    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?

    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 :notsure:

    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.

    Could be partly imagination, partly reality. I swear my Tacoma always drives better - smoother, quieter, more pep - right after an oil change. I'm sure most of it is me knowing it's been taken care of. But I think it really is noticeable when everything inside the engine has fresh, uncontaminated, un-broken-down lubrication.

    My new PCV and grommet will be in my hands by the end of today. Another project for the weekend unless I decide to go camping. I've had this thread bookmarked.

    I don’t notice anything after oil changes on my Tundras but my 2005 Suburban has noticeably less “vortec-tic” when the oil is new.

    Did this yesterday. Not sure if it had ever been done before, but it was really pretty clean. Replaced it anyway. Gasket is definitely a pain, but I got it out without dropping any bits into the valve cover. If nothing else, I feel better knowing there's a fresh gasket in there that'll take many years to get as hard and brittle as the one I pulled out.
