andlid Posted June 21, 2010 Share Posted June 21, 2010 fuel feed hose with damper... Cheers for those mate, I've already looked through the workshop manual almost front to back looking for clues. That section is handy, but is really quite vague as to what they mean by each sound...a 'tap' may be a 'knock' to other people!! Considering there was (somewhere) a TSB about the fuel dampers making a knocking sound, and mine is pulsing...I think I may have found the cause?? I can't remember where I saw the TSB though!! http://www.350z-tech.com/zwiki/Category:TSB Quote Link to comment Share on other sites More sharing options...

Reading this thread linky, he does mention there was a TSB on it. I'll keep searching!! Did you manage find anything by any chance... i have the same noise Flywheel!! These dual mass flys have a habit of developing a bit of movement which makes a knocking noise at idle. Allegedly they have the same on transit vans, and most mechanics modify them to work with a single plate fly when they need replacing. Nothing to worry about, just change it when the noise gets unbearable or it starts to affect the drive. Mine's getting on for 45k, so although it doesn't need it yet I'll soon be popping in a new fly and clutch. I'll make sure I get a single plate lightweight flywheel though, these dual mass ones are rubbish!! Quote Link to comment Share on other sites More sharing options...

Androo Posted October 11, 2010 Share Posted October 11, 2010 Typically with the Vauxhalls - the 1.6 & 1.8 units have had this problem son their 98-06 cars - and the remedy (other than spending £1100 on clutch/flywheel combo).... single flywheel!

matteovds Posted yesterday at 22:33 Share Posted yesterday at 22:33 On 17/06/2010 at 19:30, terribleone said: My Zed has started making a strange knocking/tapping sound coming from the engine...I'm getting it looked at on Monday, but thought I'd post up on here to see what ideas people might come back with for discussion with my mechanic. I've got a video of the sound here which might help: I'll run through when the noise happens; Start engine up cold, no tapping at all...revving at idle sounds smooth and releasing the clutch just gives the usual thrust bearing grumble which we all have! Driving the car is absolutely fine, no odd noises from the engine and still drives fine and pulls well too (although I have not been pushing it hard since hearing this noise). Stopping the car while still fairly cool doesn't seem to make any sounds either. Giving the car a good 25 minute drive and then parking up you then notice a slight knocking sound, getting out of the car and popping the hood the sound becomes more apparent. Revving the car, the knocking raises with the revs...but only to about 2.5krpm where it becomes quite unnoticeable. Also, while idle the exhaust occasionaly make small pops and splutters although nothing dramatic. So the noise only occurs when the engine is nice and warm, and when at idle or very low revs. It also appears to be coming from the top of the engine to the rear of the intake manifold more than anywhere else. The car has always been well serviced, never thrashed in my ownership and is due an oil change in a couple of months or about another 4000 miles. I'd appreciate any opinions, advice or suggested further tests to pinpoint the source of this sound. I don't want to be paying big bucks to get the whole engine stripped down only to find it was something like a sticky lifter!! I'm quite a bit upset at the thought of my car having something drastically wrong with it after 6 months!! As always, any help would be greatly appreciated!! Hey, i was wondering if you could make the video public so i can compare it. I think i might have this exact problem. Quote Link to comment Share on other sites More sharing options...
