According to the mechanic that I have working on my air conditioner, some of the wiring in the dash is "bleeding" over to other components and could cause the battery to go down when the vehicle parked for several days. Would anyone know if I have to replace the Harness Assembly that controls the wipers, rear defroster, air conditioner, etc. or if there are portions of it that can be replaced? Also, is there anywhere that I can find replacement wiring that did not come out of another car that has been sitting in a junkyard for several years? Be gentle...I am a new member and haven't owned a Zcar in 26 years. Hornz

I recently acquired a '78 280Z and am in the process of restoring it, everything works well and is in decent shape except for the rear-end. It had a nasty CLUNK when shifting gears and makes a WOOM-WOOM-WOOM noise when you get the speed up to about 30mph and up. Well I checked the differential and sure enough it was shot with about a half turn of play on the input yoke. I found a nice tight used one locally and swapped out the old diff. That cured the CLUNK noise but it still has the WOOM-WOOM noise. I took the rear brakes apart no sign of problems, and I took the rear hubs apart to check the bearings, everything was great and fresh grease didn't stop the noise. I did not…

It was in the 50's today, so I decided to take my new 78 280z 2+2 for a ride, and had some problems. When I start it it idles rough, (sounds like it has a big cam in it. ) but when I rev it , there is a slight stumble at first, then it revs smoothly, and runs pretty good. I drove it for about a half hour,and I stopped at Burger King, went through the drive thru, sat for 10 minutes with it running (idling rough) , and decided to shut it off. Sat for 5 more minutes to eat, and tried to start it back up, and it acted like it was flooded. I tried starting until the battery died. Walked to the Firestone dealer (3/4 mile), they wouldn't help me, so I walked to Sears (another m…

This is unbelievable. Today was an awsome day to fire up any sports car in Chicago. I decided to take my Z for a drive after finally fixing the Toyota brakes (They work great!). I drove it to the local store, but hitched a ride in a tow truck for the journey home. Leaving the parking lot, I was in first gear and had begun to reach for the shifter at about 3.5 thousand rpm. I started to hear a pinging/grinding noise come from the motor which I am not afraid to admit I built myself. As some of you may know this is a fairly fresh motor. Hearing this heart sinking noise, I got on the clutch and she then died on me. I knew whatever that noise was didnt sound good therefore I m…

Hi – I am the original owner of a 240, SE, 1991 fastback. She has 84K miles on her, is misty blue metallic and purrs like a cat. I adore her. She has been good to me and I have been good to her. She has been in a closed garage when not used for 12 years. Three questions: 1. my 15-month-old battery with a 72-month guarantee would not turn her over. I got a jump and brought it back to NTB, where I bought the battery. They did a diagnostic on it and said the battery health was at 80 percent but the charge was 30 percent and that was because I was not driving it enough. My alternator was fine. I drive her 3-4 times a week, but only for 3-6 miles at a time. Are they…

Well, my stepson walked in this evening after being out with the Z all day and announced that he thinks "there's a problem with the car." Well, to make a short story shorter, it seems as if the bolts holding the cover on the diff had loosened and he lost a mess of gear oil. The ring and pinion are now howling on acceleration & deceleration. Crap... I went underneath, re-torqued the cover bolts and was going to add some gear oil to the diff when I dicovered that the fill plug is fairly well seized and the DPO had done a fair job rounding it off at some point in time. More Crap... I'm thinking this R180 now needs a rebuild, based on the whine. Am I being paranoid, or…

So, Looking under the car this weekend, I noticed that there is some play in the main Driveline U joint but it is strange... It's not acting like play in the needle bearings, but side to side as if the wrong c-clips were used, not getting that sung fit that I typically see. Has anyone else experienced this? Also, dropping that shaft is a pain in the butt from the diffy, anyone know of a method that may be a bit easier? You can't hit it from the back with an extension because the rear end is in the way and the angle from the mount is odd and there is not much room for twisting the 12mm nut that is on the diffy end... I really want this thing off to also check the pinon nu…

Hey folks, Got some disturbing sounds coming from my trans tunnel, sounds like a bad U-joint, but evidently, it's not. Only present with the clutch out and accelerating / decelerating or at cruise with a light load, an oscillating / 'revolving' scrape / clank that sounds like something's broken or in the process of breaking. Mechanic says the clutch is good, trans is good, motor is good. I assume he means operationally. Clutch doesn't seem to have a problem, got a little 'grunchiness' going into 2nd and 3rd when cold(worn synchros, no big deal), no vibration at speed. I'm not sure what the heck this is and I've got a 130 mile road trip coming next week, which I can't a…

hello forum. i am new and it looks like you pros have lots of experience with these engines. i just bought a datsun 72s pickup that has a z motor in it with a weber carb. i was told the truck needed a new fuel pump and ran fine untill 2 months ago. i replaced the electric fuel pump on the frame rail and am still experiencing what i feel is fuel starvation issues. the truck starts and idles perfect. since the new fuel pump it also revs great, no hesitation and full exhaust revving. the problem is, as soon as the truck is driving, it starts to bog and tries to die. the engine is running perfect unless the truck is rolling. i can even push the clutch and work the gas…
