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.

I keep getting comments saying I forgot to mention two hoses while removing the throttle body - I did not because I never removed them. If you watch the video, you will see those two hoses are still attached. This is because I am not completely removing the throttle body, just turning it over and setting it aside so I can access the valve covers.
How long does it take to change it?
@@sonypierre4799 I would say around 1-2 hours.
Helpful note:
The PCV valve (positive crankcase ventilation valve) should be changed approx. every 20-30k miles. A bad/stuck PCV valve can result in oil leaks due to increased crankcase pressure, rough operation or stalling. It’s a very cheap and easy part to replace, so don’t overlook it!
Following these steps made me convident that I can do it!

Great guide! I followed this to the tee! There was one hose you forgot to mention to remove. It attaches to the throttle body and is right below the accelerator pedal position sensor.
Glad you found the video helpful! I didn’t mention the water bypass hose because I didn’t remove it - it’s unnecessary with this method because we aren’t actually removing the throttle body, just turning it over so the valve covers are exposed. You can see it’s still attached at 3:26.
Thanks for watching! :)
@@theautochap ahh got it, makes sense now!
you forgot to mention a couple of hoses when taking off the throttle body
I didn’t forget any hoses. I have answered this question in multiple comments on this video - I didn’t have to take off all the hoses because I’m not removing the throttle body, just setting it aside to access the valve covers.
Hi. Great video. If I am not replacing the plugs/coils, can I leave those in as I change the valve cover gaskets?
Hi! Yes, you can most definitely do the gaskets without changing the plugs, it might be a little cumbersome with the wires getting in the way, but not impossible for sure.
Thanks for watching! :)
@@theautochap Thanks!!
You saved me 1200 bucks. Thanks so much for this video. After replacing them, I am getting oil bubbling up from the exhaust manifold gasket and pooling below the valve cover gasket. It is NOT coming from valve cover. Any ideas? I read somewhere that next to the exhaust ports there are square chambers where oil might have gone into when the valve cover gaskets were leaking. Before I take off the exhaust manifold and look, is this a possible scenario that you may have run into before? Thanks
Head gasket?
It was just residue that has since burned off. No leaks.
How long did this process take?
This process should take around 2 hours. Maybe a little more if the hoses are old and glued on due to the heat.
Thanks for watching! 😊
Wish i never got this car going from a 2004 monte carlo ss to this is annoying cuz eveything seens so fucking garf yo get too
Great video! Thanks. Only wished you had explained why replacing the pcv valve is so important. If that goes bad, a lot of REALLY bad things can happen to your car! 😢
Hello! Thank you for the call out, normally I speak a little in the beginning about why I’m performing a certain service but looks like I forgot about the PCV valve this time. I’ve added a comment and pinned it to the top, that should serve as some helpful info to whoever is watching this video.
Thanks for watching! :)
