kinda yes n no.
1. The oily forged piston top is prob due to very slack oil ring tension (gonna fix that soon),
2. I accidentally plumbed the oil filter catch can backwards so the 1way valve bunged the crankcase up. sorted now
3. The massive oil leak captured on cam was actually caused by not sealing the timing chain side cover plate properly so the big gap allowed oil to pour out at high revs and further accelerated by the backwards fitted catchcan
2+3 is sorted and now I'm fixing issue #1 soon
