Disa fail . Repair question.

OK so my disa failed. And since I'm short on cash, going to simply take out the flap and pin. Now my question is can I use some rtv I have from my vcg to create a new gasket? I know I should replace it but I am a college student, on my own, strapped for cash. I'm not looking at this as a permanent solution but just until I can afford it.

Can I use rtv to make a gasket to seal the disa valave to prevent air leaks?

search for MJlavelle on here. He has the gaskets for $2.50 shipped. I just did mine and it worked really well. Pain to scrape out the old one but follow the GAS instructions and you'll be good to go.

Yeah get the oring instead of trying to make your own gasket with RTV silicone. It'll be more "fail safe" with the oring

Yes, you can use a little RTV, but it will be harder to get it out to repair it. Since your gasket is not bad, you probably dont need it.


You can buy a repair kit for $50-$85 to repair the flap.

Get some plastic epoxy, $7 at AZ, and fill the void where the parts are worn on your DISA. I've got about 7,000 miles on mine since doing this. Just make sure you get it aligned correctly while the epoxy sets up. I believe that vacuum holds the flap closed, and it's spring loaded to open. The solenoid releases the vacuum to allow it to open at about 3,700 rpm (or so, don't hold me to this). So when you put it together with the epoxy, it should be in the open position. See this thread for what I went through - http://forum.e46fanatics.com/showthr...he+dorman+disa

Yeah, but does it hold vacuum when you twist the flap and cover the hole?

Take the flap off, mix the epoxy (get some with a 15 minute cure time) and put a small amount in the socket of the flap. Reassemble and put the flap in the open position and wait until it sets. You probably want to wait overnight before you start the car. It's pretty simple, once you get everything apart. There's a thread on here that explains how to take it apart. You'll have to search for it. There's a plastic cover over the crank arm. Once you get the cover off, there's a retaining washer that you take off. Needle nose pliers will do the trick. GL.

Disa fail . Repair question.

If there's play in the flap the plastic hub is on its way out. I would fix with the GAS kit personally and you will be good for years without worry.
