Jamie I know someone that can fix that!!!!!!








Like I said sorry to see that but come back bigger and better. Let me know if I can help.

Jamie with the rod out in one pic it looks like rotational heat at the pin and another pic, just impact heat from hammering things about.

With full floating wrist pins I cant see how any rotational heat could be possible.

Someone else stated a cracked cylinder and then a hydrolock, if there is no readable rotational heat transmitted into the top part of the rod, then , thats probably what happend.

From the new pics I cant tell, it looks like heat in one and not the other. You being there will be the best judge. No doubt at the rods main journal everythings fine.

That is a very unhappy mess.

Max, you lost a engine too, what was the cause of your mess? I hope that was a old, old pic.

Ok I tell what I think. I did a leak down and compression test a week ago. It was great. I never seen anything to make me think cy wall was cracked.I know all the signs of that. the last motor that cy went though 2 sleeves over that. with that said. that rod was in that cy. I think something was wrong with that rod when I put it in Had new bushing put in all the rods. would of thought if you could seen it. the machineist or I would of seen it. with that said .I never reuse a set of rods .. I think at this point the rod just broke. there is no signs of heat anywhere. you would of seen that in the bushing.Thats is what I think right or wrong.still need to take it all up to the machinist see what he thinks LOL

How many laps on those rods? A roundy round builder in my neck of the woods uses a brand name hi $$ rod in his DIRT Modified engines and he tells his customers they are good for 600 laps. A few of those customers thought that was silly. None of those engines made it to 700.

Jamie.. just looking at the first piston pic, do you
think the wrist pin can out and took out the cyl wall..
I've seen failures before but on yours the pin is
sticking out... doesnt look like the pin has any
damage but cant see the other side... sorry about
the breakage

200 runs on the rods. Mike I thought about the pin. But as odd as it is. The only part of the cy wall that is still there is where the pin would ride. not a mark on it..??

the clip/lock is still in the other side.

Were these rods ever magnafluxed or had another type of inspection? Do steel rods fatigue, and need to be replaced? I thought rods broke on the top of the exhaust stroke when there is no pressure pushing down on the piston, and it is pulling the rod apart at the start of the intake stroke. When does power start putting more stress on the rod than what I just described? What are the strength differences between I beam and H beam rods? Why would one want one over the other?

sorry guys, Im sticking to what i said ....

That cyl wall cracked and let the water in.

These blocks flex too much , thats it

You cracked the block she Hydroed and that's the evil coming out of that block..

Ask how I know.. look at this mess..

The Evil

Last bit of evil ..

I think the cam broke !!!!
