In 4 stroke engines, how to replace valve seal? a. Find TDC, depressurized the chamber, collapse the valve springs, remove retainers, remove old seal b. Engine at TDC, rotate crank shaft to TDC, remove the cylinder head, compress valve spring, remove retainers, remove old seal c. Engine at BDC, remove the cylinder head, rotate crank shaft to TDC, compress valve spring, remove retainers, remove old seal d. Start with BDC, remove the cylinder head, rotate crank shaft to TDC, compress valve spring, remove retainers, remove old seal
