UPR Drain Plug Leaking?

[I Bleed Ford Blue]

I had the new style that has a valve that you have to open.

Did this drip happen over and over after cleaning. I have gone on 4 trips and had the same drip come back only after driving. Car has sat for 2 days now with no oil to be found

After the car's initial oil change, I cleaned the belly pan area, twice. The first time, it was just the obvious part, near the edge underneath the plug. Like you, I thought it was more the plug or a close splash I missed. I thought that was that. But the drip was there, again.

The second time, I was confident the plug was not the issue, because the plug itself was dry to the touch. It was the belly pan and a small portion of the oil pan that was damp or wet this second instance.

I got the car up on the Race Ramps and spent a proper amount of time on it. That's when I realized the extent of the splash. Things cleaned up quickly with a T-shirt and a few good passes and double-checks. I could snake the shirt in enough where I did not remove the belly pan.

With the plug in now, I still tuck a t-shirt in the gap during an oil change. When the drain plug is finally removed, what oil that does come out naturally seeks that gap towards the belly pan.

As others have mentioned, along with the splash, O-rings on the plug or the race in the pan itself might have a small amount of garbage preventing a good seat. And certainly, the O-ring/s might have gotten nicked and need replacing.

I also keep the OEM plug. Just in-case.

Whatever it is, hope it's an easy find and quick job.

Edit: that you're seeing it only after a drive, that seems to be a good thing. The aero and gravity of moving the car is pushing whatever is hiding, out. That was my experience. I'd think if it was the plug, it either feel loose or drip all the time.

I just stick with the factory plastic plugs. just $10 every oil change brand new.

Same. I understand why people want to get a reusable one, but the nylon factory one isn't weak or anything. Plus, since it's the same material as the pan, you don't have to worry about different thermal expansion/contraction rates. I suspect that's what's going on in some of these cases, it's only leaking when there's a certain temperature differential.

So I did an oil change last weekend on my 21 Mach 1, its my 6th one and I do them all laying on my garage floor.
This time I noticed a slight leak on my garage floor every time I go for a drive. I clean it up and find another one on next drive. (doesn't leak unless I go for drive.) I Spilt a lot of oil when removing filter so I thought that may be it trickling it's way out but now I don't think so. I lifted the car up again and looked by the filter, no leak. Seems to be dripping off the edge of the plastic skid plate which is directly under the oil pan plug. See Pic. No drip from plug but it's on plastic. Is it possible the UPR drain plug O-ring is bad or something and slight amount of oil is coming out after pressure builds up from a drive. I've had this plug in since my first oil change. I'm at the point where I'm just going to go to my dealer and grab the factory one and dump all the 10 quartz into a very cleaned oil pan and then refill with same oil but what a pain in the ass!
Anyone experience this with a Bad plug?

Thinking Factory replacement is a good first step & hopefully for you the fix.

I have this version of the UPR plug.

Done a few oil changes and have not had any problems with the plug.

I have however experienced the drip you're concerned of.

My first oil change was probably like most peoples': attempting to control the rush of hot oil escaping the engine. I had a drip similar to yours, but when I checked the plug, it seemed secure. I then noticed some oil in the general area of the oil filter, on the belly pan.

After fishing a rag in-between the belly pan and the engine, I found the source of my leak: oil that had splashed up onto the belly pan, and was now drifting to the end, the edge. At first glance, it appeared to be a leaking filter or a plug. But it wasn't.

I cleaned as much of the belly pan without removing it and have not had any issues since. As others have done, I now stuff rags along that edge. Cutting a half-moon below the plug sounds like a great idea.

Replacing the O-rings over time is something I need to refresh myself on.

I have this one, no issues with mine yet, I've done two oil changes with it.

Hrm, so the OEM part is supposed to be replaced each oil change, or are people swapping it for peace of mind?

I personally don’t think you need to change it every oil change, I think every two or three oil changes is fine. There are a lot of aftermarket ones available, I choose to buy OEM.

They're replacing it because OCD.

I went with this idea, not believing the toss & replace, with oil changes. Not knowing, bought a spare 2020, still sitting in the bag, so as of now not necessary. This year I hung it on the Christmas tree.

If I recall, you have a set of ramps? If so, get the front end up on ramps and see if you get any oil runoff. If there’s anything still sitting in the belly pan, it will run off when you get the car on an incline. Since the leaking only happens when you drive, my guess is there’s still some oil hanging around from when it spilled and driving around gets the residual moving around . As others have said, it can hang around for what seems like forever.

If you get the GT500 oil pan, you get a metal drain plug and will save yourself $20 with every oil change.

And how much is the 500 pan? Seems like stepping over a 10 dollar bill to save a penny.

EDIT: LMR sells the 500 pan kit for 915 bucks, so at 10 bucks a pop for the ford plastic drain plug, you would have to change the oil 92 times to recoup the price of the pan. Seems like a waste of time and money to me.

This isn't even a "peace of mind/cheap insurance" part. It's just unnecessary. There's no moving parts. Nothing to break or fail or wear out or any of that. It just is. I'm actually scared to buy a new one. My stock one and the pan are family. They grew up together. Moulded as one. Scared my oil pan won't take to a new one and accept it as family. He'll get pissed off I threw his perfectly good little buddy away!

I'm pretty sure people are installing a new plug every time because if you're the type that must follow the manual to the letter, some have misinterpreted the word "replace". The intent of the manual is to replace the drain plug back in the hole; e.g. reinstall. Not discard and replace with a new one. Haven't read it in a while, but I don't recall the words "one time use" or "discard" associated with the drain plug, which is the typical language Ford uses in the manual for something they want, well, used one time.

I've checked the manual, there's nothing in there about changing/replacing the oil pan plug.

Nothing.

You can't debate with obsessives. Their life revolves around finding things to obsess about. That's it. They'll never stop.
