My lights do the exact same thing...just for no apparent reason. Some days it does it..some days it dont. Then it wont do it again for months.
Location of the PCV valve coulda been better too

I don't currently have the dash problem...furthermore, I have no idea what it even looks like (the "curling" problem). I've just got other problems currently
