Under Valve Cover Pic + bonus VQ35DE 162,000 miles #4778905

Just replaced some weeping valve cover gaskets and spark plugs on my 2004 Nissan Quest VQ35DE. Oil used has been mostly Pennzoil Platinum 5W-30 or 0W-40 lately with occasional OCIs of Mobil 1 0W-40. I probably have used Castrol or Valvoline a couple times. Manual recommends 3,750 severe service OCI, but I usually ran it around 5K miles or so depending on weather and my availability to change it. Lots of short trips to the elementary school/grocery store (one or two miles each way) with a highway run usually once a week.

I was pleased to see how clean the intake valves were. Fuel used is/was usually the least expensive lowest octane available (Maverick or Smiths/Kroger typically). No idea if either is Tier One. Have rarely used any fuel injection cleaners and have replaced one injector in the van's 162K miles. I bought it about 8 years ago with 73K on the odo.

Impressive! all the more for the valves given lowest price fuel and no routine of injector cleaners. I guess we are brain washed on those products crazy

This engine needs to be flushed with a gallon of pure MMO so it will be so clean you can eat off it!!

Looks good for that mileage. My M35X intakes looked worse at 23K running on local garbage gas, my brothers looked perfect at 100K running Shell 93 so yes I suspect long term tier 1 use.
I had both apart looking for the source of high fuel trims. Both had the same issue but his was much more diabolical than mine.

Edit: I am oil change maniac my engine is spotless, my brother couldn't care less his is a varnish and deposit nightmare.

Looks good for the mileage but just wondering -- does your engine only call for 87 octane then?

In my area/altitude, regular gas is usually 85 and mid-grade is 87. I pretty much always get the 85.

I was wondering the same thing. That engine, in other vehicles, the Infiniti G35 for example, "recommends" using 91 octane or "premium" fuel. Maybe they just tune them differently based on the vehicle it is in ? I'm thinking that Nissan isn't going to recommend or require premium fuel in a standard minivan....

Looking clean!

My old Infiniti also recommended using 91+. In the beginning, I used 87 but it made the engine slightly ping. I started using premium and the car ran very smooth.

Intake valves are clean because of good ol' port injection.
