Constructed from premium heat-resistant gasket materials, the valve cover gasket is engineered to withstand continuous exposure to engine oil, high operating temperatures, pressure fluctuations and engine vibration. It plays a vital role in maintaining engine cleanliness, lubrication efficiency and long-term reliability.

What This Product Does:

Creates a leak-free seal between the valve cover and cylinder head.
Prevents engine oil leaks from the valvetrain area.
Helps maintain proper engine oil levels.
Protects internal engine components from dirt and contamination.
Supports efficient lubrication of valvetrain components.
Helps maintain engine cleanliness and reliability.
Contributes to long-term engine performance and protection.

Symptoms Of Wear Or Failure:

Visible engine oil leaks around the valve cover.
Oil residue on the cylinder head or engine components.
Burning oil smell from oil contacting hot engine surfaces.
Oil drips beneath the vehicle.
Low engine oil levels between services.
Smoke from the engine bay caused by oil leakage.
Dirt accumulation around leaking gasket areas.

Why Replacement Matters:

Valve cover gaskets are exposed to constant heat cycles, engine vibration and prolonged contact with engine oil. Over time, gasket materials can harden, shrink, crack or lose elasticity, reducing their ability to maintain an effective seal.
A failing valve cover gasket can allow engine oil to leak onto surrounding components, creating mess, unpleasant odours and potential damage to nearby electrical or ignition system parts. Continued oil loss may also contribute to reduced lubrication efficiency and increased engine wear if not addressed.
Replacing a worn valve cover gasket restores proper sealing, prevents oil leaks and helps maintain the integrity of the engine lubrication system. An OE Match replacement provides factory-style fitment, dependable sealing performance and long-term durability, ensuring reliable protection for your Porsche engine and valvetrain assembly.

Hylomar Anaerobic Gasket Compound - 300ml Cartridge

F/HG3400H/300M

Product Information

Hylomar Gasket 3400 is a modified anaerobic curing, flexible sealant designed to become a Formed in Place (FIP) Gasket when cured. The cured compound has good temperature resistance and high resistance to fretting. The cure is initiated when the compound is in contact with metal ions and in anaerobic conditions. The cure rate and final strength is dependent on the metals being joined and the temperature at which the component is used. The heat generated by a running engine will accelerate the cure.

Typical Applications
Hylomar Gasket 3400 can be used as a gasketing compound between machined surfaces. It is ideal for sealing between mating faces on engines and transmission components where resistance to temperature and vibration are essential.

INSTRUCTIONS FOR USE
Hylomar Gasket 3400 should be applied to clean and dry surfaces, free of contamination such as oil or grease. The compound may be dispensed by hand from cartridge, concertina pack, or via a screen printing system. Once applied the joint should be assembled as soon as practical. Any excess compound can be easily wiped off external surfaces with a clean cloth soaked in Acetone or other suitable solvents.
