from there, but I was just curious. It would have been cool if these motors were sleeved from the beginning like a big truck...

it doesnt cost much more to sleeve a cyl. then to bore it. you could prolly bore it .02 though unless its really that bad. if not i would ssay sleeve it and call it good. you'll be fine.

Over sizes come in .020 and .040 for these. If you sleeve it it has to be bored, sleeved, then bored to size. It's not really a big deal, pretty easy. Might be expensive though, with all the boring. If you wanna cheat, just bore the one over size and throw a .020 in it. If you're on a tight budget like me this is good enough for now! :lol:

Just enough power to break everything behind the crankshaft.

not to change the subject but i saw a crank from a big Cat 1692 block that melted a piston and ruined the crank because the piston and rod wobbled so much in the bore it wore the crank journal wore an 8th of an inch.... that motor went to runaway i heard it was not pretty

Good point, I didn't think about crank wear. I'll have to mic it when I finally get the motor out...

I now have a block.
Also have a head, but it's a non-I/C one.
Probably cheaper for both than the machine work on the block.
{edit}Hell, I have the whole long block priced for quick sale at $400.{end edit}

in what aspects are a non ic head inferior to an ic head?

Non-IC heads have 9mm hole for injector tip, IC heads have 7mm hole for injector tip. Aftermarket injectors are generally 7mm tips, I think. You have to get little bushings to run the aftermarket 7mm tips in the 9mm holes on the Non-IC heads. Some argue that the bigger injector holes lead to more prone head cracking, but I don't really know.

93Fummins- you summed it up quite well.

I think the heads from either one are just as good, with the exception of the injector bore to valve seat cracking. And even then, it wont happen if EGTs are kept in check. But, how many of these trucks have pyrometers? What, a couple thousand at the most, out of 80-100K produced?

so the ic heads can take higher egts with out cracking but both are pretty much equal performance wise?

All heads crack no matter the EGT's. It's just more likely to be a problem with the 9mm heads, but it's still rare for the cracking to develop into leakage.
