I have had some speculation that my second turbo has gone bad but it doesn't have many of the signs. It is screeming a bit but there is absolutely no oil coming from them in the y-pipe or more importantly in the exhaust.

Lets just say that isn't the problem. Where could I get a boost leak just from the second turbo to the motor. the first turbo is spooling fine and is getting 10psi. Right at 4500 RPM I hear what sounds like a loud boost lead but for some reason you can hear it more on the drivers side. I have checked the rubber hose to the CRV valve and also the valve to make sure it wasn't bad. I have also checked and rechecked all the couplings and rubber components from the y-pipe to the intercooler and the one from the intercooler to the elbow. What do you experts out there think?

It could be several things. Do you hear the transition, i.e. the exhaust gets louder? If so, then your CRV may be staying open. It would stay open because it isn't seeing any pressure in its vacuum line. Go here https://www.rx7club.com/forum/showth...threadid=98645 for info on testing all the problems.
