    What are you guys doing for removing the broken bit of dipstick tube stuck in the block? I tried to grab with some needle nose plyers but cant get enough bite. Just thread a screw in there and pull out? any other procedures that wont drop metal into the pan?

    No personal experience - 1) thread a tap into the stub and pull on that. 2) make a slide hammer from a piece of (threaded?) rod you grind a hook into. Place it down in the stub and hook the bottom edge. Put a nut on the other end and hammer it out with whatever you can improvise - crescent wrench, piece of steel with a hole in it, whatever.

    I still have the tool from years ago. I heated the blade of a medium/small slotted screwdriver red hot and bent the tip a little more than 90 degrees to form a small hook. I immediately quenched it in water to temper it.
    It would snugly go down the broken dipstick tube and cant sidways to lock under the piece. I used a few radiator clamps to attach it to a slide hammer.
    A couple upward taps and and the piece came right out.

    My 225 V6 does not have the extended tube and didn't come with one. If you can't get the broken piece out then leave it alone and just re-mark the dip stick for the shorter stick and cut off the bottom or find the original dip stick for the engine like mine that is flush with the block.

    I have a 4.3l stick and tube i am experimenting with so hoping the block hole is a size that the tube can fit in :)

    What are you guys using for a seal to the block? I would be afraid of dirt and garbage slipping in under the dipstick handle.

    The stick has a cup/washer that is slid over the stick that has a felt seal that closes the gap. The cup is staked on the stick so it does not slide.

    how about welding a bolt to the stub and use a socket on it? A couple tacks should do it.
    Weld won't stick to cast iron.
    Also might weld a washer to it put a bolt down the tube (or cut off a head and tack head to washer.
    The heat may help loosen the tube
    Brain storming here, I bet a hole drilled in a piece of 1/8 " thick x 1/2" wide stock (3 or 4" in l3ength could also be tacked to it and you'sd have a handle to work it back and forth.
    Before you do anything squirt a little rtv in there to trap any shavings.

    As mentioned, some engines use a short tube for the dipstick, and others just seat the dipstick on the block, usually with a felt washer in a cup on the dipstick. One of my old engines used the felt washer style with no tube and I didn't think much of it, until I later pulled the oil pan. There was a layer of sand in the bottom of the pan. This was when I lived up at Hatteras and was on the beach most of the time. I've used a short tube type dipstick arrangement ever since.
