ok so yesterday i went to replace my pcv valve, our computer at work pulls up a part number and i got the valve for my car.
because i do not have any sort of manual for my cart went to the repair guide on autozone.com it says the pcv valve is located on the rear camshaft cover but i looked all over each camshaft cover and did not see any sort of pcv valve.
can anyone get a pic or explain where its at, i feel kinda dumb not being able to find it lol
The 4A-GE 16V doesn't use a PVC valve, so you can stop looking for it
ha i had a feeling that was gonna be the answer i was gonna get. that sucks that there is a so called part number for it.
so does the 4age utilize a pcv system? if so how does it work?
Yea lots of parts store listings confuse the 4AFE with the 4AGE. Since they were both 1.6L, DOHC, and both in Corollas, it gets a little sticky. I've found it almost impossible to get a throttle body gasket that's for the 4AGE and not the 4AFE.

ya i see what you mean! ill have to keep an eye out. it kind of sucks cuz at my work they have every trim level seperated

well yes and no.
the 4age definitely has a positive crank-case 'breather' on it.... per say.
the hose that runs from the intake cam cover to the middle of the intake manifold is actually the breather. The catch is that most people think it runs straight to the manifold and that's it.... well, that's wrong as well.
the intake manifold has a chamber built in and the "PCV" system actually routes to the throttle body... where the pressures are much lower than in the intake manifold itself.
the problem with this system (which is why the 20V probably had a true PCV valve) is that the passageway in the cam cover can easily get covered with **** and cause blowby....

well that kinda seems like a pain in the ass setup instead of having an inline pcv valve lol.
is there anyway to make sure it is flowing freely such as poking something down the passage way or is it kind of a waste of time cause its just gonna get clogged up again
you can pull the oil fill cap and look to see if you notice a lot of dark (I mean black.... a bit of brown is no big deal) build up on the filler neck, underside of the cap, or shine a flashlight in and see on the head... if it all looks relatively clean then the pcv system will be clean (it does use something similar to a "windage tray" that's built into the underside of the intake cam for the PCV system...... if it looks dark and/or you see build up you might consider pulling the cover and taking a closer look with it off.

I've found that at several stores. Many will have both 4afe and 4age numbers listed for both engine in all the models, usually differentiated in some way (mostly rather cryptic) in the part description.
^^^ that's just the way all parts stores are.... it's actually pretty easy to figure out if you just pay attention.... unfortunately many parts stores don't pay enough to retain good employees....
for instance if you look up (as aforementioned) a throttle body gasket.... typically the system will have you go through to choose 1990, then Toyota, then Corolla (maybe have it broken down by DX, LX, SR5, GT-S)... but this last piece really doesn't do much.... usually the system is smart enough to pull in what motor is in there... but that doesn't mean that the parts are loaded that way. So then you just need to look into the description, and that may depend on what the company sent in as the description... might be by "4afe", "4age".... or even by vin code(s).... and every now and then there are variances between Japan and Canada/US built (which is the first letter in your vin).
they will do the same thing on american cars too.... looking something up like a u-joint on an 80's chevy can be horrible.... it will literally have like 25 listings based on rear end, wheel base, motor, transmission, etc.

Exactly. Well, its easy to figure out if you have experience, anyone fresh will just look at the first part number and definitely say that that is it. In my current job, I'm the only person who remains, just over the course of a year three sets of management, every other employee has quit, or been fired. The pay is pretty good for a college student but its rare to find someone with experience, and frankly worth a damn, willing to work for that.
The u-joints aren't too bad, most part numbers end up being the same so there aren't too many problems. The current generation of gm trucks, just to look up brake pads is ridiculous. They vary based on, number of caliper pistons, location of the caliper, 4ws, GVW, rear end, HD, etc...
