i had water get in the oil for the motor in my 1985 cutlas supreme and the motor locked up. now i was able to get it to turn over after about a year of sitting. i took the the spark plugs out and poured tranny fluid in the holes for the plugs and then with a fly wheel turner i was able to get the fly wheel turning. i put the plugs back in and tried to start it after about 3 seconds of the motor turning over it locked up again. the engine only has 83,000 miles on it but was mistreated before i bought it. what can i do to get it running again?
