Jack slipped, crushed oil pan.

Pulling the front axle out of my parts jeep. I noticed the jack stands were sinking into the driveway and leaning pretty bad. So I figured I'd jack it up before they tipped over and the jeep fell (possibly on me).

As I was getting the jack under to remove/reposition the stands, the jeep fell off of them. Landed on the LCA brackets and oil pan. There is a noticeable dent in the oil pan. I have it jacked back up and sitting on a 4x4 beam for the time-being.

I was planning on selling this motor, since it was a great running motor. Could landing on the oil pan have caused any damage, aside from to the pan itself? Is it something I could check by pulling the pan off?

Maybe damaged the oil pump and/or pickup but I wouldn't think it would hurt the bottom end. Should be easy enough to see by pulling the pan.

What will I be looking for in the pump/pickup?

Look where the dent in the pan is, then when you pull it see what's in that area. The obvious would be a dented or badly kinked pickup tube or a dent in the pump itself.

Yeah, just pull the pan and inspect. See if the dent is near the oil pump and/or pickup. If so look for contact points/scuff marks inside the oil pan and on the pickup.

It's right in the middle of the lowest point of the pan. Where approximately is the pump/pickup?

On this particular motor im not sure, but traditionally it is towards the back of the motor and hangs out below your crankshaft...

Here is a V8 with the pan pulled. The round guy towards the back is the pickup.

The pump extends into the sump of the pan
