wondered the same thing. that doesnt look like a engine with so few miles

 

Detonation is caused by having the timing too advanced, or too high compression. Either case causes the ignition of the fuel too early;making the highest pressure in the cylinder before the piston reaches TDC. However; in both cases the piston is near TDC when it happens. This causes great pressure on the piston, the head gasket, the connecting rod, and the rod and crank bearings. This does not cause any increased pressure near the bottom of the cylinder.

So, as my opinion as an engineer detonation didn't cause this.

 

Hmmmmmm....I'm feeling a little better now.

 

I'm 99% positive after seeing those pics, look at the ring. you can see a crack in the ring just below that red brownish deposit, like the ring jammed and cracked lengthwide..almost like it's split in half. If you would take the piston out you would probably see scuff marks from the ring seizing, this is starting to look more and more like a severe ring gap issue. They should build you a new engine free of charge. The chamber damage is from loose piston chunks.Severe detonation leaves tell tale marks, looks like a pitted surface and all pistons would show it, not just one (even though it can lead to only 1 piston failing...) this is not the case here.

The walls looks glazed up..certainly no recent honing done there...or it's an engine that has accumulated some miles...can you check the bore size? measure if this thing has had an overbore at all..maybe they just got a std. size block (or an already oversize one but if it's std. you K NOW there was no boring done there) and dumped in some new pistons, w/ the bore beig worn most on the top and setting the ring gap there that would lead to this kind of problems...

Looking at the pics again, almost looks like I see a carbon ridge near the top and a wear ridge...feel it with your finger, for all you know this might juts be a core that was not bored and certainly not honed.

 

I took apart my engine with 5K hard miles and you can see the cross hatch on the walls. This looks like crap. I would say you definitly have a case against them here. This is poor workmanship!

 

Once old Clarence and his boss see these pictures they are going to go into damage control or complete denial.....you have one Mechanical Engineers professional opininon.....i think all you need to do is get this on a professional letter from a "PE" and the credit card company will rule in your favor....remember they are the jury you making your ulitmate case to and if it costs $200 for a local ME to certify this it may be money well spent, in any event see what they say first and then talk with the credit card company and see what they need in way of documentation.... we are kicking *** now.....

 

I completely agree with Turbo. Also a piece of piston could have wedged in and cracked the block.
What is that red on the ring?
I would definately have a mechanic look at it NOW in this condition.....just a look couldn't cost you much and you WILL need his opinion later.
What do the other cyls. look like. Any cross hatch?

 

Post some close-ups of other cylinders.

 

lets not forget "material misrepresentation"..... if the block was never honed....and it has a ridge.....and they sold it to you saying it had been, and the photos and the "PE" says other wise it just adds more wood to your fire .....

 

More pics....same cylinder. I'll get the others shortly. This is about as close as I can get, and it starts to blur at this point.

 

Ole Clarence just emailed me....didn't have much to say.....

"Hi Brian, I received your emails. I will add the pics to the claim info.

Thanks
cb"

Looks almost like a used block with no machine work done to it at all, couldn't get much worse than that.

 

that dosent look good at all

 

sure it could, it may only have 2 bolt mains with original hardware

 

Back-up and use zoom.

 

when I had my 434 built( and Dynoed I saw it ) I asked what the break in procedure was.
He said 1/4 mile at WOT.

If it's really been dynoed, it's already broken in.

And looking at those pics I wonder if the piston could have hit the cylinder ridge and broke...Bad Bad Bad

 

Incredible.

 

Well those cracks would definitely explain the milkshake, too.
