    I just bought a 1986 300 ZX turbo with 120K that has always been adult owned. Everything works, including the a/c/ . I have a few questions, if anyone can help...
    1. What viscosity oil, and regular or synthetic?
    2. The transmission shifts nicely, but the fluid looks dirty. SHould I change it or leave it alone?
    3. ANy way to check the timing belt? I don't know when it has been replaced.
    ANy other tips will be appreciated. Thanks Tim
  • Is there a glue or a kit to fix the dash at the defrost vents on the 300 zx. The past 3 I have had have this problem

    I have a 90 300zx non turbo, i have been experiencing a noise like a loose lifter up top on the passenger side of the block. also i have no idea why but i have been dumping fuel bad, my oil pan has a huge fuel content to it. i have just gotten it reasently and im not real fullmilure with the fuctions of this car. if anyony can lend any pointers of were to start it would be greatly appreiated, and i thank you in advance.
  • Probably a bad injector and possibly a head long have you had it and in what state did you buy it....either get rid of it..or order a jdm engine. As much as a love these cars...the injectors go if they haven't been replaced in the vicinity of 130k and the head gaskets seem to blow easily. I have had 6z's now...and have had ONE on the road...i cut the rest up for parts b/c they had so many issues. Let me know if you need parts....i'm scrapping on this week that's stripped except for the engine.

    ive only had it for about a mounth. it was my friends car that i was helping him build. it just had a new RS crate engine put in, that was ready to go pretty much out the crate. when the engine place put it in they said it was normal but it doesnt sound right. he was tired of it and let me get it. dont think head gasket, not over heating now that i fixed a hose, and no water in my oil.

    im not sure about my injectors, never checked them. i was thinking along the line of fuel pump or fuel pressure regulator.

    if i were to have to order the engine about how much do they run, and what website would i need to go to for a good one.
  • I don't know if I'm just getting to old or loosing my mind or both but I don't know how in the world me got to scrapping an engine (or car) because it has a fuel leak. I'm not a car mechanic, but I have been a construction equipment mech for more than 40 yrs and during this time, I can count on one hand (maybe 1 1/2) that I've had to bring a car to another mech. If this car had a carburater, I would say have it rebuilt and thats it. BUT, its fuel injected, which I know almost nothing about but I do know this. There's very few places that can cause your crankcase to fill with fuel. If this was my car, I would buy the manual and just keep pulling components off until I found the one thats leaking, replace it and I'm done!!!! I bought my car ('86 n-t) a few months ago and the engine ran so poorly that the guy took $550.00 for the car. I started "sniffing" around and found that all of the injector connections were corroded. I spent less than $100.00 on the car, cleaned and re-insulated all the connections and now, you have to turn the radio down to hear if the engine is running. AND, if I want to have some fun, I can spin the wheels and wake up the whole neighborhood
    Get some wrenches, get some advice, and fix the dam thing!!!!
  • 1990 300zx non-turbo Coupe ........ Old starter went bad so I replaced it. Now the car will not start. Can someone please help me out.

