Just replaced this morning PCV on the 2008 Toyota Tundra in signature. Went with a Toyota OEM. No it did not rattle and felt like 4 times the weight of the replacement with all the crud outside/inside.
Look at this mess --- PCV on 2008 Tundra

Wow! That is a dirty PCV valve. Is this truck short tripped? What is the normal OCI?
never seen that filthy pcv valve in my life

x2! I'm glad it's getting changed!
I would take a shopvac and duct tape a hollowed out bic pen to the end and vacuum out everthing before i installed a new pcv
You can buy cool kits for that
Milwaukee is offering them now, too. But way more $ as is Milwaukee's way.
35 bucks? Nah, i like making my wife ask, what on earth do u need a pen for?
The PCV hole where it screws in was 90% closed with crud. I used my shop vac and sucked out what I could before installing the new PCV. Cant imagine it ever being changed before???
Just purchased this truck recently. Not sure of the maintenance before. Got fresh oil change/tran fluid and differentials for a base line to start. Also new cabin and air filters.
Fill cap and down look fine. I agree that its external crud --- mostly. Worst PCV I have ever replaced on "any" vehicle.
How many miles? I just replaced the PCV valve on my MDX with 90K miles and it looked and sounded great.
SERIOUSLY believe it was the original. Truck has 153,866 miles as parked in my driveway.
Appearance, rattles, and even air flow (restriction one way, free the opposite way) is rather dubious, IMO. The PCV in the Lexus (1UZ) always "tested" acceptable, per the service manual. When I had the intake apart, it was full of engine oil.
The valves are cheap enough, I just replace them every ~10k or so miles (ancient tune-up interval). I haven't looked thru the throttle body in a while

I imagine that you also replace the hose that attaches to the PCV, probably old and brittle.
Actually I didn't, sprayed out multiple times with carb/intake cleaner until clear while it was off. Not a bad idea though.
