Knocking normal?

Ticking or knocking? Your description sounds more like ticking. Fuel Injectors are quite noisy and it very well could be them..Not much you can do to quiet them..

Do you know if the dealership did in fact use Nissan Ester oil? Most dealerships do not. This can cause a ticking sound in the valves.

I asked them for it specifically and the paperwork says Nissan 5W-30 EP and it was $11.99/ quart which is what I've read that Nissan Ester oil costs. The Nissan part number is 999MP.

This is why I like doing my own oil changes. Half the time you don't know what the dealer/quick-lube is filling with. I don't trust most service managers\techs at dealers, so even if they told me they filled with the requested oil I would still be questioning their trustworthiness.

Ya I just purchased my Rhino ramps, and all my tools so I can start doing my own changes. I should have sharpeed the oil filter before my first oil change. Especially since my first one was free, I'm assuming they didn't use Ester oil or change my oil filter since I went in at 856 miles. Well I didn't mean to turn this into another oil thread, but I'm switching to Redline after 5000 miles. I had the tapping before, went in, they tell me ester oil will rid it completely, and it obviously did nothing.

So I finally was able to get time to post a video of what I am experiencing. I hope that this will in fact go away with time or a couple more oil changes as I have been informed, but none of the other Z's I've heard sound this way. Any knowledge would be really appreciated. So normal sound or not? Doesn't sound so normal to me... Oil temp is sitting right at 200.

Probably not a knock. But, Modshack is correct... the injectors do make a ticking noise. I haven't noticed this. But when I started my engine after 3 months of storage, there was a slight noise for about a half a second or so. I attribute that to dry start and nothing else.
