LSX time???

lol, i dont want to cause drama. They offered to somewhat help but dont totally wanna stand behind their product. I trusted them and their design and got burned, oh well i guess, sucks but it will come back better.

you also paid for a quality product and they gave you a shitty one, all while keeping all the premium money you spent for a quality product...
 
any close up pics of the pistons once they were taken out?
plugs show any detonation? if it did detonate that very sharp thin edge right there were it broke would probably be the starting point.
 
these are the only other pics i have. Plugs didnt have any detonation on them or timing marks.

ya, i was told it would be fine. like i said if there was detonation, i believe it was from after the pistons broke and took in oil mixing with the fuel. but again, every piston was the same. so in my mind its a design failure. esp since my head gaskets were fine, plugs were fine other than oil.
 
The guy at racetek said detonation can also show up in the piston pins by slightly bending them making them much more difficult to remove than they were to install. The pins were hard to get out but i was using wire lock and was told it makes it harder to get the pins back out over using spiral locks, plus if the piston broke im sure that tweaked the piston/structure also making it harder to get the pins out.

Need to get a look at the top of the rod bearings also
 
As previously stated I would blast them all over the net, word travels fast on here you may get some results that way.

or tell them thats what you will do if they don't help you

yeah, even if you go with diamond, maybe theyll refund your money or give you another set of pistons you can at least sell

Regardless of lock ring, after you remove the lock ring the pin should practically fall out on its own. Detonation has a tendency to hammer the rod bushing and pin tower of the piston which would make the pin hard to remove. Detonation certainly isn't the only factor that can cause a pin to stick, but it is the most commonly seen.

Nice technique Matt...you ass hat.

dude, theyre screwing him over. I know this game is kinda at your own risk, but these things all broke simultaneously and there is definitely not enough meat on the top of that piston. it looks like any minute amount of detonation would blow right through that thing. thats a design flaw, which is not what jon paid for
 
I'm curious....

If the Piston design was "wrong",as suggested by this panel of experts....Why would the engine be assembled with "wrong" pistons in the first place???
 
My engine builder got the pistons and called the company back asking if these were safe to use, they ensured us they did all the tests/math yada yada and theyy would be fine
