Product Information

Engine Valve Cover Gasket.
The OE Match Engine Valve Cover Gasket is a premium-quality replacement engine sealing component designed to provide a reliable, leak-free seal between the valve cover and cylinder head on compatible Porsche engines. Manufactured to OE specifications for fit, material quality and durability, this gasket prevents engine oil from escaping while protecting the valve train from dirt, moisture and other contaminants.

Fits:

Porsche 957 Cayenne 3.6L 2007-10
Porsche 958 Cayenne V6 3.6L Petrol (300Hp) 2010-17

Diagram Ref No 1

Manufactured from high-quality heat-resistant elastomer and premium sealing materials, the gasket is engineered to withstand extreme engine temperatures, constant thermal cycling and prolonged exposure to engine oil. Precision-moulded for direct OE-style installation, it provides an accurate fit around the valve cover, ensuring long-lasting sealing performance and making it ideal for routine servicing, engine repairs and valve cover replacement.

What This Product Does:

Creates a leak-free seal between the valve cover and cylinder head.
Prevents engine oil leaks.
Protects the valve train from dirt, moisture and contaminants.
Maintains correct engine oil pressure and lubrication.
Supports reliable engine operation.
Restores the original sealing performance of the engine.
Provides direct OE-style fitment.
Forms an essential part of the engine sealing system.

Symptoms Of Wear Or Failure:

Engine oil leaking from around the valve cover.
Oil burning smell from oil contacting hot engine components.
Oil residue on the cylinder head or engine bay.
Visible cracks or flattening of the gasket.
Smoke from the engine compartment caused by oil leaks.
Oil contamination of surrounding engine components.
Low engine oil level due to gradual leakage.
Hardened or brittle gasket material.
Persistent oil leaks following extended engine operation.
Reduced engine bay cleanliness.

Why Replacement Matters:

The valve cover gasket is continually exposed to high engine temperatures, pressure changes and constant contact with engine oil. Over time, the gasket material naturally hardens, compresses or cracks, reducing its ability to maintain an effective seal.
A deteriorated gasket can allow engine oil to leak from the cylinder head, creating unpleasant burning oil smells, contamination of engine components and the risk of oil reaching hot exhaust parts. Continued oil leaks can lead to reduced lubrication, increased maintenance costs and unnecessary engine wear if left unresolved.
Replacing a worn or damaged valve cover gasket restores the engine's sealing integrity and helps prevent oil leaks, ensuring reliable lubrication and a clean engine bay. The OE Match replacement provides factory-style fitment, premium heat-resistant materials and long-lasting durability, making it the ideal solution for Porsche servicing, engine repairs and preventative maintenance.

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.
