johnsps250 is gaining momentum as a positive member of FTE.
This one looks like it will work, always had good luck with stuff from McMaster Carr.

I've always had to replace the copper washer after a couple changes or it would drip. Next time I change the oil I plan to give this a try.

I don't know how much actually weeps out when I drive but there's always one drop clinging onto my drain bolt whenever I look under there.

This is timely since I am replacing injectors so I just ordered some (you have to order a minimum of 5). I didn't like the fact that you can't estimate shipping so see if it's going to be cost effective (you can call their customer service line though).

I like the Fumoto but I would always be worried of catching it on something and ripping it out (especially off-roading). Whether true or not I would always have that concern. So to get 5 of them for 1/2 the price of the Fumoto it's worth a shot.

Hopefully this is the solution to my issue. Thanks for the recommendation johnsps250. Reps sent!

Kind of odd that nearly every other fluid fitting on the engine has an o-ring seal, but not the drain plug . . .

I could also just weld that hole shut and poke a screwdriver through the pan when it's time to change oil. I could probably get about 12-15 changes out of a pan.

That's 3-4 changes a year, so about 5 years before replacing the pan. Hmmm...they're so "close"
LOL.....
I should look closer, mine is leaking but I thought that it was coming from my rear main seal. I changed the washer on the drain plug, but when the leak continued I assumed it was my rear main seal and not the plug. After reading this thread I need to take a closer look.

I have thought the same, but wonder if it is because it is taken in and out so often? I know o-rings don't typically do well being removed multiple times.

I got tired of the Ford washer & put the GM 6.2/6.5 Diesel aluminum washer with, looks like high heat silicone bonded in center,I had a handful left from My GM diesel days,been using them for years on several applications,never had one leak even when reused several times.

Got a part number, pic?

After all the time and money I put into the top end to stop leaks, it's crazy to see oil spots on the ground

Thanks!

I sprayed and wiped the sides of the pan with brake cleaner, including the bottom down and around the plug.

When the plug was wet, but I could go all the way around the pan and feel dry, I put the gold star on the plug

There is one bolt in the pan that leaks a bit, too. I plan to pull it out, squeeze a little Permatex ultra-black into the hole (maybe into the surrounding gasket surface 1/8" or so around the hole), coat the bolt with the same, and reinstall and give it time to sit and cure before driving.

Might not get it all, but should really slow it down. As I mentioned above, I can still get a dry pan after sitting a while, but after driving and such for a bit, it's wet there.

True, but at least they're cheap

I tried that once on another vehicle and ended up with a stuck bolt. It sheared off next time I was in there. I'd recommend some RTV around the head of the bolt, but not on the threads, and not in the hole.

Success!

Looks like the new gasket/seal did the trick

It was much tighter and I had to push and thread it on the bolt all the way before reinstalling the drain plug.

Thanks!
