"I" would pull the engine, put it on the stand and flip it upside down so you can successfully seal the entire bottom of the engine, instead of fighting everything that the oil pan will hang up on trying to get it out from the bottom.
I agree.
I did this 2 years ago a couple days before I left for Carlisle lying on my back in the garage. It's a hassle to get the pan out then back in again.
If I had to do it tomortow, I would definitely pull the engine and put it on a stand. Wouldn't even think about doing it in the car again.
