cob1980 Posted June 13, 2016 Share Posted June 13, 2016 I've not had my 350 all that long and only driven about 600 miles so far, so I'm still quite paranoid of any odd noises. I know I have the axle clicking issue as it does that now and again (even though the previous owner has rotated the axles and re-greased). Anyway I parked it in the garage as normal yesterday and could hear a faint hissing type noise. I've recorded it on my mobile... probably best listened to with headphones. Seems to be coming from around the diff area. It stopped once I switched off the engine. Didn't trying revving the engine or anything and not used it since. Here's the vid... hopefully it works http://vid1323.photobucket.com/albums/u589/cob1980/20160612_195148_zpstvlp2zy5.mp4 Any ideas? Cheers!

ZMANALEX Posted June 13, 2016 Share Posted June 13, 2016 Can't hear it but perhaps fuel pump. Quote Link to comment Share on other sites More sharing options...
Mopedmark Posted June 13, 2016 Share Posted June 13, 2016 It's sounds as if it's a constant hiss, which could be exhaust gasses, and if you look at the video there looks like black soot marks on the body above the far silencer Quote Link to comment Share on other sites More sharing options...
davey_83 Posted June 13, 2016 Share Posted June 13, 2016 I'd say fuel pump as exhaust leak kinda chugs from the exhaust in a pulse as per the firing order. If it is the fuel pump that's a normal sound. I'm only in Sheldon if you fancy coming by to hear another 350z on idle. David Quote Link to comment Share on other sites More sharing options...
cob1980 Posted June 13, 2016 Author Share Posted June 13, 2016 Thanks chaps Yes fuel pump sounds plausible. It's not quite constant, Id say 85%, if you listen carefully it stops for a say a fraction of a second to a second or so.

David Thanks David might take you up on that offer, I'll see if it does the same next time I use it (which is dry weekends only!) Quote Link to comment Share on other sites More sharing options...
cob1980 Posted June 13, 2016 Author Share Posted June 13, 2016 Just to add... i'd probably not noticed the noise but i was looking for a leak. Doing a little search I think I have clutch fluid leak. When I took the car out on Saturday i noticed a dry but oily pool on the floor, light yellow, smelt bad, it was about a foot in from the driver side roughly half way along the door. I'll check the level at the weekend. Quote Link to comment Share on other sites More sharing options...
