Credit: Nisformance We are comparing the 2009 Maxima oil pump, with the 2002 Maxima oil pump, and the 2006 RevUp 350Z.
Without having to take the 09 motor apart I decided to buy a new oil pump. This is to find out what pump is in the Newer FWD VQ’s.

Outer Gear weight- 132 g
Inner Gear weight- 158 g
Has dots on the gears.
P/N 15010-8J101 $205.67





Outer Gear weight- 126 g
Inner Gear weight- 160 g
Has dots on the gears, Made in Mexico.
P/N 15010-7Y00A $31.17




Outer Gear weight- 134 g
Inner Gear weight – 166 g
Has arrows on the gears
P/N 15010-AC700 $183.64





The 2009 Maxima oil pump is $31.17! I was amazed by the price of this oil pump. All of the other VQ pumps range from 180-220. So why is this oil pump so cheap? Well the casting looks cheap with lots of flaws. One thing i noticed is there is a lot of play in the pump you can simply shake it and hear the gears hitting the case. Now this pump is brand new and the others are not. This 09 pump is the only one that has the “looseness” like that.
The weights are as follows:
02 Maxima O- 132 I- 158
09 Maxima O- 126 I- 160
06 ZRevUp O- 134 I- 166
All weights are in Grams.
As you can see the outer gear on the 09 has the biggest difference, this might be why the pump cost so little. The inner gear is not so big of a difference but its still 6g lighter than the rev up
All of the springs look the same, they all have 15 coils. And feel the same but I don’t have any way to test the springs.
Left to right- 06Z, 02 Max, 09 Max.

Of course, my ’02 valve covers are leaking at the spark plug tube seals, so I decided to upgrade. I went to the dealer and picked up a set of fresh ’04 3.5 Maxima valve covers.
Part Numbers (2004 Valve Covers):
Valve Cover Gaskets (required):
Bonus: The new valve covers come with a PCV valve already installed—so you can save yourself another $8. I didn’t realize that at first and ordered one separately, but at least I’ve got a brand-new spare now.

The kit does include its own sandwich plate, but I opted not to use it. The included plate felt cheaply made and, more importantly, it wasn’t thermostatic—meaning it doesn’t regulate oil temperature. The GReddy plate provides much better quality and functionality.
