Not sure if it has a gasket problem, but my truck misses terribly when idling and makes soem pinging sounds when accelerating
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.
increase oil consumption, and wet floor passenger side.

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