liamgdr Posted November 26, 2013 Share Posted November 26, 2013 Hi guys im new to the forum, I just bought a zed on saturday, until yesterday it was running great, not a problem. However yesterday when I pulled onto my drive I noticed a fast tick coming from the engine bay, at first it sounded like it was something to do with the a/c because you can hear it better in the cabin than outside the car, but I had a look again this morning and it seems to be coming from the top of the engine. I took a pic of where it was coming from and also got a video. I've had a look at the oil and its the right level and is a dark syrup looking colour, basically like its from the bottle. Any ideas what it could be, I just want to get out in the car but don't want to do any damage. Cheers, Liam. Quote Link to comment Share on other sites More sharing options...

Dave-350 Posted November 26, 2013 Share Posted November 26, 2013 Does it speed up with the Revs? Noisy injector or tappets I can only guess. Quote Link to comment Share on other sites More sharing options...
peteman35 Posted November 26, 2013 Share Posted November 26, 2013 (edited) Welcome along! Could be the fuel dampners there are 2 behind the plenum(intake) will look like brass mushrooms. If yiu start the car put a screw driver on it then put your ear to the screw driver. You will hear it if it's that Edited November 26, 2013 by peteman35 1 Quote Link to comment Share on other sites More sharing options...

liamgdr Posted November 26, 2013 Author Share Posted November 26, 2013 Yeh it speeds up, but its hard to hear at higher revs over the exhaust, its quite quiet in the cabin. Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted November 26, 2013 Share Posted November 26, 2013 (edited) Hard to tell from the video Liam but possibly fuel regulator/damper. Alex. Edited November 26, 2013 by ZMANALEX Quote Link to comment Share on other sites More sharing options...

Richf Posted November 26, 2013 Share Posted November 26, 2013 Funnily enough my recently bought zed is making unpleasant noises , checking you tube there are dozen of vids of fuel dampner and dual mass flywheel rattles , it seems widely regarded as normal Quote Link to comment Share on other sites More sharing options...
liamgdr Posted November 26, 2013 Author Share Posted November 26, 2013 Just had a look, is there two fuel dampners? I found something that looked like a brass mushroom directly under the air intake to the engine and an other to the left of the engine ( a lot more visible ). Both made fast ticks when i listened to them through a screwdriver, but the sound does appear to be coming from underneath the air intake. Is this a common problem? Cheers.

Tricky-Ricky Posted November 26, 2013 Share Posted November 26, 2013 (edited) Apart from the injector and general lifter noise, it sounds like a lazy lifter to me, the frequency is half engine speed, Edit, LOL! forgot they are non hydraulic followers, so yes could well be wear/too large clearance.

Cheers. sorry just re-read peteman35's reply, as both fuel dampners make the same sound im guessing they both cant be faulty? Looks like 'Im going to have to get it to a garage at weekend. Any decent places near stockport/manchester. Quote Link to comment Share on other sites More sharing options...

ZMANALEX Posted November 26, 2013 Share Posted November 26, 2013 Also do not rule out worn camshaft lobe. Alex. Quote Link to comment Share on other sites More sharing options...
liamgdr Posted November 27, 2013 Author Share Posted November 27, 2013 Had a listen through a stethoscope today, the fuel dampener on the left makes a high pitch quiet tick the other one makes a lower frequency knocking, the same sound I can hear when in the cabin, so I appear to have found the fault . The only problem I have now is fitting the dampener, is it easy? Looks like it should be, wheres the best place on the internet for nissan parts? Cheers, Liam.

ZMANALEX Posted November 27, 2013 Share Posted November 27, 2013 Liam, I have plenty preowned low mileage fuel dampers in stock. Just drop me a PM if I can help you further. Alex. Quote Link to comment Share on other sites More sharing options...
liamgdr Posted December 12, 2013 Author Share Posted December 12, 2013 Fitted the new fuel damper, unfortunately the ticking is still there. Rechecked the oil, it looks good, but when I rub it on a metal surface with my finger I can feel very small pieces of grit, too small to see. The oil was only changed it the last 2000 miles, so isn't old. I'm going to replace the oil this weekend, I'm going to get either motul or Fuchs, but is it worth running some cheap supermarket oil through the engine for 30-40 miles first to remove the crap before I put the good oil in? Cheers, Liam. Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted December 12, 2013 Share Posted December 12, 2013 Liam, May be a plan to pull the rocker covers and check the valve clearances and also for worn cam shaft lobes. Alex. Quote Link to comment Share on other sites More sharing options...
liamgdr Posted December 15, 2013 Author Share Posted December 15, 2013 I think that will be the plan for next weekend, can the clearances be adjusted? However I had the car looked at today by a mechanic and he wasn't bothered by the noise, said it was pretty normal cam chain noise, so im not sure where to take it from here.

liamgdr Posted December 15, 2013 Author Share Posted December 15, 2013 If this is just a general noise from the cam chain, lifters, other moving parts etc, could swapping the oil for something thicker make the engine quieter? From what I have read 5w30 is best for cold starts, but I only use my car on weekends and wouldn't mind spending time warming the engine up.

You shouldn't be putting anything else other that 5w30 in it! Quote Link to comment Share on other sites More sharing options...
