Yes the bracket that bolts to the engine and the tensioner are a matched set. You can swap them out as long as you have both. I have spares of both types if you need them.

sure seems like a pinhole in the condenser. Not 'rare' really for any car I guess. You could try some UV dye in a charging attempt I guess to confirm it.

Doesn't work. The ECU looks for a corresponding change in sensor inputs (probably a drop in MAF voltage) to verify the EGR is functioning. You can't just hookup a solenoid - you need a solenoid that drives an EGR valve through a proportioning valve and that creates a vacuum leak of the proper size. You *can* pull atmospheric air from the IAC hose into the EGR pipe and avoid doing the drilling of the exhaust port on the head but it's not completely ideal as it will result in a minor positive fuel trim condition when the ECU has to add fuel for the additional oxygen being introduced but not metered by the MAF (true EGR is inert so has no effect on AFR).

that's one hell of an amazing first car for your kid to show off at school! I love Zero, more pictures of that one please!
