All 95-up Maximas have solid lifters that are NOT self-adjusting, but Nissan does not list valve adjustment in the 60 or 90K mile services...I imagine they'd need adjusting by 120K miles, though.

Yes they all need to be adjusted
When you hear a lot of rattling or clicking noises coming from the top of the motor it is time to have them adjusted. They are shim under valve type springs, and are easy to adjust if you know how, it is just a big pain in the ***. They act like solid lifters in older motors, which to some older hot rodders believe that they give better response and better revability. I believe they don't work as well as hydraulic units that self adjust over time and can last up to 400,000 miles before parts need to be replaced. It is just that the motor is an older design, and solid valves take up less room, and it is a lot cheaper than redesigning the top end of the motor.
I have a friend with 88,000 miles and never had a valve job, and doesn't need one, my other friends were clanking at 30,000, but he races his car at every SCCA event he can find!
Nissan charges $380 for the valve job complete, or at least at my local dealership, that is what they charge.

Re: Yes they all need to be adjusted
Actually if they get too tight, they will need adjusting but will not make any noise. But it might burn a valve though.
