1985 258 CJ-7. Driving back and forth to Atlantic City every day. Maybe a 1/4 cup of engine oil drains down over course of whole day sitting from rear of engine. Replaced valve cover gasket-no leaks. Rubber boot at clutch fork rotted away in short order. Clutch has low miles. Boot replaced at clutch time. Got 3 books, read all three. Any recommendations?? Tanksssssssss.
