    Instead of bypassing the HX buried below the manifold didn't someone install another style of HX close to the fender?

    Yes, the 2 banjo bolts are feed and return of transaxle oil. The coolant goes through the 2 boots/reducers on each end going through the Heat Exchanger. I would have started by giving a 1/4 turn extra to the clamps that hold the boots to the H/E. They should be accessible with a long extended ratchet from the top (threading in between the intake plenum pipes going down to the head)....
    What you see leaking from the banjo bolt may be coming from the boot high on the HE and it catches the banjo and leaks from there.
    If you actually have coolant coming off from the banjo, your transaxle is toasted!

    Good luck...

    You wore 110% right. I was able to see where was coming from. I worked the scope camera around the HE and notes coolant coming from the end of the boot facing the engine. Ur suggestion is to replace the boot? Or just tighten the clamp?

    Try tightening the clamp first, sometimes that's all it takes... Easy, cheap, rewarding... :)

    the track and the seat are one unit. you remove 4 bolts and the track/seat are free to go

    Is it possible to remove the heat exchanger just removing the pump assembly? I need to replace the botts on the heat exchanger. Thanks.

    It is, that's how most people do it. I removed my intake so I could replace my runner gaskets

    I saw the leak coming from the boot close to the engine. Ones i tide the 2 clamps it started to leak like crazy only with 5 pounds od pressure. Did i over tighten? Did i bend the exchanger? New is 900$. Any way i can still use it ? Or should i just change the boot? Whats your advice? Car only has 20k miles, but is still 17 yers old. .
