Throttle Body Cleaning

[message]

Figured I would clean the throttle body as I've noticed a little irregular idle as of late so I did the full removal, which includes a coolant line and a couple fasteners.
To start it didn't look very bad until I had it removed saw the back side. I didn't get a picture of it but the rag clearly shows how much crud there was. I literally could have scraped it off with a putty knife it was to thick right behind the butterfly.

Next I checked out inside intake and noticed a dark area in the back. Upon closer inspection I found a puddle of oil hanging out which I wiped up with a clean cloth and a stick. I'm wondering if I should replace my PCV valve or if this is simply due to oil vapor?
I've been reading about installing an oil catch can which from the sounds of it doesn't take much to do... What do you guys think?

I've been wanting to clean my TB lately. When you did this did you manually open the butterfly after everything was unplugged? I've read other posts where that created big problems, started throwing codes and what not. Were there any gaskets that you had to replace?

UPDATE:

I went ahead and just jumped into the TB cleaning. Disconnected the battery, took off the intake stuff, and the cover on top of the intake. There was nothing to it. If you've ever taken anything apart and put it back together, this is all that's involved. Just make sure you disconnect the battery, unplug the electronic control harness thing from the throttle body itself, disconnect the coolant line, and start unbolting, then the throttle body just pulls off. Easy peasy.

I was worried about manually opening the butterfly possibly screwing something up, but with everything disconnected the computer has no way of knowing so--just make sure everything is disconnected...which is necessary if you're planning to completely remove the TB--and there's really no reason not to. If you're gonna leave the TB on the engine in fear of messing up the gasket, just make sure you disconnect everything (battery, TB wiring harness thing) and you *should* be good to go and be able to manually open it without screwing anything up.

Put everything back on in reverse order once you've cleaned it all up and there you go! TB cleaned!
