Ouch! Not good vinny!

Look at the bright side...your chassis is freshly lubed. :D (ducking.....)

Don't ya just hate it when that happens??

I figured a couple tubes of JB Weld I'll be good as new.

That just helps to keep the rust off the underside. I would use an expandable rubber plug in the hole and some heavier oil

I referred to my Land Rover as "self galvanizing".

I bet the CIA, FBI, & IRS conspired to steal it! They needed it to keep hiding that missing airplane!

Next time your jeep starts telling you a knock-knock joke, I bet you will ask "who's there?" faster!

4, 6, 8? Old or new?

I had an Audi that ran fine with only 5 cylinders. I'm sure the jeep will too.

That looks like the bottom of a 4.0. I am guessing 99 or newer. Remember when the 4.0 was considered invincible? I wonder if piston cracked first. I have seen a bunch of them come apart only to find the piston skirt laying in the pan, or jammed into a counterwieght.
I think up to these years, they were great motors.

The Aussies are listening for it pinging.

It's a '99 4.0 Around 600 miles since a rebuild. Gave me about a 4 second warning before it let go. Had been running absolutely perfect before that.

This is why I rebuilt it in the first place.

I've done 3 or 4 that looked exactly like that one. Whole side of the piston missing. The earlier ones ( 99, 2000)and seem to be the habitual offenders. I think I crank kit is fairly cheap, but I find that they suck to r&r .
It is nearly impossible to find a used motor for one of these, they all blow up.

Piston skirts and heads cracking between # 3 and 4 are the most common issues with these motors. When I did the rebuild I went with Speed Pro pistons. HUGE difference in piston design and skirt construction. I'm really pissed, because this is the first time I've had a rebuild let go on me. ( other than a race motor..) and like I said, I had absolutely no warning.

No warning, catastrophic - I'm sayin' rod bolt failure.

Vinny, remember those extra bolts you had after you rebuilt it? Yeah they go there. (all meant in fun)

Wow! That's some damage. I guess better than through the block. Of course I'm thinking the block isn't unscathed.

SBC swap!

Is that a Jeep 991 GT3?

That was it's way of saying that it didn't want to be rebuilt, Vinny.

yep... SmileWavy

Shouldn't the question now be "3, 5, 7?" ???
Bummer about the motor.

Yeah that's the first thing I thought also. Block is trashed. Cracked along the oil pan rail.

I remember one time, after rebuilding a manual transmission, putting it back in the car, then going over to my bench to put tools away and clean up. Looking up in horror and seeing a synchro ring hanging on the pegboard. I was slightly upset.

Vinny, I did that once with a DB4 engine, getting ready to try starting it and kicked an oil chain tensioner piston across the garage floor. Eff Me! At least I hadn't tried to start it yet.

I do have a 600hp BBC, sitting in the garage , that I might be able to shoehorn in.:)
