302 blown

I have a 1992 F-150 with a 302 that has 166000 miles on it. This motor is a screamer and i'll admit I pushed it too hard in 3rd gear trying to pull a hill. The motor had slowly been losing power for a while and it finally gave out. Blue smoke issues from the exhaust and the motor jumps erratically on idle. But in higher rpms it still runs, although with a significant loss in power. Does this problem sound like a burned ring, bad valve, or something else? I don't think I did anything like throw a rod, because the motor still runs. Any help would be appreciated. Thanks

Bet you lost one or both rear cylinders. Burned the pistons or spun the rod bearings. Better tear it down before it does more damage.
