In my last dive my Aqualung Titan LX Octopus started leaking air when I opened the tank so I used a spare set. After I took to the local repair shop, he opened the regulator and determined that the lever is the problem. There is a gap between the lever and the valve body (connection holes) and this causes a small to medium air leak.

Did anyone had similar problem with their second stage? He said if we changed the lever, this problem will be solved but we couldn't find a replacement part in Turkey. Does anybody know someone that sells this part?

I have been rebuilding my AquaLung Legend Octo which seems similar to your Titan. My lever legs have ~2mm side to side play in relation to the tube. This has not caused a problem with my regulator. I do not believe this would be causing the air leak. My first thought is the orifice needs to be adjusted inward to compensate for seat wear, or the seat needs to be replaced. The lever legs can be reformed easily to minimize the gap.

That doesn't sound right. I'd get a second opinion from a different reg tech.

The Titan LX second is virtually identical to the early Legend second. I am continually amazed at what "techs" will tell customers. There is always play between the lever and the air barrel and there is no seal here. My initial search would look at the o-ring on the shuttle and the seat.
