"I have 2001 crusader 7.4MPI's they began to get hard to start finally one just ran very rough before I wasn't able to get it restarted. I checked the plags for fouling and found both had plags that were fouled. The engines are fresh rebuilds and the builders used a NGK plug that was not called for by the MFG. One of the motors plugs were wet and slightly rusting as the motor sat for about two weeks. I replaced plugs in both motors and one ran fine, the engine which had the water wet plugs still won't start. What causes water to get on the plugs and have I damaged something. These motors have only 7 hours on them. Help please!"

"Those motors are famous for sucking in water through the exhaust system. Suggest you pull all the plugs, wheel her over good, then put new ones in and try to start her. But if there's water in the oil, don't do a thing 'til it's sucked out and replaced.
