Hi I'm a new owner of an 05 350z, I have 96,000 miles on the clock and the previous owner said he has already done the timing chain. He never had any paperwork to prove he had done the work though and I don't trust him enough just to go by his word. I'd like to know if there is a relatively easy way to tell if the timing chain has been done before I take it to a professional.
Any advice would be much appreciated.
Thanks heaps.

I don't know if there is an easy way to check a new timing chain versus a old timing chain. If he cant provide paperwork, receipts, pictures than I would assume he is bullsh!tting you but dont let it ruin your weekend - the timing chain is pretty solid and can go 200k miles.

Welcome- there is no easy way to check on whether the timing chain on a VQ35DE has been changed or not. My question would be why he'd do it in the first place? Unless the engine was rebuilt for other damage, there's no reason to change out the timing chain. You'd be better off pulling an oil samle and sending it off to Blackstone or Titan Labs and getting a UOA to get some idea about the overall condition of your VQ.

I did read on another forum that the timing chain should be changed between 100,000 and 125,000 miles but if you're confident that I don't need to change it then I'm happy with that.


Thanks for the advice, much appreciated.

Please post your source on where the timing chain needs to be changed between 100-125K miles? There's nothing in any Nissan maintenance documentation on this. Nissan timing chains will generally last the life of an engine if other standard maintenance (like oil/filter changes) are carried out.

Hi, I have a 2007 Nissan 350Z which I dearly love ! (250, 0000 miles ) , but the engine light has turned on, I took it to the dealer, and they told me my timing chain is off by a small fraction. I have the codes with me. they are charging me $5,000 :( I can't afford this. My cars runs great still with this problem and I do not hear any rattle noise when I drive it. Does anyone have a good mechanic in the Los Angeles, CA area that I can take my car to look at? I know this is a very delicate replacement and the engine needs to be removed. I will really appreciated. thank you!
