Removing/Spraying Valve Cover, need help, will do how-to article Options

[DSRT-FX]

hey 6gc'z,
Been on 6gc.net since last year, and i've always wanted a red top. Much like a Honda Type R and a Nissan Skyline engine. Although toyota are alot better Nwayz i've got a few dillemas:

i. How in the world do you remove the valve cover? (4 bolts below the ignition leads?)
ii. Do I need to remove the spark plugs first? and other wiring?
ii. If I do remove the valve cover is there going to be an abundant volume of oil threatening to devour me? lol
iii. When I need to put it back on do I need to replace the head gaskets?
iv. Any other information i need to know?

Thanks for your time guys. If all things go well i'll be definately making a how-to article on this =] -R

Hey 6gc'z,
Thanks for the quick reply, hopefully all goes well tonight, im just still a little skeptical about the whole oil leak when I pull out the vavle cover. Thanks for clarifying x_itchy_b_x, I forgot to mention I have a 5SFE engine. The australian 6th generation celicas all have them except for the GT-FOUR. Basically, all I need to do is unplug and remove all wires that are in the way. Find 30mm sockets to unscrew the bolts on top and viola! Do you guys recommend I should make a how-to article on this. Seems like everyone has already accomplished this.? Suggestions?

edit: while we're here, does anyone know how to remove the heatshield

Akimbo: From my recollection, you have to remove 12mm bolts (6 in total) and unplug a sensor of some sort thats connected to the factory headers. Definately use WD-40 for the bolts as thay are very hard to unscrew and you wouldnt want to snap of any bolts or sockets from my past experience
