That's the combustion chamber for cylinder #6 moments after I pulled the head off today. It's really hammered badly. Head is not salvageable without extensive welding to build up damaged area and then resurfacing. Ouch.

In this picture which is admittedly kind of dark you can see the melted piston and exposed upper compression ring. What you can't see is the 3 inch long crack in the cylinder wall about a half inch below the deck of the block. Nothing good here.
Remarkably cylinders 1-5 are in exceptionally good to excellent shape with none of the signs of detonation that #6 has. This has me somewhat puzzled. I originally thought I was just having a hard time tuning it out but I really have my FMU cranked up right now. I am beginning to think I may have been having a fuel delivery problem on # 6 for a little while now. I'll have to figure out if the injector for # 6 was firing consistently. Could be a problem with the wiring harness.
Oh well. Lessons learned the hard way. I'll get more/better pictures when it's not freezing outside. I was a little chilled by the time I got the head off.
I am now looking for a good M30B35. I want one from an e24. If any of ya'll know where one is pm me.