  • bad prob moved the grounds and wires enough to disrupt them....i had LOADS of issues with just moving wires around and making bad connections...try cleaning them up if it ran prior to the starter failing.
  • when sitting in nuetral turbo gauge at -7...when given a quick jab on throttle gauge quickly rises to zero, but not above....does this seem is not ready for road yet.....does it have to be on road to start building positive pressure
  • ambient display reads -56 and never changes compressor will not turn on....any suggestions if it is the sensor where exactly is it
  • Hey Buc, this is Dave (engdocpro). I read that you've scrapped out some Zs. I've got an '86 n-t 2+2 and I'm looking for some parts on the cheep. #1 I need the two struts that hold the hood up. #2, I need 3 hub covers for the standard alloy wheels #3 I need the bottom leather and vinyl seat cover for the drivers side (has to be tan) and OEM #4, I need an Injector cooler relay, the one thats located under the side panel by the left rear seat #5, I need a r/s headlight lift motor (got to be working one) #6, I need the two little knobs that you push up to release the handle on "T" top. Also, any ideas on where to get OEM headliner material (tan). You can reach me at: Thanks
  • I own a 1986 turbo,I don't think you have a problem.At an idle the guage shows a vacuum of -7 as you hit the acellerater the throttle plate opens thus showing less vac between the plate and the intake,what you should find is that when driving this condition will be noticed as turbo spools and transitions from vac to boost.hope this helps.
  • your ? 3 the timeing belt is behined your fan protected by a metal case over 2 pullies you cen check the teeth on it but if it comes off line it up with the 1ST spark plug wire in the distributer cap.
  • i have a 89 nissan 300zx i replaced the water pump and timeing belt fixed timeing but it wont start. any thoughts?
  • i have some extra tubes that came with my swap that are connected to some sensors of some sort don`t know where they go if ANYONE HAS ANY INFORMATION please help!!!!!
  • Thats not really true, if the drive shaft is not true (out of balance) it will still cause the vibe because it is still spinning. shaft doesn't have to be under a load. best thing to do is to jack up the rear install jack stand under the chassis remove the rear wheel put lugs back on spindle and tighten. Put the car into drive and accelerate above 40 mph. if vibe still exist then drop drive shaft and get yourself a one piece drive shaft. you can take your old shaft to your local machine shop and they will build you one using your old yokes. approximate shop time is 2 hrs plus the price of the tube. Total time it takes me to remove from vehicle and reinstall is 1 hr.
  • I have recently swapped the engine in my 88 300zx and have been unable to start the car. The security light on the instrument panel flashes continually after the battery is connected, even after the door locks have been cycled (the recommended reset for the system). I know that the security system shuts off the fuel supply to the injectors and that seems to be where the problem is, since I have established that I have spark and all else appears normal. My question is: would having the rear hatch off for paint be the cause of the security system not resetting and therefore shutting down the fuel supply?
  • I have a 1991 300ZX turbo. Occassionally when I turn the key the dash lights up but nothing else happens. If I turn the key a few times it eventually turns over with no problem. Sometimes it goes months without this happening and then it starts happening daily. I put in a new starter, which seemed to work but didn't. I even tried a new key as the old one was worn down. Again it seemed to work but didn't. Any thoughts would be appreciated. Thanks

    Sorry I can't help you with your problem, but as an owner of a '88 300ZX, non-turbo, I was wondering what prompted you to swap the engine. How many miles did the original engine have?
  • With 245,000 miles the crankshaft broke. A friend had an engine out of an 86 with 55,000 on it (pulled from his attempt to mate 300ZX and 16 point buck), so after swapping out a few external pieces (pulleys etc) we stuffed it in. Now all I need to do is get that pesky thing to run!!!
  • hpmctorquehpmctorque Posts: 4,600
    Well, with 245,000 miles your 300ZX didn't owe you anything, although I've never heard of a crankshaft actually breaking.

    Good luck with getting your Z back on the road.

    I have a 1994 300zx non turbo. Not toooo long ago I broke my timing belt (yeah I know). Anyway I have replaced all necessary parts and tried to start, no go. All my warning lights are on and even with the car unlocked the "security" light stays flashing. on the car will crank, but nothing happens. According to the manual I needed to disconnect the battery so I wouldn't get shocked while removing starter. I am thinking there is an issue with the theft alarm. The car is in great shape, but I don't think I am getting fuel to the injectors. I hear the fuel pump. I also hear a slight squeak that runs as pump starts might be nothing, but??. Does anyone know why all my lights are staying on and why the car is not turning over?

  • chuck have you tried to reset the alarm with the doors and hood all closed and then lock and unlock the door with the key ? also you may half to reset the codes in the computor or you can try putting it in test mode to see what errors it gives you
  • I would start by looking into the front braking system,you are probabally getting pulsation from front brake rotors.If you replace rotors also replace pads.also insure that you don't have a brake caliper that is stuck as this would spoil new pads and rotors.from what you are saying this is a very good possibility due to the fact that the wheel shakes while driving down the road as well as when you apply the brakes.

    Hey Justin,
    Yes I have tried what you have suggested except testing the computer. I was told that if you turn car (not start) and disconnect the neg terminal turn car off and reconnect it will reset alarm. didn't work. Called Nissan dealer and he suggested that I touch pos terminal to neg (pos off battery that will reset alarm. I will try the computer idea. are u talking about the ECU? Is it under the floor board on passenger side? Thanks for your reply and help I will let you know what happens.
  • yes it is located under the passenger side kick panel or side panel under the dash by the floor. hope it helps.

    One thing to look for is the secondary ground on the negative cable behind the battery. If this is not attached it can cause quite a few weird problems,including dying as you come to a stop, because it starts to draw current away from the ECM. Hope this helps.
