PCV Valve Replacement Instructions-4.7L

The foam cover appears to be:
Toyota 12236-50010
Cover, Ventilation Valve

 

The FSM for our 04 calls for 20ftlb and rotate as shown below !

 

Found the foam cover thanks to @w666

The PCV hoses differ between V8 and V6. Had to do some digging to ensure I got the V8 hose and not the V6.

For the record, part numbers for a new V8 PCV hose, hose clamps, and foam cover:

 

I had a feeling that grommet would be a PIA. Had a new PCV installed, the grommet leaks like crazy. Crikey.

 

So let's suppose you find a valve cover from a later generation truck that threads in. Could you just swap valve covers to be rid of the grommet?

 

I don't see why you couldn't if everything lines up.

Another member on here - @txagg ? - went through the "generational valve cover" swap, I think? I'll see if I can dig and find that. It was someone within the last 6 months, around the same time I did my gaskets. If I can find in the next 3-5 mins I'll update this reply.

 

2006 threaded...gunked up but still sounded good. Quick and easy. Let it warm up to go get beer and still a little tough to get loose. Foam was crumbly too but able to put back on.



Sorry, phone decided to focus on the gloved hand...you get the point. Having issues with it connecting to laptop, looked a little more clear on the handheld computer.

 

Hello Everyone!

I am new here and would like to ask if there are two PCV valves on the 4.7 V8. I see the one which is being discussed but there seems to be another one on the other bank on a 2002 engine which looks like the threaded valve. Any ideas?
Thanks!

 

There's only one on my 4.7, on the driver's side. I've got the VVTi 4.7 that's in the '05-'06. Can you snap a pic of the PCV you're looking at on your truck's 4.7?

 

I believe their speaking of the one Mr BumbleBee was showing in this thread….https://www.tundras.com/threads/tundra-2000-charcoal-canister.121156/
On an 04, it's part of the crankcase ventilation system(PCV) system. Simply another path for blow-by gases to be pumped back into the cylinders for another shot at combustion.

 

Do you know if it's actually valved, or is it just a vent?

 

On my 04, just a vent thru that 90 deg fitting. Not sure why Toyota Engs felt driver side needed an actual PCV unless it was there way thru throttle body to intake

 

Yeah, dunno. I guess I just glanced over it when I did all my gaskets. Mine has it too. Huh. But I'm 90% positive it was just a crankcase vent, not a valve.

 

Replaced mine today.
Pretty tight but do-able.
After removing the hose, I was able to get the closed-end of a 7/8" wrench over the old one to remove it.
Didn't look bad, but since I already bought a new one & it was cheap, I swapped 'em.
It's gotta be my imagination . . . but the truck seems to run a tad better . . . felt a little 'crisper', but I can't see how that could be.

 

I don’t recall seeing any schedule to replace on our trucks but back in the day most maufacturers recommended replacement at 30K IIRC.
