Pulling oil pan on 273

I agree with Jake. It can be done in the car but in my opinion the best results with you pulling engine. Whichever way you choose make sure the oil pan where it mounts (bolt holes) is as flat as pi$$ on a plate! Thats where most oil pan leak problems are.
Also if you do decide to pull it, maybe think of a few other "things" that need to get done at the same time?
Good luck
