In today's video I will show you step-by-step how to change the valve cover gaskets on a 2004 Lexus GS 300. The process is very similar for a variety of Lexus/Toyota vehicles with the 2JZ-GE Inline-6 cylinder engine (VVTI or Non-VVTI) as listed below:

2nd gen. Lexus GS 300 (1998-2005)
1st gen. Lexus IS 300 (2001-2005)
1st gen. Lexus SC 300 (1992-2000)
Naturally Aspirated (NA) Toyota Supra (1993-1998)
7th & 8th gen. Toyota Mark II (1992-2000)

Valve cover gaskets are one of the most common services performed on these cars especially as most of them are pretty old now. Signs that you might need to do this include misfires due to oil leaking into the spark plug holes and fouling them, a burning oil smell from the engine bay from oil dripping onto the exhaust manifold and of course, a drop in oil level over time.
