Well I have 66k on mine now.

at 50k i had all the fluid changed. at 62k I had the wheel bearings repacked (another try at getting better mileage).

I also have a K&N filter, but I don't have a heavy foot by any means, and 90% of my driving consists of to work and back which is strictly highway.

I will check into the intake gasket. I do know it looked like it had some black film around the gasket last time I was under the hood.

Also that is a good idea about the brakes, I know when i turn around corners I get alike a wearing sound coming from the front.
