Coolant leak rear of engine

[seagull369]

I've got a coolant leak coming from the rear of the engine on the driver side. The EGR tube on that side gets wet and the drips eventually land on/near the manifold flange on the manifold on that side. Only happens when system is fully hot (or when I fully pressure test it).

Would anyone know of some possible causes on where it could be coming from? I don't think it's either heater hose. I took the brake master out to get a better look, but still am having trouble narrowing it down. Am planning on looking at it from underneath with a camera tomorrow.

I pressure tested again today and saw/heard some bubbling coming from a hose under the plenum on driver's side bank (bank 2?). Specifically it's close to cylinder #4. Unless I've got 2 leaks, I guess the coolant is leaking there then running out the back of engine where I saw it dripping.

Pulling the plenum looks like lots of fun. Hopefully I can find a tutorial or 2 on doing it.

To ensure no leaks again in that area, coolant line delete link:

Book mark the Z32wiki for futre reference, Enjoy:)

Thanks for replying. I noticed both those pages in my searches plus 2 good vids on utube regarding the plenum pull (on an NA, anyway. Hopefully the tt's aren't too different there)..
