So you are running the cylinder without air going in or out? That would be like adding a shock absorber to the crank. And you will lose more than 25% of your power because the other 3 cylinders will be pushing this unused cylinder around. You'd be better off removing the piston completely rather than leaving it as is. And the oil burning issue will not go away. There is something leaking oil, and it was going into a cylinder and being burned off. If it is leaking into the burnt cylinder, that could be a major problem...

Have you ever heard an old Harley engine and seen it shake? They are designed as a 3 cylinder engine with one cylinder removed. There is indeed a reason old Harleys leave oil everywhere.
