    Excessive engine oil consumption, 1 quart every 50 miles. No visible smoke or leak. Local dodge service manager referenced a technical service bulletin. Replaced plenum gasket and required parts in service bulletin. Problem fixed.

    driving at normal highway speeds average of 200 miles consumes up to more than 1/2 quart of oil but truck feels very strong and does not feel any lost power at all except when aceleration a small clicking noise and the result of lost oil in the trip.

    Now that I know the problem I will get right on it.Used 2 quarts of oil on a 200 mile trip. Had pinging at high speed and the check engine light flashed a few times. I also recently changed plugs and noticed alot of white build-up on the plugs closest to the carb. Thought it was coolant leaking. Glad to have this forum. Love my RAM Sport.

    excessive oil consumption, replaced plenum gasket, some technicians I find out know reccomend replacing the aluminum plate, due to warpage.
