oil leak at the dipstick tube

[tstorm]

I HAVE A 1976,F-150,4X4, W/360. WHAT OR HOW DO THEY SEAL UP THE DIP STICK TUBE AT THE OIL PAN???

I had mine pull loose once and I cleaned up the tube and the hole in the pan and used a little gasket maker to help hold it in place...it hasn't been a problem since.

I had the problem too. Turns out the original tube had a taper too it that was too long. I can't remember for sure, but it was tapered a bit either by forming it, or grinding it. This was probably done to start the tube in the hole in the block, but the taper was too long and it wasn't tight enough.

I trimmed a bit off the end, and used some RTV and it was fine. Have to be careful with the RTV. Put it on the tube, not the hole, or some could get pushed inside. I think I had to bend the support tab a bit as the tube was a bit shorter than before.

Since then, I switched to an oil pan with a nipple on it for the dipstick tube. Silly me forgot about sealing off the original tube hole in the block until after the new oilpan was on, so I didn't dare thread the hole for fear of filings getting inside. So I found a short bolt and RTV'd it in. No leaks from doing that either.

On the other hand, I do have oil leaks elsewhere........

Mine used to seep oil where it's riveted to the pan also. I don't know how much welding experience you have but I brazed mine back together. It's too thin to weld.

Mine was seeping from where it is riveted as well, as it was on the truck we used epoxy to seal it.
