Reverse Ticking Noise And Random Engine Crank Noise On Startup?

Had my 03 v35 auto coupe for about a month now. Great car, and a very smooth drive :D

Picked up on noises lately that I wasn't sure about.

First is at cold crank (usually overnight). Sometimes I get a rattle/crank noise when I start. I'm guessing this is an oil pressure problem of some sort? Rare to occur, but always in the morning. Only noticed it twice in the last week.

The other noise is a ticking noise in reverse only? This isn't the infamous axle clicking problem is it? Fairly light noise, only when I engage reverse and turning into a park. Sounds like its coming from the front. It's a similar sound to CV joints failing in fwd cars (but a hell of a lot fainter)!

The third noise has been deemed normal (thank god). The one when you first take off in D and get a funny noise once you reach 20kmph.

I'll have to try and record these noises at the right moment!

The rattle crank noise you are hearing is probably the starter, the spur gear not withdrawing from the ring gear in a timely fashion, hence the noise, mine does it and I'm not concerned.

For the other noise you are hearing I have no , could possibaly be as simple as a l stone caught in your tread, but I would get it checked out to be sure.

That is due to the oil pressure not building up fast enough to tension the timing chain's hydrulic tensioner. Reason why it happens in the morning is because most of the oil drains to the bottom of the engine. It's not an issue I'd be worried about - as long as the sound dis-appears stright away - if the sound is constant you could be using incorrect oil/time for an oil change or could mean an issue with the tensioner.

You might want to check the oil grade - I think the V-Series use 5w-30 oil.

For the ticking noise, maybe is the ball bearing of the wheel cause it, mine got the same problem, and will check it on monday... the garage guys said that 10 out of 8 customers with 350z or 350GT got the same problem. not expensive to fix.

I sometimes get the startup rattle as well on my 03 V35 coupe and could be caused by the VTC sprocket (gear for the Valve Timing).

From what I've read, it doesn't cause any damage to the engine and is mainly a noise issue.

As Iseekool has mentioned, an oil change should help.

if its a single click when reversing...then its the rear axle ...needs to be greased and rotated

otherwise if its a series of clicking noises...my guess would be brakes or wheel bearing

Hay, just got my V35 checked this afternoon, about the rear ticking noise, the mechanic disassembled the rear wheel rotors and check the wheel bearing, he's spotted nothing and i replace my rear brake pads and machined the rotors...

the noise is still there...=.= he said the car is mechanically okay maybe the shape of my 370Z 18'' wheels that i put on produce the sound by stirring up the air...so the (ticking like) sound appears at a slow speed but disappear later? i don't understand it.. so.. nothing solved LOL....

Anyone else got the same problem?

Thought I'd update this. I've worked out that the reverse ticking noise only occurs when you ride the brake in reverse while turning the wheel (ie. Parallel park). Wierd! If I reverse without riding the brake, all is fine (still turning the wheel of course)...

      I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.

      No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.
