it was on its left side for about 2 hours. we tried to start it but its locked up. so should it just be the same procedure as if it were hydrolocked with water? just pull the plugs and turn it over until oil stops shooting out, then an oil flush? anything else that i should do?
Thanks

Hopefully you didnt bend a connecting rod when you tried to start the engine.
Should be the same process, pull plugs, crank over, put them back in. It will smoke until it clears the oil from the cylinders. shouldnt have to change your oil, just check the level.
If it doesnt knock, you should be fine.

The procedure for getting engine running is as described above. Just pull sparkplugs and turn over and shoot out oil. Re-install plugs, top up oil, start, and expect to see a ton of burning oil for a few minutes.
The bigger problem you may have is that you tried to start it after being over for hours. That is a VERY bad idea. Basic laws of physics on earth says that liquids cannot be compressed, think hydraulics.
By starting an engine with cylinders full of oil, you may as well be starting an engine with the cylinders filled with concrete. It is highly likely going to bend connecting rods, destroying the engine.
HOPEFULLY you have a very tight engine, and very little oil made it past the piston rings to fill the cylinder during those hours upside down.
You may see in some buggy vids of rigs rolling, everyone running over, and getting it back on its wheels fast. That's so oil doesn't have time to get into cylinders. You can start and go again.
In your situation, with being over for hours, it was imperative that you pulled the plugs before trying to start.
Good luck....be interested to know how it worked out? JK or 4.0?

Is the starter really strong enough to bend anything though? I assumed if anything you would fry your starter before you bent a rod...? |

Should be fine once you pump out the oil and refill. Mine was. Twice ;-)

Think of it like this; the mass of the rotating assembly suddenly coming to an abrupt stop. Even though it hasn't far to travel, theres force behind it. Also consider this; if your vehicle is in gear, no spark or fuel, and you turn the ignition, the starter will rotate the engine even through its compression strokes. Which in turn, moves your 3000+lbs Jeep. Starters are very powerful. |

quick update.
we pulled the spark plugs in the mechanic shops parking lot. considering when it was hydrolocked water only spit out maybe 10 feet at most, we thought 20 feet would be more than enough distance for the oil to shoot out. wrong... it was cranked for less than 2 seconds, and managed to spray the entire box of a newly painted f-350 with a nice coating of oil...
so the rest of the day was spent scouring the box of a pickup :/

Ford's need lots of undercoating.  But seriously, how is the jeep running now? Considering you have hydrolocked it twice now.  |

It can turn over a 300lb rotating assembly against cylinder compression, and it can drive the entire Jeep forward when in gear. Bending a rod is within that range of torque. As far as the update goes....does the engine run or what? lol The oily Ford got done a favor! |
