Mercury's products contributed to its development in 107 years. The automaker was very popular on its debut. Mercury has manufactured and marketed plenty of quality cars and parts. The Mercury valve stem oil seal is one of its classic parts. The valve stem oil seal maintains the stem and valve guide lubricated to reduce friction. The valve stem oil seal regulates the amount of oil that is used to lubricate the engine by letting a certain amount of oil inside the valve stem.
Mercury has many great parts, but these parts can get worn after years of usage. Problems may arise after the Mercury valve stem oil seal has been used for a long time. The valve stem oil seal is responsible for controlling the amount of oil that is allowed to get into the valve guide for lubrication. Signs of a bad valve stem oil seal include smoke coming out of the exhaust, engine misfiring, higher oil consumption, and poor engine performance. We are here for you 24/7.
