I recently purchased a 1998 Jayco Eagle class C, and have used it on three short trips this summer. Everything has gone fine, with only minor issues associated with a 10 year old camper. I am planning a trip to meet some family members about 9 hours away, and was researching a problem associated with warm engine start, and stumbled across all of the issues with "spark plugs" blowing out of the cylinder heads for this type of engine. Has anyone had any issues like this, and should I be concerned, as I'd hate to breakdown in the middle of nowhere. The camper currently has 58,000 miles on it. Any information would be appreciated. Thanks!
