Neep some help on a dipstick tube 66 -240

[slickmainer]

I have my friends 66 F100 2wd with a 240 (code A). i went to check the oil and the whole tube came off in my hand. It had some spray foam looking stuff on the end of it.

I don't know if it broke off and part is in the pan thread or what it's even supposed to look like. The dipstick has a part code from 1982, and there is no tab way to attach it to the block.


does anyone have a photo of the tube going into the pan? is there a nut that threads into the pan and that is how it is supported?

the nut stayed in the pan the tube came out


this was the dipstick in it

pretty sure the end of the tube is supposed to have a flare on it so as not to pull out of the nut. just guessing but it may have been shortened and the goo put on to accomodate the 80s dipstick.

the pic shows only the top end, not sure if yours is the same length

i got the old goo off the tube and it is smooth, no ridges or flares to hold a o ring or anything so i think you are right. Im trying some jbweld to get the tube to hold to the nut that is there. if that doesn't work i guess i'll try hitting the junk yard to find an original 240 tube.

I put an o ring on mine and tightened it down. I also flared the end with a screwdriver. It neither moves nor leaks. I also put a bracket on the tube near the top bolted to the lifter cover. Here is a picture, you might be able to see better what I am talking about with the bracket. I don't think you need one, I just felt weird with an unsupported dipstick tube.

easy to make a new tube out of 5/16 brake line, already has the nut and flare just get it longer than needed and use a tubing cutter on the top end after careful measuring of correct length.

That crossed my mind right after I posted. The o ring that I put on the tube between the flare and the nut is working still so I am not going to bother changing it.

Think I got it fixed with some metal putty. should hold till a replacement tube and stick is found for her.

That oil pan is off of an 80's ford ( or possibly someone put a 300 in out of an 80s truck) the 240s and early 300 have a short dipstick tube in the block. There should be a hole with what looks like a tiny frost plug, the original dip stick should go there.

My 65 240 has a 13 inch dip stick and the tube is only 3 inches long. It is also located between the distributer and the fuel pump filter. there we not any part numbers on the dip stick

The basic part number for a dipstick tube is 6754. Check eBay occasionally for NOS 6754 to see if one comes up.
