I've also seen some higher milage motors with it under the valve covers that had no problems.

Mung inside valve cover, is normal on car that doesn't routinely reach operating temperature. White stuff in lifter valley is not normal. Are you loosing coolant? Drain oil and see what comes out.

Let's start with why you pulled the intake off?

That could be the reason for the milky stuff.

Is the motor in a cold place? (sorry if that sounds stupid) but in the winter time this often happens to oil in a vehicle.

When I worked at the tire and lube express almost every car that came in in the winter looked like that under the oil cap. I bet it is just the cold weather, especially if it is sitting outside.

Looks like normal condensation drive it 200 miles and see if you loose any coolant but its not a headgasket if you dont have any driveability problems..or pressure test the cooling system with the intake off and see if its seeping in the valley that could be possible
