I recently purchased a 90' 300zx coupe and have had no problems until recently when i have noticed a gurgling noise from within the drivers door hinge/front quarter panel. It seems to be coming from a hose (just visible) and sounds similar to the noise made when sucking the last bit of milk shake through a straw. I have checked the levels of everything liquid and have found everything to be full, which makes me think it may be the air-con which isn't working as well as it should (not cold). Does anyone know what this hose might be connected to? Tom
The pipe you saw was the Air injection valve if i am correct. There should be no water present. You should have it looked at! Remove the wheel, the plastic mud-guards, and there it will be infront of you. See ya and good luck!
thanks guys Thanks for that guys, it's sounds like the aiv's the problem. I'll get it checked out. thanks for your input, tom.
