Re: Good but bad weekend....
Sorry guys, didn't know that I got any replies, no message was sent.
Here's an update, the #5 cylinder is totally wasted, cracked from top to bottom, and it looks like it started to split, going around the diameter of the cylinder. The exhaust valve broke off and was laying inside the cylinder and the piston looks like a moon crater. This is just not going to buff out no matter how hard we try. All the exhaust valves were hitting the pistons, so it was a matter of time, but maybe the 150 shot just helped it come a bit earlier.
The new roller rockers, each exhaust valve retainer and by the roller tip were showing rubbing signs and it appears that they were not riding on the stem of the valve but on the retainer. Too many things happened to this motor to think what may have caused this. Some people are saying weak springs, some people say over-revved, some people say improper pushrod length, but we will never know, it's history and on the way to the junk yard.
I'm parting out what I can to get some block money and then we will see what happens with a new and bigger build.
