Happy New Year all,

Just pulled my old engine apart, I think I found the problem with it:


Broken crankshaft, bent #1 rod. I'm kind of suprised it didn't blow up, it stayed intact, well contained in the caps anyways. Lots of big chunks of crank debris in the pan. I think I'll go easier on the new engine
