LB7: Interesting Melted Piston...

[MMLMM]

Found this interesting. Notice how it melted, but left a perfect part "under" in tact??

Steel takes a little more temp before it can be used as fuel......:thumb:

Lol, I know that.....I just found it interesting how it melted like this.

I have seen my share of cracked pistons, but this is the first real melt down (with no crack/hole) I have seen.

I have seen another one close but not that bad , it was in a motor that had a head gasket problem and had been severly over heated. imagine the heat it takes to do that :baby:

Wow that's melted nicely


I once melted the edges off of all my pistons on my turbo'd 4runner...but it wasn't that severe at all..just little chunks and pieces around the edges of all pistons :rofl:

Nice

good way to lower the compression a little right?

We have lots of melted pistons... We have never holed or cracked one though.

How did the block deck look between cylinders?

lol kinda reminds me of blowing a weld off a piece of steel with a torch where the weld leaves and steel is unhurt

Wow there's a walk down nightmare lane...... I have a piece of McRat original mechanical art work on my desk.

Holy Crap!

Nothing that I could see out of the ordinary, no ridges burnt through it etc. That piston was from a motor I bought a year ago that "lost an injector"

Wow!! Just 8 passes on that built motor???! What happened?

8 passes on a built motor God that would make any checkbook CRY!!!

Most of the time you have those kind of issues you also have a spray pattern that is out of the bowl. That also causes excessive heat which in turn does melt pistons. i seen several dodges that looked that way.
