This OE Match engine cam cover gasket and OE Porsche bolt kit is a complete replacement sealing kit for Porsche 991.2 Carrera models. It includes one OE Match valve cover gasket and genuine Porsche cam cover bolts, giving the required components to reseal both engine cam covers.
Fits:
Porsche 991.2 Carrera 2016 - 2019
Diagram Ref No 9, 8 and 13.
The cam cover gaskets seal the joint between the cam covers and the cylinder heads, helping prevent engine oil leaks from the upper engine area. The OE Porsche bolts secure the cam covers in place and provide the correct clamping force needed to maintain an even gasket seal under heat, vibration, and normal engine operation.
Functions
• Reseals both engine cam covers
• Helps prevent oil leaks from the cam cover / valve cover area
• Seals the cam cover to cylinder head joint
• Helps maintain correct clamping pressure across the covers
• OE Match gasket solution with OE Porsche fixing hardware.
Why Replace This Kit?
Cam cover gaskets are exposed to constant heat cycling, engine oil, vibration, and age-related wear. Over time, the gaskets can harden, flatten, crack, or lose their sealing ability, which may result in oil leaks around the cam cover area. Replacing the gaskets together with new OE Porsche bolts helps restore reliable sealing and reduces the risk of repeat labour caused by reused or worn fixing hardware.
When to Replace This Kit
• Oil leaks are visible around the cam cover / valve cover area
• There is a burning oil smell from oil reaching hot engine or exhaust components
• Oil residue or drips are found around the upper engine area
• The cam covers have been removed during service or repair
• The original gaskets are hardened, flattened, cracked, or leaking
• The original bolts are corroded, damaged, stretched, or previously removed
• The engine is undergoing top-end service, leak repair, or preventative maintenance.
Where it fits on the car
This kit fits on the engine cam cover / valve cover areas of Porsche 991.2 Carrera models. One gasket is used for the cylinders 1–3 side and one gasket is used for the cylinders 4–6 side, with the included bolts securing the cam covers to the cylinder heads according to the factory tightening sequence and torque specification.

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.
