My pistons sure have alot of play in the cylinders

Finally pulled the heads off the 454 that was in my Orange Blazer from February through July.

There was alot of hardened nearly crystalized oil deposits on the pistons, and I can take nearly all the pistons and move them from side to side in the cylinder bore.

#3 Cylinder wall has a few spots where it looks like small sections are pitted... like little low spots where looks like the metal is bad.

Any guesses as to the demise of this motor?

Mud got into the motor and ate the crap out of the cylinders.

Sounds like it's time too bore it and install some new pistons.

Oh, and I forgot to mention the several cam lobes going flat, and huge divets in the bottom of the lifters.

And yes, some mud/water mix splashed up a few times and soaked/drenched the open air filter. I put a closed one on a while back.

I'll also admit to running this motor hard. I don't intend on using this block for now. I'll set it aside, and someday take it .060 over.
