I've had a srange thing happen to my stock 51 Mercury with merc-o-matic. It has been driven very litle for the last 8 months. Took it out of storage and drove about 30 miles on the freeway. Ran ok but stalled in traffic when starting from a stop. Worked on reposistioning the the electric fuel pump to tuck it up further in frame. Noticed a slight tick from the valves so put 8oz of marvel mystery oil and drove around
or a while.
Six hours later went to start her up and no start. Turned out I had zero compression in all cylinders. Pulled the heads and found three stuck valves. I haved pulled the valves and they are not pitted or burnt.

My questions is has any one ever had compresion all all cylinders fail so suddenly like that and what is likely cause?
