You'd have to have a big hole in your piston for anything to get past it into the pan.

Hope this works out in your favor

I see you found cracks in the bore. Hot combustion chamber and cool water The quenching of the aluminum piston top could easily fracture that piece off.


I'll be watching this thread closely as I'll be needing another motor for my '77 in the near future.

That is some really bad QC. If you did everything right they should warrany it for full replacement, and labor. Is the heat tab melted? engine builders will put a heat sensitive tab on an engine that will melt if the engine overheats. The builder may ask for a picture of it to prove its condition. If it is melted you will most likely not get anything from them.

Good Luck!!!

This may be obvious but make sure your 3rd party inspector is aware of the KB ring gap issue.

That'd have to be some pretty serious detonation. The weakest part (or the most flexible) would be the piston and valves, which I think, are the ones that take most of the beating. The rest is immobable, and surrounded by coolant (although that wasn't exactly the case here). Wiser heads may say different, but my gut thinks that the block suffered damage previously.

My money says we will never know the real reason for the failure, and that a proper and just compromise will be reached.

The broken piston and cracked cylinder may be symptoms not the cause. Fluids do not compress and if enough coolant got in that cylinder on the compression stroke things will break. Especially if the engine is cranking up a bit. Turn the engine over to TDC on that cylimnder and see if the piston comes all the way up. If the rod is bent it may be one more clue coolant in the cylinder was the cause of the damage.

I expect the rod to be bent. Detonation can cause this too but I suspect the cylinder was cracked first and it tried to compress coolant bending only one rod. Probably caused by a blown head gasket.
If I owned Blueprint I would exchange you a new motor no charge and pay all shipping. This is probably rare and I can't think of a better way to get some good publicity. My money is on them replacing it. But if they don't. put her on E-Bay

Piston does come all the way to the top. No noticeable valve damage, no noticeable valve rod damage, not noticeable damage anywhere other than the piston top, and bore.

Good thing is, I have a very sharp operation that is going to check everything on this, but I have another concern about my written approval for third party inspection, and it has to do with the wording. The part that is in bold basically says I can't alter the engine, meaning only a visible inspection is allowed. WTF? I didn't catch that the first time. Do y'all read that this way? Sneaky biatch's....If I pull anything else off the motor, then I have altered it. That may not be what they mean, but you can surely read it that way.

Disassembly does not constitute repairs or alterations. Unless your 3rd party guy messes with the ring gap or cuts something out of the way to remove a broken part. Just be sure to specify to the 3rd party mechanic, ratchets and sockets only.

Not the way I read it. But you must put it back together for them, which tells me you can take it apart for inspection.

To me that means substituting any components or repairing any "damage that could be attributed to you" ....I think a disassembly and inspection by a competent and reputable engine builder would not fall under this description...

Please tell us you paid by credit card???I am ASE certified in engine repair and no way, no how did you cause this! All this talk about detonation is poop too!If your timing was so advanced to cause this, the engine would have cranked so slow you would have noticed it!! Please call your credit card company and tell them that this company sent you a defective engine and would like them to credit you back.Most times they will credit you back and put the burden back on the merchant.
