Does anyone have experience removing the dipstick tube on a 2H. I have disconnected the top bolt holding it to the exhaust manifold but I can only get about half a turn before it hits the block on the other side. disregard the oil fitting on the alt, that wasnt mounted when I was unthreading the tube. Is there a trick to this I didn't see anything in the FSM and hopefully don't need to pull the entire engine apart to get the dipstick out..
