Take the spark plugs out, clean them up, turn the engine over to spray the oil out of the cylinders, replace cleaned and gapped spark plugs, clean the oil off the engine, then try to restart. it'll smoke as the oil in the intake runners gets drawn back into the combustion chambers a little bit. You'll need to add some more oil, btw.

And hope you didn't bend a valve trying to start it with it hydrolocked.

Or worse.

You should have pulled the plugs and blown the oil out of the cylinders before turning the engine over. You could very well be on the market for a new engine now.

Once an engine has been turned upside down, oil gathers and seeps around the piston rings into the combustion chamber and eventually flow into the intake. I doubt you damaged anything on your attempted start up due to the fact that it "wouldn't even turn over". Which leads me to believe that the cylinder was fully filled with oil, saving you in the long run. The starter motor will not have enough power on it's own to bend valves in my experience. Follow the aforementioned steps to clear the cylinder of oil, clean the plugs, and also refill the crankcase with oil.

Heres a more relevant question: At the point that the jeep was turned over, how long did it run? Did you physically turn it off by way of the key?

If the starter engages but the engine won't fire, there's a good chance you tripped a fuel shut-off safety switch. These vehicles have them, correct? If so, look for a reset switch for that.

If the starter is not even engaging, then maybe some neutral safety switch or clutch interlock switch got damaged or the wires crossed? You have an automatic or manual trans?

Jeeps do not have a inertia/reset switch.

You would most likely break a push rod before bending avalve stem. Pull your plugs (drain any extra oil) then take off your valvecover and make sure you didn’t bend or break and of your push rods (not that bigof a deal).

GOOD LUCK

Well bummer. Would'a been nice if it had been something simple like that.
I'd heard that they didn't at one point in the past, but wasn't sure.

Thanks
