Constructed from premium heat-resistant gasket materials, the valve cover gaskets are engineered to withstand continuous exposure to engine oil, high temperatures, pressure fluctuations and vibration. They are essential for maintaining lubrication system integrity and ensuring the long-term reliability of the engine.
What This Product Does:
- Creates a secure oil-tight seal between the valve covers and cylinder heads.
- Prevents engine oil leaks from the valvetrain area.
- Protects the engine from contamination by dirt and debris.
- Maintains proper lubrication system integrity.
- Helps keep the engine bay clean and free from oil contamination.
- Supports reliable operation of the camshaft and valvetrain components.
- Contributes to long-term engine performance and durability.
Symptoms Of Wear Or Failure:
- Visible oil leaks around the valve cover perimeter.
- Oil residue on the engine or surrounding components.
- Burning oil smell from oil contacting hot exhaust components.
- Oil spots or drips beneath the vehicle.
- Low engine oil level due to ongoing leakage.
- Smoke from the engine bay in severe cases.
- Deteriorated, hardened or cracked gasket material.
- Oil contamination of ignition components or wiring.
- Increased engine bay dirt accumulation caused by oil seepage.
Why Replacement Matters:
- Valve cover gaskets are continuously exposed to extreme engine temperatures, oil vapours and thermal expansion cycles. Over time, the gasket material can harden, shrink, crack or lose elasticity, reducing its ability to maintain an effective seal.
- A leaking valve cover gasket can allow engine oil to escape, creating mess, unpleasant odours and potential damage to nearby components. Oil leaking onto hot exhaust parts may generate smoke and increase fire risk, while continued oil loss can contribute to reduced lubrication and accelerated engine wear.
- Replacing worn valve cover gaskets restores proper sealing, prevents oil leaks and helps maintain engine cleanliness and reliability. OE Match replacement gaskets provide factory-style fitment, excellent sealing performance and long-term durability, ensuring your Porsche engine remains properly protected and performs as intended.

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.
