Did the Seafoam today before oil change (4.3L V8 PCV Pics included)
I was a little confused at first about exactly where the PCV valve was. Once I had that figured out I ran into another problem.
Which end of the hose is supposed to be removed? The way most post read it would seem to remove the hose from where it went into the throttle body/plenium. When I did that, there was not enough suction power to take the Seafoam.
So, I left the PCV valve hose on the throttle body and it worked like a charm. My car did not smoke alot, but some. I think I repeat the treatment next oil change to be sure.
Instructions (GS 430 specfic):
I used (as per bottle) about 1/3 of a pint of Seafoam into the throttle body in this manner. The other 2/3rds I dumped into the dirty engine oil and changed it immediately after.
Wide view from driver's side (removing the engine cover is a must):
Cover removed:
PCV Location (right next to the engine oil fill, remove hose clamp here):
Leave this end of the hose attached, throttle body will suck in air and small amounts of Seafoam without stalling or flooding. Do NOT immerse the end of the hose into what ever container you are using as it will likely flood the engine.
Enjoy being Seafoamed

Besides white smoke?
The car seems to idle higher at first, but then today I noticed it dropping back to 500-600RPM range again. It seems a bit smoother and quieter, but that may just be wishful thinking.
One thing I have seen noted over and over that I DIDN'T do last night is to replace your spark plugs after this procedure. I am due anyway and hope to accomplish that within a week or so.

Oxygen sensors are usually pretty easy - the trick with them is pre-twisting the connection cable before screwing it back in. Definately a DIY job - last night when I was under the car I happily noted the rear sensor is in a place easy to get to.
In fact, while I am post-whoring and on the subject, the layout of this car is pretty nice. Yeah, the starter is in a weird place, but for most of the maintainence items it is well done (IMHO). All except that is for the oil filter. Do you guys remove your entire undertray to access that?
I cheated and "modded" the tray with a utility knife. The next change will be much easier.
