Check this before your powertrain warranty is up!

I've ran into a few VQ35DE motors so far that have had oil pooling between the spark plug tube seal and valve cover when removing coil pack over cylinder #6.

In the video it is an extreme example of what will eventually happen if there is a leak that goes unchecked. I was just about to swap my plugs out at 60k and also spotted oil pooling at cylinder #6. It's at the dealer right now and they already replaced both valve covers under warranty. I highly recommend pulling out coil pack #6 and confirming you don't have a leak there while you're still under warranty. The spark plug tube seals aren't sold separately, they only come with new valve covers.

I think leaks at other cylinders can happen also, so it's probably a good idea to go around and check all of the spark plug tubes.

That's good to know.

Thanks for the heads up ByThaBay. I wonder if the problem is prevalent in the FX as well?

I haven't seen any FX with that problem.

I need some serious help. Does anyone know what you need to remove in order to remove the valve cover?? I have it loose and the only thing seems in the way is the center huge metal portion. All plugs and screws are out. Thank you everyone. Its on the drivers side.

Nothing to difficult,just tedious, You have to drain coolant that flows thru air intake assembly and remove air intake assembly(new gaskets), unplug the throttle body, I suggest you download the manual. A lot of caution !!! is expressed in torqueing the bolts during the install of air intake assembly( alumnum ). I had to do this procedure I had the same problem expressed by Bythabay (same cylinder leak). My warranty was up 108K mi. I installed a Motordyne spacer while it was apart. You can go to thier website and get the removal and install of air intake. BythaBay also has a video on the install which I recommend highly. Hope this info helps.
