ok so I pulled the no 1 spark plug today, it was completely drenched in oil. Now here's my question, I just found out one of my pcv lines from the valve cover on the left was almost completely clogged... do you think all that extra build up of oil in the valve covers could have caused the seals on the valves to go kaput and explain the oil leak? I can't tell for sure but the cylinder looks heavily drenched, I haven't even checked the other ones yet.
oil in plugs?

Probably the valve cover gaskets. I had the same problem. Be sure to use a little bit of FIPG when you replace them or there is a pretty good chance they will start leaking again.
Yeah, it probably is the gaskets, I just checked the last plug all the way in the back. well I didn't check it because when i pulled off the boot I saw oil all around it. The plug I did check turns out to be in perfect shape after I cleaned off the oil so it's running the correct mixture at least. I just used some carb cleaner to clean the pcv tubing until I replace it with two mini breathers. Also, quick question. Is there any way to remove that thin piece that separates the boot from the plug? There are these huge hexagon shaped things that look like what you would use to take it out but I'm not sure what they are called...
if I could get that thin piece out I could probably get the oil out and actually check the plug but as it is I don't have much room to move my finger let alone a rag.
that thing is called the 3rd engine gasket (dealer only part) if you pull those for giant allen wrench bolts out you can get a towel in to soak up the oil. when i redid mine i pulled it off and the normal valve covers scraped and cleaned the whole head surface then put a thin amount of silicone around the whole thing and then put the #3 engine gasket in and the other two but get it all done while it's still rubbery if the siicone dries before your done you might end up doing it all over again in the near future... i messed that up once

I noticed when I pulled my valve covers that there was a half an inch gap in the seal where there was no seal. I used pipe cleaners and rust penetrant to scrub the metal part of the lines till they were clean. The rubber hoses connecting the lines were and are rock solid. All I really know to do is spray some degreaser into the port and let it sit and clean it as good as you possibley can. Sorry I'm not more help but I am dealing with like minded issues. Thanks 4 reading.
The "thin piece" is often called the 3rd engine cover. You aren't going to get it off without taking your throttle body/y-pipe off. You need a large hex-head to get the bolts off, i think there are 3 or 4 of them.
Edit: you can get an aftermarket stainless steel one from SupraSport for a few bucks more than the stock one. I paid something like $33 for a stock one from Toyota.

it's a 14mm allen socket or you can use a 14mm bolt in there with some clever engineering to turn it.
i bought a full set of allen sockets at Harbor Freight Tools for like $12.. very nice quality believe it or not!

So far I've gone to harbor freight, autozone, discount, and sears and none of them carry the 14mm hex nut/ allen wrench. Everyone tells me to try Napa, so wish me luck. Thanks for the info about where to get a replacement "3rd engine cover", that product on the link looks promising.
I got mine from my frendly neighborhood Snap-On man...
I can post the number when I get home if you promise not to faint from sticker shock.

thats it... thats what i bought. i was a little off on the price, but thats it.
bonus is if you have a targa and are missing your wrench like i am, now you have a 6mm hex socket to put on a ratchet
