Removing the side bracket that holds the plenum is a must and was the only thing i really removed...... so all you mechanicaly inclined people should have no problem in doing so, with a bit of patience and being creative with the tools (a wooble ext.) and your hands they do come off easily I may say. I do wonder why one of my plug cavities had engine oil in it, very odd, could that be seal down the plug shaft? if someone has some insight on this post up. I cleaned up as much as i could of the oil in the cavity and was able to clean it all when I removed that plug and it drain down to the cilynder, lt had to be done, the plug was tight as factory. I replaced all 6 plugs and next weekend Im going to be removing that one again to check inside.

Did my plugs today, turned 100K miles!
Last Friday I turned 100,000 miles (highway miles) I had already bought the plugs so this morning I went for it and decided I was gonna try and remove them (passanger side) without having to remove the plenum, the throtle body or any other stuff as per the service manual. I DID!

Very good info!

Even if somehow the spark plug O-ring was bad there can not be oil shooting back from the cylinder into the cavity; seems like either some oil was left in there from the factory or your second guess: a pinched or poor seal of the rocker gasket around that plug cavity. Anyone have a pic. of the inside of a rocker cover?
I don't think the oil is from the cylinder. It's from the valves and the oil splashing around under the valve cover. It should be an easy and cheap fix. The O-rings are probably $10 - $15 and you just have to remove the valve cover to access them. Probably not a bad idea to take care of the valve cover gasket while your at it.twinblown wrote:Even if somehow the spark plug O-ring was bad there can not be oil shooting back from the cylinder into the cavity; seems like either some oil was left in there from the factory or your second guess: a pinched or poor seal of the rocker gasket around that plug cavity.

Edit: I think what you're calling the rocker cover, we're calling the valve cover.
Correct I am calling the valve cover, rocker cover. I understand it would be a easy fix it's just that to remove the pasenger side cover involves removing plenum and a whole other stuff, time consuming and I don't even wanna know what the dealer would want for that. Anyways I am hoping the oil was somehow left over at the factory and I do not have a leaky seal. I'll check on it this weekend.

I used every combo of extensions I had to change mine. It varied so much on the passenger side, and was so much trial-and-error, there is no way I can remember which combo I used for each cylinder.WheatBread wrote:any tips on doing this without taking the plenum off? what size wobble extension did you use? any other extensions needed? how did you get the coil pack out?
The coils come out pretty easy, except the front one on the passenger side. The coil is too long, with the intake in the way, to pull straight out. I ended up seperating the top of the coil from the coil boot and got it out that way. I dont recommend this though, I partially tore the plug boot in the process.
The best "tool" to help with the job was about a 5/6 inch cutoff piece of fuel hose. It helped in removing the old plugs once I had them loose, and was priceless in getting the new plugs in with confidence that they werent going in cross-threaded.
I would recommend you remove one coil pack from the driver side and take a good look at how it is assembled, the coil pack does seperate from the rubber boot, if it did not it would be impossible to remove it (the passenger side ) without removing the plenum. I used a 3 inch wobble ext. a 8 inch and a 3 inch regular extension. As far as the plug socket there are some out there that have a rubber inside and that will hold the plug in place when you remove it; when you put it back I did not use the rubber with fear of the rubber satying stuck on the tip of the plug and instead placed a long piece of folded aluminum foil all along the inside of the plug socket to keep the plug from falling off during installation, once you have screwed the plug a bit pull out remove the piece of aluminum and torque the plug normally. Hope this helpsWheatBread wrote:any tips on doing this without taking the plenum off? what size wobble extension did you use? any other extensions needed? how did you get the coil pack out?
