pcv valve on a 3400
 

you guys might yell at me because theres already a couple threads about this... but, i cant seem to find a straight answer

where is the pcv valve located? is it before the throttle body? or is that the IAT?

i ask because im planning to do a round of seafoam but i dont want to pour it in the wrong place :P

heres a pic so you guys can help me out. is it number 1 or 2?

It's number 2, number 1 is your mass airflow sensor I think.

If its liquid seafoam it goes in the oil and gas tank if u want. Spray seafoam goes into the intake. So if its the liquid then #2. If its spray then #1.

#1 isn't really anything.. just part of the PCV system. The PCV valve is 2. The MAF is near the airbox.

Pouring anything the PCV is just like pouring it into the oil. Goes to the same spot, it just takes longer to go in the oil VIA the PCV
