Coach is in at Cummins where a leaking(coolant) head gasket(ISC350E) was diagnosed. Insurance inspector says the leak is seepage and is not a covered repair. The exact wording of the policy is "leaking to a drip" in order to warrant a repair/repalcement. How much seepage should I allow for this engine? BTW, Cummins replaced this head 3 years and 17,000 miles ago as the original was cracked.
What would you do?
