Head removal. One bolt away...I think
How do you remove this bolt? It is the bolt holding the power steering bracket on the driver side head. Do I need to take off the pulley too? There are two other bracket bolts I have already removed. Someone please tell me I am making this way more difficult than it is.
The damage is under this cylinder head. I already have the passenger side head off.

Well, I feel stupid. You are right, it is an open end 15mm wrench. Took me about 3 minutes to get it off. I was using a fatter wrench earlier that would not fit. Thanks!

IT's more likely that the extra rod clearance allowed the piston to stay at TDC longer and let the intake come down and hit it. How loose was that rod? Could the piston really turn that much?

The valve would have to move a ton for the kiss to look like that. I think that is probably from detonation and not the valve kissing. If the valve kissed you'd have a big eyebrow across the piston in the same spot and not just a hash mark all over the place. If the valve was bent to **** and not even seated in the valve seat then yes I would believe that.

Ah, that makes sense. I may have to wait till the shortblock comes out before I can find out what happened.
How much more work is it to pull the shortblock from where it sits right now?

The head gasket looks fine so there goes Bryans theory of a blown headgasket causing the cylinder to be water logged and causing a hydraulic failure. Its hard to say what happened especially that it happened during a normal starting crank up.

I got one here looks just like it. An Experianced eye could easily tell you that was not detonation It is the valve kissing it as the rod keep trying to push it up the cylinder before exiting the side of the block. I do not see any water damage at all so that is definately out.
Rod failure again. Man that sucks.

My engine bent a rod on startup also. I didn't have any evidence of anything happening. The only thing I can figure is an injector stuck open. No contact occurred in mine that could be seen. There does seem to be evidence of contact on this one but that could of happened after the hydro event and the piston was able to rotate or be pushed higher in the bore. I've heard of a few Ls motors that bent rods on startup lately. I wonder if it is an injector issue or if the rods stretch to a point where they bend or break.

Well, Just because its not connected to the crank, doesn't mean that its not pushing it up. That rod probly got wacked a couple hundred times as the engine was screaching to a hault. I'll guess that more than a few hits pushed it toward the top of the cylinder. Your first post didn't even note that the piston had rotated in the cylinder. You assumed that we were saying the valve had moved around?
So really you can keep your remotely correct assesment to yourself.
In my opinion, this is a classic example of rod failure due to rod failure.
