What comes inside the HIHIAV VS50825R repair kit?

The kit contains all the primary sealing components needed when replacing a valve cover gasket assembly, reducing trips to the parts store. Parts are supplied in one boxed package to ensure nothing is lost and to protect soft rubber components during shipping.

How do I install and what should I watch for during replacement?

Installation follows standard valve cover removal and reassembly steps; careful cleaning and proper torque values are important for a reliable seal. Replace the spark plug tube seals and grommets whenever the valve cover gasket is changed to prevent future leaks.

• Clean mating surfaces of old gasket residue and oil before installing new parts.
• Lubricate new rubber seals with a little clean engine oil to ease seating and prevent tearing.
• Tighten bolts in the recommended sequence and to the manufacturer’s torque specs to avoid warping the cover.
