E53 X5 Valve Cover Gasket

I have an 01 X5 with 140k miles on it, and have noticed a decrease in fuel economy recently. Fearing the worst, I decided to do a compression test and see what the problem was. After taking the ignition coils out, I found the spark plug wells full of oil on cylinders #1 and 2. I assume the problem is a valve cover gasket, but would this lead to decreased fuel economy?

BTW, compression test came out good, all cylinders @200 psi
