Engineered from high-quality gasket materials capable of withstanding continuous exposure to engine oil, heat, pressure fluctuations and vibration, the timing chain cover gasket plays a critical role in protecting the timing chain assembly and preserving proper engine lubrication.

What This Product Does: 
  • Creates a leak-free seal between the timing chain cover and engine.
  • Prevents engine oil leakage from the timing chain housing.
  • Maintains proper lubrication of timing chain components.
  • Protects the engine from oil contamination and loss.
  • Helps preserve correct engine oil pressure.
  • Supports long-term reliability of the timing system.
  • Contributes to clean and efficient engine operation.

Symptoms Of Wear Or Failure:
  • Visible engine oil leaks around the timing chain cover.
  • Oil residue on the front of the engine.
  • Oil drips beneath the vehicle.
  • Burning oil smell from oil contacting hot engine components.
  • Low engine oil levels between services.
  • Oil contamination of surrounding engine components.
  • Accumulation of dirt and debris around oil leak areas.
  • Oil pressure warnings in severe cases involving significant oil loss.

Why Replacement Matters:

  • Timing chain cover gaskets are exposed to constant heat cycles, engine vibration, oil pressure and ageing. Over time, gasket materials can harden, shrink, crack or deteriorate, reducing their ability to maintain an effective seal.
  • A failing gasket can allow engine oil to escape from the timing chain housing, leading to oil loss, reduced lubrication efficiency and contamination of surrounding engine components. If left unresolved, significant oil leaks can contribute to low oil levels and increase the risk of accelerated engine wear or costly repairs.
  • Replacing a worn timing chain 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 timing chain assembly.

Product Information
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.
