Hello. I am on the road with my 645 CI with about 3000 revolutions, suddenly without noise or similar the power is gone and the engine control light goes on. Engine is still running, from the left exhaust come hot exhaust gases, from the right side only after petrol stinking cold air. Car is towed away, the workshop notes that there is no compression on the right side. Engine is removed: The pistons are ok. The bushings have no grooves. The cams shaft is ok. The cylinder head is ok. The steering chain is ok. The workshop says it might be the rings. But: the car had no oil loss, the car has never squirted. So how should the rings be worn out suddenly, without which the engine has ever squirted and there are no bars in the barrel sockets What could be the mistake? Thank you for tips or suggestions.
