With those compression figures (especially after oil in the cylinders), your chance of getting it started are mighty slim. I don't know the factory compression on a 6, but it's got to be close to the 110 lbs spec'd for the V8's. They will run OK at anything over 65, but below 50 and you've probably got real problems inside. The only chance you may have is if all of the valves are stuck. If that's the case, you might get lucky if you can get 'em freed up. I've never been that fortunate.

Also, I hate to contradict anyone, but I think it's a little too late for a leakdown test.
