Ran my perkins
4-108 for an hour last time I was on boat in December, ran great. back on the boat today and motor
is seized. no water
. used breaker bar and pipe on pulley to try to manual turn and didn't budge. I could get an even bigger pipe but don't want to break rings. I'm assuming rings are seized to block but doesn't make sense why they would be.
I assume best plan now is remove infectors and put some liquid wrench or similar into cylinders?
In December I installed new heat exchanger
, tube bundle, exhaust elbow
, rebuilt water
pump">raw water pump. Like I said, ran engine
for an hour and all was good at that time.
