I just noticed the other day while draining my oil I had to pull the oil dipstick out for the oil to flow smoothly. I also noticed the dipstick and oil fill plug have o-rings on them to seal air and oil. Why would they do this?? Down the road with many miles on the car not you only have to worry about an oil leak but now you have to worry about an air leak from the valve cover gasket? :dazed002: Also where is my trans dipstick?? I see the fill port but no measuring device???
