Restarting A Long-Stored Opel (Reply to Letter); 1 page
Tom E. mentions it is helpful to remove the distributor and to run the oil pump gears, with a long flat-blade tool cut off from a screwdriver and run with a power drill, to pre-lube a long-stored engine. Other tips are to replace all rubber hoses in fuel and cooling systems, replace fluids such as engine, transmission and rear axle oil, add a new battery, pressure test the cooling system for leaks, and check the carburetor to see if it can be spray-cleaned for fuel residue or rebuilt.
