valve cover gasket replacement ?
im leaking oil around the valve covers so its time to get in there and replace the valve cover gaskets. i want to make sure i have all the parts i need before i tear it apart. so is there anything else i should replace when i've got the throttle body and intake off?

our cars have two separate valve covers. one for each cam, hence two gaskets, hence no spark plug o-rings.
i say replace the valve cover gaskets. i would get the toyota original ones. do the plugs as well. i used denso PK20R11. thats the NA supra plugs. when i did my plugs i found PK16R11 plugs which is weird because they are turbo plugs. oh well.
check around the distributor for any leaks. there is a small metal pan underneath the distributor. if it has any oil in it then you might need the distributor o-ring as well.
while everything is apart clean the throttle body and the upper intake manifold. if you order the EGR delete plate you can also do that. you have to remove the egr valve to take off the upper intake anyways. do a search of how to eliminate egr.
good luck. you got my number. if you need help let me know.

there are no tubes to seal the valve covers from the plugs. there is a small tray between the two valve covers that supports the spark plug wire but there is no need for actual seals there. its is not a nissan where the spark plug hole actually goes through the valve cover. our cars have two separate valve covers and those extra "tube gaskets" are a waste of money.
you can use a mk4 supra NA valve cover gasket on the 92-97 SC300 no problem.

alright.. let me bring this back from last year
I just visited the Sewell Lexus website. I saw the engine overhaul gasket kit; I thought that would include what you guys were referring as "rubber grommets" for spark plugs.
I don't see it... please assist me. I would like the leak/problem on my plugs to stop.
Thanks
