Diagram ref no 2

The seal ring creates a tight seal at the heat exchanger connection, helping prevent exhaust gases from escaping before they enter the rest of the exhaust system. A correct seal supports proper exhaust flow, reduces unwanted noise, and helps maintain engine performance.

Functions
•  Seals the connection between the heat exchanger and cylinder head
•  Helps prevent exhaust gas leaks
•  Supports correct exhaust flow and back pressure
•  Reduces ticking, blowing, or leak-related exhaust noise
•  Helps maintain turbocharged engine efficiency
•  Provides an OE Match replacement for the original exhaust seal ring
•  Suitable for heat exchanger removal, replacement, or exhaust system service

Exhaust seal rings are exposed to extreme heat, pressure, vibration, and corrosion. Over time, the original ring can flatten, crack, burn through, or lose its sealing ability. A failed seal ring can cause exhaust leaks, ticking noises, fumes, poor sealing at the heat exchanger, and reduced exhaust system efficiency. Replacing the seal ring helps restore a tight, reliable exhaust connection.

When to replace
•   The heat exchangers have been removed or replaced
•   There is an exhaust leak at the heat exchanger connection
•   A ticking or blowing noise is heard from the exhaust/head area
•   The old seal ring is crushed, cracked, burnt, corroded, or missing
•   Exhaust fumes or soot marks are visible around the joint
•   Engine or turbo exhaust work is being carried out
•   As preventative replacement during exhaust system reassembly
