3VZE PCV Change
1992 SR5 2WD 3VZE
PCV Replacement: (20 - 30 minutes).
Before you begin, make sure you have a set of long needle nose pliers (LONG - maybe foot long or longer with curved up end if possible). Don't start 'til you've got 'em. I even went back for a longer pair for the next time I change it.
PCV Location: Passenger side under Plenum: directly beneath the second "T" in ToyoTa imprinted on plenum (at least it was for mine).
Raise (6" - 8 ") 2WD truck up on ramp on passenger side only. For this short man (5’6”), this will change the angle you are working to your sight advantage and less back strain. Also, you will need a good light source (drop light) as this is an area that light is not going to reach without assistance.
Use 12 mm wrench to loosen/remove fuel line (be careful not to drop the aluminum washers).
After numbering/marking the various vacuum hoses (approximately 7 - at least it was helpful for this ole man) blocking the PCV, pull them off their pipings and move them out of the way.
Note: PCV Hose from plenum to the PCV is shaped almost like an "S" or actually more like a "?".
Use LONG needle nose pliers to remove PCV hose followed by the PCV (rock the PCV back and forth while pulling it up to remove).
Reverse procedures for replacement.
Note: When changing the grommet, attaching hose to PCV with retaining clamp and then inserting it into PCV grommet may be easier to do than attaching hose after PCV has been inserted into grommet.

Also, a "Steve's PCV valve mod" is located in another thread...looks promising..might be worth a try...
