pull the motor? Huuuuuuh. I replaced my crankshaft seal in under an hour.Just hope its not a crank seal because thats what just happened to me. Car didnt leak from the seal till after I put on a dorman valve cover then it blew my seal. Im having a gm cover put on this week and my mechanic said that the gm cover might stop the crank seal leak. Im having my doubts on that but well see. If it dosnt work then I guess ill be spending 700 $ for him to pull the motor to fix the seal. I also did the pcv v2 kit at the same time.
