Ok...so it's not "truly" the back of the engine, but, there is a severe leak coming from that really hard to reach area underneath the intake manifold on the RH side. It's near the PCV breather/separator.
A friend of mine thought it might be the coolant temp sensor (temp sending unit?). Is that located there?
Has anyone had this happen? Does anyone have a diagram of what's attached to the back of the engine? Even with a mirror, I'm having a hard time seeing where the water is leaking from.
Two other pieces of info: I didn't have to start the car for it to start pouring out. And, it's a 93 Altima.
Any other questions, I'll be happy to answer!
Thanks! (and...I will be happy to be finished working on this car!)
