Clicking sound from turbos area
Faint clicking sound coming from turbo area, 1993 rx7 stock turbo set up with 76,000k and stock port, + race apex seals and mint housing rebuild with 1,663km.
Noticed it first decelerating around 3k rpm then then the more I was boosting (only boosting .5bar to 4k rpm). It started getting more noticeable and the more I boosted and payed attention to it, I noticed it only did it once I got the turbos hot and once they where hot I could notice it when I was slowly climbing revs and could hear it getting louder. Tonight on my way home after boosting a bit my fatt-x turbo timer which has never gone over 1:45 (min:sec) was reading 2:00 and slowly going up a few seconds every block as I slowly drove home. When I got home I got my girlfriend to rev it to 3k rpm and I didn't see any smoke at all. There was no leaking under the engine or smoke either.
Id like to know what you think is causing this clicking noise. Also I put in new gaskets on the manifold and turbo-to-manifold gaskets and turbo-to-downpipe gasket and exhaust gaskets, maybe they wore in and all need to be tightening? I only started going over 0bar when I reached 1,500k also there was some cracking in my turbo hot side divide that connects to the manifold, I have pics in some of my other threads.

I bought the car not running with the intention of putting in a rebuilt engine. So I had Rx7 Specialists in Calgary build it and I put it in. I got the old engine running but exhaust was getting into the coolant system, so wile waiting for the new engine I bagged the hell out of it until it wouldn't start
I had a similar issue with my turbos:

Try using a piece of vacuum tubing to listen (one end to your ear) around the area in question while the engine is running. This should narrow things down quite a bit ... assuming that it's an exhaust leak making that sound.
