this project just got put off till summer. got the cylinder head back on and the piston is still hitting the top randomly. pulled the cylinder head off and watched it. every 3 or 4 cranks the piston comes up too high. I'm guessing there's something wrong with the crank bearings or connecting rod which is going to be a long summer time project. I bought this as a 'doesnt run, dont know why' mystery case and its been fun. my first post morten looked like he ran it out of oil and a valve seized hitting the piston but apparently it did damage to the lower end too. I bought a box of used bolts, etc off ebay to get it back together and it included a piston wrist pin so I tried it too so its def in the low end.
