No wonder the Dipstick hole in the oil pan was leaking

After bracing and preparing for the job I have been dreading doing since I got the truck (and it was leaking pretty good way back when), It was time to reseal the Dipstick hole in the oil pan.

I accumulated all the necessary parts, and braced myself to see if I was going to drop the flange into the pan.

Success! all went without a hitch. And once I was done, It was amazing that it wasnt leaking more than it was. First I was so glad I sprung for a new nut, as the old one was far more mishapen than I would have ever imagined. And the o-ring was broken, and swollen to 4 times the size of the replacement o-ring.

Here are some pictures of the aftermath

Nice work. what did you use to keep the flange from falling into the oil pan? i have the same problem but i tightend the nut a little and stopped the leak (temporally). Hoping it will hold till summer. Did you order a kit, or ?

Dieselorings.com sells a nice kit for this job for around $40 I believe that includes everything needed, including a way to hold the flange so you don't lose it in the pan.

Yes, I basically bought the parts I needed to replicate the Dieselorings kit. It worked out that I got everything I needed for the price of the kit, without the shipping and the wait. I had some gasket material, so I made the paper nut gasket myself. I also ended up with a way bigger tube of Loctite 515, but I will use it for other stuff.

The wirebrush works well for holding the flange. I bought one for 1/2" pipe, so it was a little big, but it was not going to fall off.

I know, old thread.
Mine isn't getting attention :
So I'll resurrect this. Any tips on doing the fix?

Sorry for not responding sooner, I deleted all my subscriptions somehow, and didnt get an alert.

I did two other dipsticks after doing this one.

I think that either the inside flange on the black truck (the truck this was based on) was either distorted or I got a bit of oil on the inside o-ring, because its got a bit of a leak to it. If I did get oil on it before adding the red loctite, I think that might be the cause of my leak.

The other two have been holding up fine. They were never touched, attempted to be tightened, so I think that if they are tried to be tightened, thats what warps the flange and nut.

The Dieselorings.com kit has a good pdf download for the instructions, that is basically what I did.

As for tips, just make good and sure the wire brush is wedged good into the flange, and give it a bend, so that you can hook the brush on the hole after removing the nut. Also, do it with the oil drained. I did not drain my oil, and thats how I think I may have contaminated the flange before applying the loctite to it.

No big deal.
I was going to just use needle nose vice grips or something else to hold the flange up there.
So basically just keep oil off the flange o ring to keep it from expanding, otherwise it won't seat good?
And use red loctite threadlocker to keep the nut from backing off later?

I didnt use the vise grip, because I thought I would damage the sealing surface of where the tube goes, causing another leak.

I thing the oring did the best it could, but the flange was distorted enough that it didnt seal. I was hoping the loctite would help out and make up the difference. I was wrong.

The loctite 515 (same as in the dieselorings kit) was more of a sealer, than a threadlocker. Its kinda runny, but thickens over time
