  1. It was the BCDD that caused that annoying sound, blocked it off and then the sound was gone. So I believe those small cracks in the diaphragm is the reason for this. Is it possible to buy the diaphragm anywhere? Have not been able to source it so far...

  2. So, after some more checking and listening the source to my trouble is the throttle body or the bcdd. According to FSM the bcdd shall not be adjusted, it should be replaced if it fails. Don't find it easily available so guess I will try to disassemble and clean it. 

     

  3. The rpm in the video was a bit high, usually the idle is at 8-900 rpm. I'll try to record a new video and see if I can capture the sound a bit better.

     

    Maybe chiming is not the correct word to use but its a bit hard to describe the sound... Coming somewhere from the intake but really difficult to locate so will try with some kind of stethoscope.

  4. Got this strange chiming noise coming from the intake manifold but it only appears after the engine has reached operating temperature. Its only present at idle or when I get off the throttle, once I give a little throttle the noise disappears. Adjusting the idle screw up or down does not make any difference. It does not affect the performance as far as I can tell. So I been thinking that it is vacuum related but have been struggeling with this now for a while without being able to figure ot out. Have done the egr delete, blocked off all parts of itand blocked off the line going to the throttle chamber. 

    I've attached a video, the annoying sound is easy to hear from approx. 20 sec into the video (never mind the rough idle at the end. Got some moisture after washing the car but that does not have anything to do with that sound as it was there before the car was washed.)

  5. Have thought about that solution and guess that is the only option I have. According to the FSM, shims can be placed between the body and the hinge to align the hatch but it does not mention any other way of adjusting the hatch..?

    Not many Harbor freight in Norway so guess I will have to make my own..

  6. Thanks for pictures and replies. The warmer plate looks familiar, believe it has been laying around on my workbench for months ;)

    When it is removed, how much longer is the fast idle running?

    Does anyone have the dimensions for the plugs needed to remove this? I would like to keep the heater so just want to get rid of the t-joint where the lower radiator hose connects.

  7. I stripped my car down three years ago and I have finally started to put it together:D I removed the EGR from the intake manifold and possibly some other things I cant remember and now I have two hoses I don't figure out where to connect. I've tried to look at pictures of different engine bays but i can't figure out exactly where they should go, and there is no obvious connection point for either one so thinking that I, in a weak moment, have removed something more without putting it back....

    The hose connected to the hard line running to the other side of the engine, where should it go? Since the rubber hose is rather short there is not a lot of options...

    And the longer hose running from the thermostat housing

    From what I have read it seems like the hoses are for heating of the throttle chamber/intake manifold and that they might be blocked off if the car is not running in cold environment. Since I live in Norway it could be sub zero temperatures even though it wont be driven during winter so would like to have them...

  8. Thank you guys.

    I got a qoute from Datsunpartsllc for the door window outerseal with molding, 150$ each side! Have anyone tried this one? Is it the same as the one Black dragon sells for 50$, or is it a different brand?
