Oil dipstick tube install?

I didn't remove all the chrome on mine. I did bevel the edge with a file, though.

The best route that I've found is to use a screwdriver with a plastic handle that you don't care to beat up a little, slide it down into the tube until the handle butts up against the opening, then hit it with a metal hammer. It will mar the screwdriver handle a tiny bit, but it gives you great control with the handle to keep it centered and it keeps the the install pressure/ impact centered, also. First shot, no problems.

When they are straight, the tube looks and is a bit close to the head. Just let it go in close to the head/ block at that short distance from the head, then bend it out to your liking a bit, after it's in. Don't go too far forward when you bend it or you'll have fun getting the fuel pump in.
