Hey! I have an 06 350Z with only 14k miles and when i pressurize the engine as I am shifting(sounds like the lifters or the values). I hear a chatter and it happens in most gears I have had it in the dealership now 5 times and they even rode with me and heard it but can not tell me what is wrong.
I never put cheap gas in the car...always Premium. So if you have any ideas let me know. I can't imagine this is just the way this engine sounds but open to what you have to say.

Does it chatter when you step on it? or when you upshift? if its when you upshift im pretty sure it's normal. our cars talk alot

 

Once I come to a stop and I place it in first and give it gas and pressurize the engine the valves start to chatter like bad gas or low oil- and does it going into 2nd as well. It also does it when I step on the gas when I am in a gear...the same sound.

 

I know this is halfway a stupid question, but are you sure you haven't had any oil consumption issues which may have affected the valves at all?

Maybe I missed it but do you have a manual or automatic?

 

I am having a lot of oil consumption. I do not drive the car that much maybe 100miles per week, if that and I am noticing that i am having to keep an eye on the oil. It would appear to be burning oil more than any car I have ever had. I just chucked that up to my first sports car! But not a problem thanks for bring up a good point. I have really tried everything I know that I can do to stop the chattering! I did just find out there is a class action law suit with the 2006 Z's having to do with oil consumption. Not sure if this is all related to my noise or not? Who knows?

 

when you do what to the engine?

 

Check the oil consumption sticky thread at the top of this forum.

 

Well, as you might imagined the oil was low on my z- i had just had the dealership change the oil not even 500 miles ago and it was 1.5 quarts low. I have now started an oil consumption evaluation through my servicing dealership. We'll see where it goes but the service manager notified me that Nissan has issued a flag on my particular 06 350Z (HO = High Output) manual transmission for excessive oil usage. Which I am gathering that the low oil is causing me to hear the VTC Sprocket. So here i go down this road now...uugghh! Crap! They are talking about wanting to change out my engine.

Welcome to the club lol. Ive been through 3 engines. Two different versions. Each newer version was worse then the last. Im currently lemoning my car now. =/, My recommendation, get rid of this car ASAP. It will just continue to burn through oil, my situation has never gotten better in the 1 year ive had this problem. Until now, which is a vehicle buy back =/
