    Because this was really a how to install thread, not should I install thread. We still debated it anyway and good for the most part, I don't think there is anything that was left out? I think we focused more on the "should I" not "how do I"

    Isn't that exactly what this forum is for? To discuss things? As long as nobody is getting personal what's the harm in the discussion continuing? You don't like it stay out. Pretty simple.

    Yes it did, if you look at the first post by the OP, this thread was created looking for information on an install. The thread got hi-jacked along the way and the information was finally provided in post #256. Too bad it took that long for a helpful community to answer a question. Instead of answering the OP, people piled on and told the OP not to do it based on their personal views.

    Did you not give your personal view on it as well?

    Yes I got caught up in it as well, and I should not have.

    Everyone became passionate about an issue this thread was not suppose to be about. I tried to present information in a constructive way as best I could and I was getting bombarded with prove this or prove that. Others presented their views as well. The thread became destructive and I am glad it got back on track to what it is suppose to be about.

    We are suppose to be a community and if someone wanted information on big tires I would not jump on them as say don't get them, they howl, poor fuel mileage, no benefit on a regular street, waste of money etc....... If they want them fine, provide the information. Thats what we are here for. We are not here to decide what people buy and don't buy. I think we all got a little too caught up but the positive I see is that we have a bunch of forum members who are passionate and that is good. This thread did not get boring (at least in my eyes)

    I don't know why anyone is getting their feelings hurt here. We are having a discussion about catch cans. Sure, there is ribbing going on, this is the internet.

    Information on why you should or shouldn't have one is presented. We are all grown ups and can take that information and decide if it's the right mod for ourselves.

    I agree, and I hope no one got their feeling hurt, I did not, but the thread was really about does anyone know how to install. We should have started another thread, "are they valuable" or "should I get one" you know like that and then went at it haha. But there is probably too many of those already.......

    I'm saying that because the OP's question was kind of buried.

    only problem with our engines is that the 3.5 has 2 lines that run from the top front on passenger side, and to rear on drivers side, you would need to dump both lines into a catch can, and then split the single output to a double, and back into the intakes, or run it into one, and hope it does not alter performance charateristics..

    our engines suffer from high angles causing oil to pool at the back of the drivers side head on a steep incline, it will fill the back of the valve cover, and blowby, as well as crankcase pressure will force the oil that pools at the back of the head directly into the intake manifold (this one dumps into the intake after the throttle body), the other PCV valve is taken from the front of the passenger valve cover, and dumps into the main intake line prior to the throttle body, so on a steep slow descent it will pool with oil, crankcase pressure will again, force the oil up and into the intake tube, and eventually into the manifold causing your engine to smoke.. a catchcan at the very least will catch this oil before it gets to the intake, and allow you to dump the oil manually, or run a drain line from the catch can to the oil pan. thus removing/reducing the possibilty of smoking engine exhaust on a hill and possibly fouling some plugs.

    Pic of the location of second PCV? and where it connects?
    I thought is only one PCV there.

    Thanks for the pictures. I thought I needed another catch can.

    The passenger side is referred to as the clean side. There should be no oil there (or very little). I don't think there is a PCV valve there. That hose that comes off the valvecover on the passenger side connects to IN FRONT of the throttle body, in the air filter passage way so there is very little vacuum there and very little of anything is pulled out.

    The drivers side is the dirty side. Out of the rear of the valvecover and into the intake manifold where there is high vacuum. This is where there is a lot of draw.

    I just went outside to solve my curiosity and I pulled the hose on the passenger side and it was dry, no sign of oil anywhere. I then disconnected the input side of my catch can and there was oil there.

    I think its only the drivers side you have to worry about. If anyone wants to call Toyota to verify if there is another PCV valve but I don't think so. I tried looking it up on line but could not find anything.

    Correct me if I'm wrong but my understanding was the fresh air portion of the PCV system (inlet after air filter but before throttle body) provides some pressure and fresh air to the outlet portion of the PCV that is connected to the outlet for crankcase gas/blow-by/etc.

    OK so I was troubled and I didn't want to say there was only one PCV when there is the possibility of two so I did call Toyota. They confirmed there is only one and it is located on the drivers valvecover in the rear. They actually call it a ventilation valve and the part number is 122040P020.

    I think you are right and thats why its clean there. I think the air goes in there and exits the PCV side. So we don't have to worry about anything coming out of there, I don't think we should. BUT, there is no PCV valve there just confirmed by Toyota. Only 1 PCV on this vehicle. Good observation

    Now if I can only find some quality hoses like the OEM gray hoses to put on my can. The hoses I have on there now are cracking at the nipple connection. Need to replace soon before they crack thru and have a leak.

    You should check out my vid to see what I used. They should last a very long time and easy on easy off for service.

    Does anyone have a pic of the clutch master cylinder on a manual? How big is it? Any manual owners here?

    OK, I understand what you are talking about. The small labyrinth that allows the vapor vented from the crank case at high rpm to slow, cool and drain any liquid back into the engine (still just as often sent to the air-box to be burned in the intake).
    Track bikes would fit catch-cans back when they removed the air-box (carb'd days). I don't think I've seen an OEM "catch-can" (removable for emptying contents).

    You are right. The manufacturers that I see use them have them all rigged so they drain back to the crankcase so you don't have to drain it yourself. The camaro has a separate one, but even it has a drain back to the crankcase. If we were to make like the manufacturers that would not be easy, as we would have to somehow get them to drain back to the crankcase. Thats why the aftermarket ones are just in line and you dump them yourself. Technically I think its better as the crap does not go to the engine, but it means you have to service it. I believe that's why manufacturers don't add the kind we see in the aftermarket. The customer is not going to drain it.....

    I experimented with plastic nylon lines. They are very light and OEM like, and you can put easy connections in. If you watch my vid Post 256 you will see them. I love them. Light, durable, and they look like they came from the factory. A lot of OEM's are using that type of line now.
