OK guys I was going to take my piston and sleeve out of my K 4.6 but could not get the piston out. Sleeve came right out (being that it is so new) it just pulled right out of the top. Can't seem to get the piston out. I wiggled and tugged and pulled (ever so gently) I know that sounds bad lol but BACK ON TOPIC. I can't seem to get the piston out, any suggestions? Just want to give the motor a good cleaning before I break her in. If I can't take the piston out could I just spray the crap out of her with nitro clean?
