99 RR 4.0. dipstick is just under 28" long. each time i change the oil (7 qts) the dipstick reads about 3/4"-1" over the full mark. i burn little oil and haven't really worried about it because i regularly check the level and change every 4-5k miles. the top end was redone about 25k miles ago and i'm wondering if they put the wrong dipstick in. did a search and didn't see anything and was wondering if anyone knows how long the dipstick is supposed to be. not a pressing issue but curious. TIA.
