'93 Camry V6 (3VZ-FE), how 2 replace spark plugs w/o removin

[Vibroseis]

Hi all. I'am a first time camry owner who has done most of the maintenance/service on my previous vehicles-- mainly domestic-- by myself.
So here's my question:
Is it possible to change the 3 spark plugs in the rear bank without removing the intake plenum?

Today, while at the Toyota parts counter in trying to get an intake plenum gasket, the service tech tells me that it's not necessary to remove the intake plenum to replace the spark plugs on the rear bank. He said that the job could be done by being creative with some extensions and universal joints. He said that it's far to much trouble to remove the intake plenum and that the job should not be taken lightly.

How many of you had success in replacing the spark plugs on this engine and which method did you use? Any tips are greatly appreciated. Thanks.

maybe if you loosened it and turned the engine fwd,

i would love to see someone change those spark plugs without taking the intake off

why are you getting another pleanum gasket, its doubled up metal, should be good?

i also wanna change my plugs on my 3vzfe, is this process hard? is it possible to break anything or seriously mess it up

[wontonjohnny]

also do you think those iridium plugs are worth it or should i stick with platinums?

[Nick]

the worst part about it is the egr tube and the mounting brackets for the pleanum,

when i changed the valve cover gaskets on my 92 v6 we bent the egr tube down, it took us a few hours with every bit of leverage we could find to bend it back up

i think it might be possible, try putting a lon extension on a wrench, then a flex, then an 8-10" extension and the spark plug socket, actually you might have to assemble the whole last part in pieces, putting the socket on the spark plug, then maybe a few 4" extensions (just cuz you can't really get the angles)
