Hey all,
I have a 4.5 Johnson that siezed up. After it cooled it freed up no problem. However, I found water and mud in the cylinders so I replaced the head gasket and side plate gasket. The pistons and cylinders looked good except for a couple spots of mild scoring from the overheating/siezing episode. So I checked the rings. They are all nice and free except for one that acts a little sticky. After putting her back together I did a compression check on it cold. I'm getting around 60 PSI per cylinder. Is that normal on a cold engine? I hope she'll start so I can consider my work a success. Any thought?
Thanks.
