I seen pictures awhile back on here. I think it was somebody with a 12v and no gauges using some bigger injectors. It was either at DD or?? I can't remember the name, another company by/in? Nevada getting fixed. Anyways the pictures were posted... Man what a bad looking sight. Pretty sure I'd be teary eyed if that was my motor. I'll try to find them.

I don't remember the story behind this one, but here are a couple pix of a 24 valve.



Jack Nutter (aka Shooter now?) had a meltdown on his 24V towing a trailer up a grade. He was BOMBed but had a faulty EGT gauge that read too low. It started knocking and he damaged cyl #1 or #6 (not sure).

. . . and the head.



Take a look at the casting. . . it says "hecho en Brazil" That might have something to do with it

I've seen lots of busted pistons and cracked heads, but never had a personal expericance with that on a Cummins. Ford 7. 3's and GM 6. 5's are notorious for cracked psitons when they get too hot.



If I remember correctly, Jack Nutter had just a VA and maybe a set of injectors on the truck... I think he had the Mopar uprate ECM as well.



I have seen one 5. 9 piston that had the China Syndrome occur... It was NASTY to say the least. Dodge replaced the transmission, because they thought the "strange knock" was coming from a broken TC. Ended up needing a whole new longblock from Cummins.



***BTW, that is cyl #6 in those pics above.

I think that'd be the story Vaughn... and the pics that I was looking for... ouch

Funny, it was #6 that failed on mine. Sorry, I don't have any pics. Basicly the side skirts were scuffed and melted a tad.

Man if that was mine I'd bury the evidence and start over. Those kinds of pictures give me nightmares. Had a few big and small Mopars do that to me over the years and didn't enjoy one of them. Still have a 383 12. 5 piston around here I look at once in a while and my friends still can remember it. Yuck! That was almost 20 years ago!

Piston Meltdown

I work at UPS and we lost a perfectly good 12 valve mainly because the fuelers always shine on checking the fluids and the driver traveling on U. S. 101 at full governed speed in 5th(73mph+or-) ran it overheated until it lost power and seized. The thing had #6 melted and a few others on their way! The engine only had about 115,000 miles on it. $10,000 later, good as new. Spend a Dollar to save A Dime!!! Chris

Bad Memories

I'm not gonna be able to sleep tonight if you keep showing this awful stuff. I'll try and find that 383 piston and take a pic of it and the banana shaped rod it was married to. Talk about a match made in h@$$.

Wasn't it my6eatsv8's that said he does 1700 degrees regularly?

 

[MY6EATSV8'S]

well almost daily, I saw a little over 1850 today racing/passing a empty v10 dodge with 3 bikes in the back of mine today. .

I limit these exteam temps to under 15 seconds. My odometer says 153k as of today and is extreamly shy of truth. Otherwise I stay below 1300 but stay there for sometimes hours.

Melted #5, VA was the only bomb besides the low reading Autometer pyro.
