Replacing Valve Covers... Should I Replace More?
Title says it all.
I have a 2003 mostly stock VQ35DE (non-Brembo) with just under 135,000 miles. Oil is getting into the spark plugs wells and messing with the spark plug ignition on the rear-most driver-side plug. I literally just had the Nissan Dealership install new plugs at the 130,000 mile mark.
Plan: Replace Valve Covers.
Extras thanks to tax return:
- Motordyne 5/16" copper iso thermal spacer
- MREV2
- R1 Concepts Cross-Drilled/Slotted Rotors
- Hawk HPS pads
Thoughts: Should I go ahead and tear off the heads and replace the head gaskets? I do not drive it recklessly, although every now and then I will go full throttle from 0 to "5 over" the speed limit. I have maxed out the engine (top speed) going to the hospital or racing to some other emergency 3 times in the 7 years that I've owned it. I have never had any other problem with the engine; just the oil messing with the one spark plug.
Random other upgrades currently on the Z:
- JWT Pop Charger
- JWT Clutch and Lightweight Flywheel

Thank you for the feedback!
I initially thought it would be as simple as draining fluids and removing a few extra bolts, but it looks like a hell of a lot more just for a few extra gaskets. The temperature up here in Indiana is going from mid 10's to mid 30's and I do NOT feel like spending all the extra time in the cold.
