    Good video but if you've come this far and still want to leave the rod in there for emissions reasons you should atleast cut out the divider that is cast into the housing with a sawzal. After those are out you can dremel the inside of the housings flat and even knife-edge the rod for maximum airflow. This will give you the most benefit and retain your emissions systems.

    Good video. BTW the screws strip because they are crimped or staked on the ends, they are not a softer material just regular plated steel. So no amount of soaking or heat will help you.

    Is it possible to remove the OEM TGVs and just jump the sensors? Kinda like jumping the PCV sensors while doing an AOS install
    Or maybe just have the motors sit somewhere else in the engine bay with aftermarket TGVs in their place?

    If anything screws potentially coming loose in the TGV and going into the motor is reason enough to leave them out. I remember on a Nissan car with QR25DE motor I owned screws on a similar butterfly intake emissions BS coming loose and destroying motors was a common problem.

      Sneaky Foz WRONG ! All factory butterfly screws are tapered on the opposite side . Nearly impossible for them to screw themselfs out . You don't have to go thru the trouble of drilling them out but just use a Dremel and quickly grind the threaded end off and the screw will easily screw out .

  • @dezertdime1072
    @dezertdime1072 4 ปีที่แล้ว +1

    he probably put the screws back in because when the blades are in the warmed up position and the holes are not inline with the air flow it'll cause a whistling sound that could potentially be annoying if you could hear it because air is flowing past not through the hole and then you'd have to tear everything back apart to replace those screws

  • @InobuZ
    @InobuZ 4 ปีที่แล้ว +3

    Actually you have to look at the holes as voids in the path of flow. Picture the water going down the river. The voids in the path causes the water to swirl. That swirl creates a cushion and ripple in air flow. The bolt will cause the air to deflect outward creating a vortex which can be beneficial.
    The effects will be see in the higher RPM's at top end speeds.

    BTW, regarding screw holes, and the little bit of side draft they might pick up when open position. Here’s my thought... super super brake clean, dap of Jb weld, file and sand smooth.
    Only concern is whatever flows thru those TGVs goes straight in to the heads. Yikes.
    So if the Jb weld didn’t hold, we just killed a motor for .003 horsepower.

    Unknown knowledge: How long do those flaps stay closed? The answer is as soon as you start your car, the plates remain closed and will stay closed for 200 years. As soon as your foot touches the pedal and the ECU senses a TPS reading of 1, they flip open and stay open until you turn off the car. The myth with these is that they are closed "until the car is warm" and that's not true. The real power adder comes when boring them out and tuning, however this is an interesting $0 way to do some work on the weekend for a smattering of power.

    Most noticeable on na engines turbulent air creates better air fuel mixtures and more power rather than having unburnt gas getting into the exhaust. When port and polishing they get better results when they use rough grits or even create dimples on the intake cylinder head. You left the rod in there so you still get some turbulence.

    You DO NOT have to drill the screw out . It's much easier to just grind the threaded end off and the screw will screw right out . Use a dremel or drill with a grinding stone . Obviously leave the screws out once removed . All factory butterfly screws are tapered at the end making them nearly impossible to screw themselfs out and destroying a motor . The tapered end is why you'll strip them before breaking them loose . All said , nice video .

      The problem you’d most likely run into with removal of the shaft is an engine code. Correct me if I’m wrong, but one of the connectors on either side power a solenoid that rotates the shaft, and one powers a position sensor for the shaft. Long story short… no rod = no position sensor input = engine code.

Taking the manifold off wasn’t that difficult I left the TGVs connected to the manifold so it’s easier to take out.

    What are the symptoms of these going wrong? I get intermittent CELs, a bit of power loss at higher RPM, plus that "limp mode" occasionally, AND for about the last 6 months since the CEL first started coming on, my 05 STI makes a low whistle that wasn't there before. Could one of these be stuck partially closed? I'm told this is a known Subaru issue.

    Have a question just finished a complete ej22 rebuild and has been pretty successful. I used alot of the information from this channel which I am super thankful for! The question I have is. I noticed oil around the valve cover gaskets, so I got felpro grommets and gaskets. The oil lessened but can now see dampness around the bolt heads. Over night I get about an inch diameter sized oil spot in the garage. I turned the bolts about a 8th of a turn when the engine was hot in torque sequence and that seemed to stop the oil a bit more. I figured since the aluminum is hot the bolt will go in a bit more and when cooling off will pull it tighter. The oil is a little less now. Any tips? Should I check the torque value or maybe turn them in more? Should I back them out and put rtv around the bolt heads? Thanks alot!

    • @SubaruONLY
      @SubaruONLY  6 ปีที่แล้ว +3

      Hi. These valve cover seals can be so freaking frustrating!!! I know and I have been there! Factory gaskets are best but Felpro one usually work too. Ok, assuming inside valve cover channel is clean, bolts all installed in correct order and torque, and head surface is clean, It should seal. Sometimes you do need to add a little RTV at corners with sharp angles, like around the front cam snouts and over those little half moon plugs in the heads. Of course, many (including myself) have resorted to just RTVing the $hi! out of it cause that mofo just WILL NOT seal. It’ll be a pain in the ass later too but at least it will seal and be done. Hope this helps. Realize it really isn’t much advice actually. Cheers. 🤙🤙

This is the first time I've ever seen it done where you leave the rod in. But if your question is what I originally asked just get the TGV CEL code tuned off and you're good to go. Sure you probably figured it out by now 10 months later lol hopefully you made out okay and everything worked out for you. -L

      Yes, sorry, that’s exactly correct. I realize I didn’t make that very clear. Keeping the rod and sensor prevents the check engine light from coming on due to the sensor being missing, but then having the little plates gone will likely create an different check engine light (or will at least require a tune to run smoothly, haven’t verified if it actually trips the check engine for the tune being off).

      Going by memory…Just need to disconnect the fuel, vapor recovery, vacuum lines, and throttle cables, etc. Then, pull the air intake components, but leave the throttle body on. Disconnect all the wiring plugs. Then remove the long bolts that hold the IM down, leaving the bolts in that connect to the TGVs. Think that’s about it.

Off road I would remove the thing altogether and use a 1/2 phenolic spacer ported to the heads and UIM. The tumble should help with low rpm mixture burn and therefore torque.
