I got the passenger side spark plugs out.
Doing drivers side today.
Engine has seized up, noted the day I got the car home.
Car was in 1st gear when I let off the brake, and engine did not spin, could not get it out of gear, rollback had to help to get it into neutral!!
Getting the rest plugs out then soaking the cylinders with WD40.
It looks like cylinder 1 took on water, cylinder 2&3 were dry.
I will be updating this thread, as situation updates.
