Is it just pushed in, screwed in? I need to get the one off of my '86 cavies engine block, but can't get it to budge. I'm afraid the more I mess with it, it's just going to break off. Does anyone know if a reman. short block engine comes with a dip stick tube attached to the engine, I'm leaning towards no. Does anyone have a dipstick tube for a 4 cylinder for sale? I'm interested in buying one.
