I can't believe you would consider repairing a piston.....just me.

Re: Would Anybody Attempt To Fix This?
 

Replace it !
And you want to tear it down and get the leftovers out of the engine.

Re: Would Anybody Attempt To Fix This?
 

Be good to know the brand so we can all avoid it!

Burt Munro would melt it down and recast it, I'd toss it and thats why I don't hold any world records. What went through the top? Ditto on removing the rest of it.

My Father welded up one for his E type jag in the 70,s it got mashed by a valve and he was short of $$ so welded it up, My brother still has the car,piston still in.
But Not for me,I would get a new one or set.

Only way to repair it safely is to drop pan, pull scrap aluminum out of the hidden places, and replace the piston, same as flatheadmurre suggests.

Re: Would Anybody Attempt To Fix This?
 

Two companies that come to mind are Egge and Arias that will make any piston to your specs. I would be more concerned with the fragments that are in your oil system. Ever try to TIG weld an aluminum part that has been saturated with oil? I don't care how you degrease it as soon as you hit it with any heat you will see the oil bubble to the surface. I know you will get several people that "do it all the time" but I would get another piston.

Re: Would Anybody Attempt To Fix This?
 

If you weld it up and it doesn't hold you will have to tear it apart again. The next time may cause a lot more damage. Not a good idea in my book.

Tear down to clean out and replace the piston.

Re: Would Anybody Attempt To Fix This?
 

You are looking at a COMPLETE teardown.
All of the material that came off the piston is now distributed evenly ALL through the engine. Every nook and cranny and oil passage. A lot of it is hammered into the babbit. Lightly scrubbing the babbit surfaces with scotchbrite MAY remove it. May not.
In any event you need to look at everything in the engine for debris. After all this and reassembly, the engine may last forever but on the other hand it may not due to left over aluminum debris you missed.

If you can replace the piston, do it. On the other hand, when I dropped an exhaust valve in the early hemi in my vintage dirt car, it did the same type of damage to one of my JE forged pistons, which were new less than two years before. When I contacted JE, they wanted to sell me another set of 8 pistons for another $1200. My builder magna-fluxed the piston and found no internal damage. He then had it heli-arced and re-magna-fluxed, and found no problems. I've run it in at least 30 heats since then successfully.

Bottom line : replace it if you can, but they sometimes can be fixed if the circumstances require it.

EDIT : I should add that even though the piston was repaired, the engine was torn down completely and thoroughly cleaned.

Re: Would Anybody Attempt To Fix This?
 

I would contact Egge for a new one. I would also be finding the cause and address that

Re: Would Anybody Attempt To Fix This?
 

Hi Everyone, Wow that sounds like a sad story.

Just an idea Tony, and you didn't say exactly what the brand is, but if you know, and tell us what the piston is, someone may be able to help.

As we've seen recently, a few people who hang around here, have a thing for saving old ford parts of every description.

As others said, I'd be scared to run that for long without a very serious cleaning.

Do you know what caused this?

Re: Would Anybody Attempt To Fix This?
 

By the time you try to fix the damaged piston you could replace it with a new one. My suggestion is do it right , otherwise this will come back and bite you in the $$$$$

Yep... could not have offered better advice than this.

Re: Would Anybody Attempt To Fix This?
 

You do not say what it is out of. Pistons are made by dimension, not by brand of car. It will be a certain stroke, bore and number of rings and of course weight. Lots of different make cars had the same bore and stroke.

Listen to Pete!

Re: Would Anybody Attempt To Fix This?
 

Do it right...sleep good at night...

Re: Would Anybody Attempt To Fix This?
 

We use Egge or Mahle. They will make pistons to spec. Not cheap, but what of real quality is?
