Introduction If you own a Holden Commodore 1996 - 2001 fitted with the V6 Ecotec engine, and find the engine smoking and/or burnt oil smells being drawn into the passenger compartment after an extended period of driving, you may have faulty rocker cover gaskets.
These gaskets only have a finite life. The high heat causes them to melt, making the seal ineffective, allowing engine oil to leak out and flow onto the exhaust headers, creating the burning oil smell. In this state, your vehicle will also start to lose engine oil, requiring top-ups.
This article details how you can replace the seals yourself, rather than taking your car to a mechanic and paying for a relatively simple job.
Requirements: About one hour
10mm,8mm socket and driver set
Rocker cover gaskets to suit (one if only one side is leaking, two if both)
Procedure:
