Should have bought a Ram!

I bought an XJ Cherokee with a bad motor that was 150 miles away. We went to get it with the F-150 we just bought from my brother-in-law. Truck has (had?) a 302 with a five speed. Hooked up a borrowed car trailer and went to get the Jeep with about a 25mph cross-wind. We were only able to do about 55-60 on the way down. The trip while loadedback was ok while the wind was behind us, but when the wind hit the side, the truck could barely manage to maintain 55. We got within 60 miles of home and noticed a significant loss of power. Stopped in a small town when the oil pressure dropped and engine acted like it was hot, although the gauge said it wasn't. I added two quarts of oil and let it cool down, then headed home. A quarter mile from home, oil gone again. WE LOST TWO QUARTS OF OIL IN 30 MILES OUT THE EXHAUST!!!! Only thing I can think of is the intake leaking. Other thoughts would be appreciated!
