My 850 died the other day, lost power and seem to be firing on 1 cylinder.
Stripped the top end and found RHS Barrel and Piston badly damaged,. The piston has picked up on the front and rear face.
Barrel has gone for rebore, my problem is now what caused the seizure. If an oil starvation fault why only one side? I noticed the underneath of the damaged piston is blackened suggesting that the rings may have failed allowing blowback. Another suggestion is a bent rod, although before the problem the engine was fine - no unusual noise or vibration.
Do I need to undertake a complete rebuild or just do the rebore with new pistons.
Any suggestions appreciated
