Oil dipstick tube

Boy these are a lot of fun....spent all day yesterday, but finally got the
old one out and the new one installed! For removal, I could not get enough
umph on anything sliding to get the old one out. What I ended up doing is
inserting a bolt into what was left and clamping vicegrips as tight as I
could get them (which was pretty darn tight, onto the section with the bolt
in it. Then crawled under the coach, had it jacked up (centered on the
engine cross member) and supported with 4, 3 ton jack stands (can never be
too careful) with all 4 rear tires blocked and the front wheels under the
side rails (again I am paranoid when it comes to potentially being crushed
to death). Under the coach there is just enough room between the oil pan
and transmission to insert a long 18" 3/8 socket extension and have it rest
right on the vice grips and tube. Then just some gentle tapping on end with
my trusty general purpose tool (hammer) it slid right out. Ok it slid right
out the second time, the first time the bolt and vicegrips just ripped the
remaining rusted bit of tube off, but then I had good tube to clamp to and
out she came! To install the new section of tube I acquired some 2000deg
paint from my local ACE store (did not know they made this high of temp
paint) and painted the tube above the lip (part that stays out of the oil
pan), oiled up the tube below the lip and correctly positioned it. To tap
it in, I used a 3/8" crowsfoot (I think it was 3/8) and socket extender
then just tapped the socket extender to set the tube in place. It started
kinda difficult but after an inch was in it just slid in with just a little
effort.

I have never done this on a 455 or a 500, but have removed dipstick tube from other motors using a method I learned from a crusty old mechanic that I
knew 40 yrs ago. Basically what is done is to use the new dipstick tube to push the old broken off tube down into the pan. You start by draining the
oil from the pan. Then gently grind or file the the tube flush with the block. Snake a long piece of baling wire through the new tube, through the
old tube in the block and down and out of the drain plug hole. Using a plastic hammer, firmly push the old tube down into the pan and let it follow
the wire down and out of the drain hole. The is obviously for when all else fails and the next step is to take the engine out. This worked for me
several times. Also didn't work once when the tube was so tight in the block that it wouldn't move. Pulled the engine and did a rebuild while it was
out. JWID

I did the same thing once, only I left the piece in the oil pan and installed a magnetic drain plug. I found the piece attached to the plug on the
next oil change.
