I've been busy tracking down little leaks in my car. I started at the turbo and have worked my way following the same path that the charged air would follow. So far I've been pretty lucky in stopping the leaks completely or got them down to a very small one (damn BOV!)

Anyway the next one I've found is around my fuel rail. I've lightly sprayed soapy water but it won't bubble. I can hear it, and I can feel it with my hand. It does not seem to be coming from the injectors but this 12mm bolt. The bold holds the fuel rail to the lim.

I don't have a lim laying around but it seems unlikely to me that this bolt actually goes deep enough in the lim that it connects to pressurized air.

Here is the pic. Is it possible to leak from that bolt?

Nope. It's probably coming from the front primary injector right behind the bolt.

 

Definitly not the bolt, but there is a nipple at the inside base of the LIM, under the rails, that is easy to miss. Im not 100% sure if its just a pass through or not (been 10 years since Ive owned a stock FD), but its worth looking into.

 

The nipple is leaking. Once I cap that I will check further. Too bad mcmaster-carr won't ship to Canada.
