WINDSHIELD WASHER RESEVOIR - VACUUM
1992 Nissan 300ZX • 100,000 miles
The windshiel washer resevoir inthe rear deck lid, drivers side of my 92 300 zx 2 door / Non turbo has been " hissing" for about 2 weeks. So i filled it with fluid and the system still does not spit wash to my windshield, though the light on the dash went out. PROBLEM - after running the car for 2 minutes i heard a KNOCK, like someone knocking bowling balls together (just one knock) and i immediately shut off my engine. Under the left side of the intake manifold ( right where the are is brought into the top of the cylinders ) in the engine compartment i now see blue water drops coming from what seems to be outta nowhere ? Any ideas before i attempt to start the car again ? The engine had been swapped out about 2 years ago and i think a vacuum has sucked the wash fluid to the wrong spot. Thanks -Sean

Once the wash fluid got to the manifold it was a noticable loud knock that was definately out of synch from the RPM of the engine as i shut it off.
I cannot offer you any other suggestions. i can't hear the noise so i can't really tell you what it is...
I guess ill just have to try and see tomorrow. in my novice guess it almost sounded like the timing jumped when the water caused a cumbustion glitch which then caused the piston to maybe hit a valve....?? guess, which i hope is wrong.
I really don't know if you have everheard of water injection, it's beenarond then goes then comes back but start the damn car up and if it still knocks then take it to a pro who can give you a professional opinion. I really dont' think there is much damage there at all....i can offer no further assitance and glad you found the mistake.
Ok ill do that tomorrow and i thank you for your help, you have been an allstar. Should i cap that port/nipple that im pointing to in the picture. There is no hose or purpose that i know of. That will be my last question. - Sean
