    Here is a look into a 2002 PCV grommet hole after about 10k miles with new valve gaskets service. Prior, this hole was gunked before changing the PCV valve last year. The new valve seems to be working fine, but you can see some cack droppings starting to develop down inside the cover hole.

    Are most people replacing because this part fails and throws a code, or age, or if your pulling stuff near it it’s a good idea to just change it out? Thanks

    I've never actually heard of 1 failing. I replaced mine because it was 17 years old and it's a $10 part. It was pretty nasty too.

    Oh ok. Has anyone here ran catch cans? Cats on the 4runner page were all about them, keeps stuff cleaner, but also lots of nay sayers. Mostly boosted engines that ran them but the theory seems sound.

    Mine (PCV) was all gunked up when I changed it during the valve cover gaskets replacement at 150k miles. Probably had been clogged since 80k miles when I noticed a black soot ring around the PCV area. Didn’t pay much attention to it and drove it another 70k miles which probably lead to early failure of the VCGaskets/tubes.

    Here is a good link which explains things better.
