Fun story. LOL.

I"m glad to hear it had a happy ending. I'm hoping for the same. I just don't want to tear the motor completely apart if I don't have to. I also don't want to go through a bunch of effort and then have a bearing fail and have to tear it all down again.

I just want to get back in the saddle again. It's been over a year since the initial downtime. :(

Haha!

So, seriously, do I worry about the aluminum shavings? I am considering splitting the case.

I am serious, where did it fail?
I don't see the failure point, the gasket is intact.
Forget the rest of the engine, get the head tested first.

Check the cylinder bore by lowereing the piston, take a couple of pics.
Relax as in one thing at a time.

All the shiny areas are where there is no gasket material. There was coolant in the cylinder and you can even see it on the valves and surrounding area.

Also, I looked at the cylinder and found one vertical stripe. Is this cause for concern?

No concern to me, the bore looks good with the exception of the single scratch.
Aren' the missing parts of the gasket surface stuck to the cylinder gasket area?

Here's a blown gasket caused by a broken compression ring.









Well no matter what you need to pressure test the hed to eliminate that IMHO.

No gasket material on the cylinder head. :(

Also, the cylinder head bolts were quite loose.

Well, without stating the obvious, but if the cylinder head bolts were "quite" loose, wouldn't the coolant be able to flow past the gasket (regardless of whether it was stuffed or not, especially under pressure) into the bottom end?

So your choice is to get the head tested (to make sure it is not the problem) then buy a new gasket and torque wrench and fit everything back together. Or skip the head test and hope for the best.

Bad,
There's this...

http://en.wikipedia.org/wiki/Deductive_reasoning

Are the copper washers on the head bolts in good shape?
