Hi all I have an 05 DE and also am now worrying about a ticking, first noticed it when at low revs reverberating off walls etc at the side of the road at the back end of the year, though not noticeable with the roof up/windows closed. Now waking the Z up for 2019 and spent some time with a bit of hose pipe to my eartrying to locate it. Most noticeable at the back of the engine toward the passenger side, particularly so on the fuel rail. I therefore replaced the back fuel damper but has not made any difference :-/ Could not really hear it from the front (with the hose pipe) so don't think it is the time timing chain. The car has only done 37k miles with annual oil changes, albeit as a weekend car when driven, it is generally "well exercised"
I have some wynns engine flush and mobil 1 5w30 to try, but not really holding my breath. There seems to be lots of posts and clips of similar ticking, but I can't ever seem to see anyone reaching a solution, cause or cure. Surely there must be a zed expert who has followed this through to final conclusion/fix.
I am actually starting to wonder if it is just normal noise for this motor. Has any one got any sound clips of a 350z de running hood up new, or knows that it is 100% OK. I keep reading about noisy hydraulic lifts etc but then read the z doesnt have lifters...
Can injectors make a tick?
ThreeFiddyZ I look forward to your next update - I will post the outcome of my engine flush and new oil! Thereafter wondering what to try next.
Cheers Rich
