PCV Valve 3400

Ok, I know this has been asked a ton, but where exactly is the PCV Valve in on the 3400. Is it to the right of the Engine oil cap on the valve cover, or is it in front of the throttle body..that would be the IAT sensor right?

I do not want to lock the engine up, so I want to dump Seafoam in the right place. Do you dump in it the PCV Line, or just in the hole?

Thanks Guys..pics would be awesome.

pcv is right at the far right of the front valve cover.

alright, what's your intent. Clean the TB / Intake path ("do you just dump it in the PCV line"), or are you trying to clean the crank case for an immediate oil change ("or do I just drop it in the hole")
