Ticking, knocking or rocking sound
Hey guys and girls. I own an 05z with 155k miles on it. Recently I started hearing noises when I turn the car on in the morning. It sounds like it's coming from the passenger side of the engine. I've done research but can't pin point on what the problem could be. Anyone had this problem already? I'm leaning towards engine knock but not too sure. Any advice, help? I have a sound video that I can try to upload our I can put it on YouTube so y'all can hear it. Please and thank you.

I respectfully ask the question: "What was the purpose of your snide response??" The OP posed a reasonable question that he has researched and yet is still unfamiliar with the possible issue. There is nothing wrong with that.
It is your type of remark that further diminishes the already declining signal:noise ratio on this forum.
If you are indeed the sage mechanic that your response seems to indicate that you think you are AND you can render an accurate e-diagnosis without actual hands on, then by all means, POST IT. Doing so in this manner gives everyone reading the thread information that they might be able to use in the future.
Negativity of the kind in your response benefits NO ONE. All it does is let everyone know that you really don't know the answer (and no one can without actual hands on the problem) and that you are merely arm chair quarterbacking and sniping from the comfort and anonymity behind your screen and keyboard.
If one has nothing to contribute to a thread, just don't say anything. If you do have info - even speculation - make your contribution worthwhile. Your response turns everyone off - new members, salty veterans, and everybody in between. The more positivity on the forum, the better it is for all.
Answer a question in the way you'd like to be responded to. With respect. You may indeed be a veteran, but you started at a point of unknowing as well.

If it lasts for a half second to a second and then disappears right when it fires, its probably the timing guides and tensioners. My 05 has started making a little rattle (if you can imagine the sound of a chain being pulled across an edge of something) for a split second on startup and im at 152k. it goes away after a second, but i imagine in 20000 more miles it will be time for a rebuild. I am just going to rebuild the whole assembly when i put the cams in.

Sorry for the late reply, it sounds internal. During warn up it sounds like a diesel. After coming to full warm up it goes away but comes back for a few revolutions while driving. I haven't moved it for about 4 days because I'm afraid it's something serious and I haven't had time to put my hands on it. I'll put the video on YouTube and send y'all the link here in a few. I've done more research people day fuel dampers bit other say that's not it. I'll post up the video and link tho.
And thank you everyone that's willing to help out, I really appreciate it!!

350z engine noise:
That's what I'm getting, sorry for the bad graphics but that's the noise. I do have a CEL but because I have test pipes. And no misfires at all. No change in rpms while at idle either. I'ma drain the oil today to see if I have metal shavings or not. I'll keep y'all updated!! Much love guys!!

Do you have a massive crack in your test pipe thats a pretty wierd sounding z. If you think its internal I would get it towed to a shop. It doesnt sound as bad as the jeep grand Cherokee I had when the connecting rod broke and the engine kept running for a short time. But it does sound more like a diesel then the 2013 cummins 6.7 that I drive all day.

Exhaust leak can cause that noise? I'll reinstall the test pipes but I've been running with them for about 3 months no problem. My buddy has a g35 and he just started getting something similar like that.
