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.

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.

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

Plenum plate warped, burning 1 qrt every 200 miles, knocks at Idle, also test your Oil dip tube if you are getting suction down that tube time to replace the gasket and plate ... good luck
