Description: Naraku Valve Seal for 139QMB 49/50cc+ engines, 4-stroke GY6 125/150cc+ engines, ZNEN engines, and 250cc 4-stroke water-cooled CN250 172mm engines. It can handle higher temperatures and have better wear resistance. OEM-quality valve stem oil seal made by Taiwanese and Japanese manufacturers. Naraku offers a set of 2 valve seals for 4-stroke cylinder heads. Excessive oil consumption may be down to the valve seals. Too much oil in the chamber can cause deposits to build up and could lead to the cylinder head failing. When removing the head, it is wise to change the seals.
