Fix to E46 DISA valve that always stays open

[@lazarousjam]

Awesome job man. Thanks for sharing

Great video,i upgraded my disa valve yesterday with a kit from x8r. I left the small flap off accidentally and put the disa valve back on my car..did all the checks on my disa valve before this and all good. The only thing I'm confused about is my disa valve stays open when i start the car and at low revs..the lever works tho at higher revs.

The valve has to stay closed under 4000 RPM or so, and open from 4000 RPM up. What I don't know is how you would be able to see that yours stays open at low revs and, at the same time, see that the lever works; since, the lever only works by opening the valve, and therefore, you would have to have the valve closed before for that to happen. I did get rid of mine because I've done the conversion to M50 IM.

@@aleknive thanks for your reply, it was the small bracket that's attached to the side of the disa valve that I accidentally didn't reattach before fitting the disa valve back on. I was revving the engine and my dad was looking at which direction the level was moving: all the way to the left meant flap is open, all the way to the right shut. Just took my car for a quick drive to see how it was, feels the same as before. I double checked the disa valve today (before attaching it to my intake) for vacuum leeks and it functioned properly,no cracks on the disa valve. No warning lights on dashboard,disa valve sounds ok, only suction noise.

@@dRew-something No worries. As you said, when it moves to the left is opening, and to the right is closing; so, now with the bracket reattached, it does stay closed at idle, right?

@@aleknive it looks like it stays open when I turn ignition and then closes when I accelerate below 4k rpms..seems weird it does that but at least it works. Next job is sills..rust🙈

@@dRew-something that seems like it doesn't create enough vacuum on idle. Might have a little vacuum leak that is overcome when RPMs go a bit higher.
