I would suspect it is a bad wrist pin. What else could do that? Funny the new(reman block) that Cummins sent(not Dodge) is not the same(casting #'s and some other features) as mine. Pistons look bigger too... Think my old one was made on a Monday or a Friday..... Gonna break it in tomorrow..... going to the Mopar Nats & pulling a 26ft trailer bout 850 miles each way. .

How did that happen? and there sure is alot of rust in the cooling passages. Give us the details. I have a 2001 with 18k miles, almost the same as you!

The block design is different. if you look on the left front corner of block just above the oil pan rail you will see a Number. old style blocks have a 53 or lower number. new style blocks will have 54 or higher. they made the block thicker on the left side to prevent block from cracking. I have seen 2 with cracked blocks. 1 in a school bus and 1 in a motor home. Caused from Thermal cycle heat in the engine. .

May just be the picture, but the honing cross-hatch marks at the top of the picture looks like the rings never touched the wall - or at least never seated. Broken rings?



Hemi 71 GTX - let us know if you get anymore failure analysis.

Well the "new" block has the 54 the old block has:

"M9

B1360A1

4BG"

where the new block says "54"

Nothing even close to a 53, or lower is on the old block... .



As soon as I hear what it is I will let you guys know. .

Number six usually siezes first when the engine is run hot. The wrist pin would score the cylinder at 90 degrees from the scuffing visable to the right and was not a factor. Hmmmmm. Rust. Was it pressure cleaned, or did they leave out in the rain?

The engine was never run hot... The rust is from sitting out in the garage since last week in the humid, salt air... . #6 is not siezed... . None of that(rust) was there when it was pulled.....

Down right ugly!!! Hope it never happens to me or anyone else. Good luck with new engine.

I took a look at my block thought maybe dodge used a different block, but mine has a 53 casted in it .

 

[HEMI 71 GTX]

The old block was cast in Mexico the new block(#54) was cast in Brazil...
