WINDSHIELD WASHER RESEVOIR - VACUUM
1992 Nissan 300ZX • 100,000 miles
You might. but the knock could be form anything really
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.
So i tooled around today and followed the rear resevior hose from the right wheel well up and over and around and someone hooked it up direct to the #14 AIV Control selonoid to balance tube which is attached to part # 5 fuel damper to balance tube. RETARDS !! So the hose was basically pushing washer fluid direct into the air manifold (like NOS but wash fluid instead) - I think about 2 ounces made it into the chamber all-in-all. I then hooked the washer fluid hose up to its rightfull location and now it works fine and sprays the windshield as desired. I wonder what the colateral damage may be ? Ill wait till tomorrow to try and start the car. Should i expect anything or just prepare for the worst? Should i spray any carb cleaner or booster in there to counter the water / fluid? I left the throttle propped open though i dont think it wil help other than mentally.
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
