Well my brother in law finally hit 110K and since I was already doing major maintenance, I decided to replace the PCV valve. This procedure is for the 2010-2011 Camry 2ARFE but should apply pretty equally for the most part to 1ARFE and 2ARFE equipped vehicles. This DIY will cover removal of the intake manifold, fuel rail, and PCV Valve, but will help those looking to replace the cowl or wiper components. Including breaks and the time to take pictures, this DIY took me about 5-6 hours to complete. Expect the novice DIYer to take a solid day. This job was pretty difficult the first time around. I would not recommend to do this unless the vehicle has at least 100K miles.

Warning: A hot engine can cause burns. Be sure the vehicle is cool before attempting this repair
Caution: Prior to removing the intake manifold, Toyota advises to close the ACIS flaps. To do this, you are supposed to connect the ACIS control harness to battery power and close the flaps. I found this was impossible to do in the space provided. Additionally, since the ACIS flaps should reopen automatically based on temperatures, there is no way to accomplish this using Techstream. Instead I closed the flaps manually using the procedure below.
Note: I did not remove the throttle body completely when doing this repair. If removing the throttle body, make sure to have engine coolant available.
Let's begin!
1. Park your car on a level surface, shut the engine off, and open the hood.
2. Remove the engine cover. Lift up the engine cover by grasping it pretty much anywhere and pulling straight up. Place the engine cover to the side.
3. Remove the wiper arms. Using your 3/8 inch drive and 14mm socket, remove the plastic nut securing the wiper arms to the cowl. With your hand near the nut end of the arm, push downward to release the arm from the wiper control unit. Set the arms aside.
4. Remove the upper wiper cowl. Using your stubby Phillips head screwdriver, remove the small clip located at each end of the wiper cowl. Separate the wiper cowl from the windshield seal extension and remove the wiper cowl.
Note: If the outer end of the clip spins or the Phillips head center keeps spinning, hold the outer portion with your hands and unscrew the center WITHOUT pressing downward.
5. Remove the wiper control unit. Depress the center and release the electrical connector securing the wiper control unit to the lower cowl. Using your small flathead screwdriver, separate the wire holder on the lower coil and remove the harness from the lower cowl. Using your 3/8 inch drive ratchet and 10mm socket, remove the 4 bolts securing the wiper control unit to the lower cowl. Set the unit aside.
6. Remove the lower cowl assembly. Using your 3/8 inch drive ratchet and 10mm socket, remove the four 10mm bolts securing the lower cowl assembly. Then switch the 14mm socket, and remove the four 14mm nuts securing the lower cowl to the strut tower. Lift the cowl from the car and tilt it slightly downwards to access the remaining harness clip. Using your flathead screwdriver, depress the sides of the holder one at a time and remove it from the cowl. Set the cowl aside.
7. Undo the upper airbox, from the lower airbox. Using your 3/8 inch drive ratchet and 10mm socket, loosen the two captive screws securing the upper airbox to the lower airbox. Lift the driver side of the upper airbox up and pull outward to disengage the rear claws.
8. Remove the breather hose from the intake manifold. Using your angled or straight needle nose pliers, depress the ears of the hose clamp and slide the clamp down the hose. Then either pull the hose off with your hand, or use your hose pliers to carefully twist and pull it off.
9. Remove the MAF sensor and EVAP VSV sensor connectors. Depress the center release and carefully pull the connector of the sensor and VSV.
10. Remove the EVAP VSV from the intake hose. Carefully grab the VSV and rock it up and out of the intake hose holes.
11. Remove the intake hose assembly. Using your 3/8 inch drive ratchet and 10mm socket or 10mm wrench, loosen the set screw for the intake hose clamp until the clamp is loose enough to easily remove the hose. Remove the intake hose assembly with upper airbox.
