I have a 94 MX-6 V6 it has about 140,000 on the engine.I was driving ont the interstate and had the cruse set at about 70 when the enigine stalled.The momentem kept the engine turning till I pushed in the clutch.Smoke was going everywhere.I got pulled over and opened the hood and the coolant was coming out of overflow jug.I let it cool down and tryed to start it ,but it wouldnt turn it was stuck.I towed it home and fiilled the coolant back up.It started but sounded like it was missing a few cylinders.I checked for cracks or holes in the block and the head gaskets and the timing belts.All of them are good.I need some ideas on what else it could be.

 

if the fluid was coming out and it wouldnt restart. it soulnds like you overheated it, it might have blown a head gasket. you said when it restearted it sounds like it is missin cylnders, they might be full of coulant, sometimes a head gasket can blow and it will not show leaking on the outside. check your plugs for coulant and check your oil for any whitr foam, if there is white foam or milk looking it is a blown head gasket

Gook luck

 

Pull all of your spark plugs and crank the motor, see if fluid comes out of any of the cylinders. Also do a compression check on each cylinder (gauge screws into the spark plug hole) If you blew a head gasket, you'll get low compression readings.
