Well ya I dont like your answer because you're basically saying that engines tick. Not true. I have owned multiple new cars that have sounded like they should. Plus, you didn't even answer my question regarding valve adjustments, so you really didn't offer up any valuable information, just a dumb remark. The answer I was looking for from the community is clearly posted in my original post, if you cannot decipher that then

the only adjustment that can be made would be reshimming the lifters which would cost a hell of a lot and require both heads to be completely torn apart. they could pull your valve covers and check the clearances first with feeler gauges to give you some piece of mind but that would require tearing the top of the motor apart, and i'm not 100% sure whether or not that would require disconnecting the vvel actuator sub assembly which nissan says needs to be replaced if it is ever removed, if they mistakenly take apart the ladder assembly you will be in for new heads as well. your best bet is to keep trying for warranty if you don't like it. It might be a problem with the hydraulic lifters if there is some air trapped in them that can't be bled out and that would again require tearing the heads apart. if it's only coming from the very front of the engine it might be a problem with the chains or tensioners but that is highly unlikely.

Thanks man, very informative! +1 rep for you!

Hey, isn't that what I said? Go download the service manual like everyone else and read it. Then start turning wrenches; that is if you know what a wrench is.

Ok, this is getting a bit childish. I wasn't looking for a basic answer like "go try for warranty, or "engines tick." My original post asked specifically for technically inclined people if they could answer a valve adjustment question. You never once even said anything pertaining to my question. I got my answer from 1slow.

So, are you now going to tear down your top end seeing you have an answer? You could have found the answer very easy if you had bothered to read the service manual or google. So keep trying the warranty route because your mechanical knowledge is obviously limited to attempt a DIY. Have a nice day!

Dude you need to pay more attention to detail. I never once said I was gonna attempt a valve adjustment myself. I just wanted to know if it would have a chance at fixing the ticking. Btw I am a mechanical engineering major, so you can stop with the half assed attempts of trying to outwit me. Now..

AND have a nice day!
