Ford 5.0 Oil Drain Plug Design Change

[CCII]

I picked up some new drain plugs from my Ford dealer and they are a different design with two black o-rings instead of the single green one, a longer twist in connection, and now using a small socket to remove instead of a flat pliers. Both have the same base part number 6730 and he verified it in the Ford system by the VIN and by the Engine type (5.0 v8). So I have two questions: Has anyone used this revised design yet? And how do you replace the plastic drain plugs every time the oil is changed or do you reuse them?

I bought a new plug last year and it was the new style. I inspected the old one, looked fine, so I reused it. No leaks. It was a new to me car so I have no idea if it had been replaced before I bought it.

I'm using the new one, no issues and idk if the previous owner replaced the plug ever... so i did it for peace of mind. no issues and i like the double o ring design more

New plug a couple months ago, no issues , having a redesign to 2 O rings most likely can be reused . Idk if I will reuse . I have a few , so may use a new one every oil change.

The slot and hole appear to allow you to loosen it and drain the oil in a controlled fashion through a smaller hole before taking it all the way out and having a wall of hot oil gush out. I'm going to have to order one.

I've reused the old one many many times and perfected holding it half inserted to drain enough oil that once pulled out completely, it won't overflow the drain pain.

When I had the GT350 with the plastic oil pan and plug, I bought a new plug, put it on the shelf and re-used the old plug. I put 30 something thousand miles on it with frequent oil changes due to track use and always used the original plug. I think the design was slightly different than the plugs shown above, but possibly I just don't remember correctly.

Before I went to the UPR plug, I re-used my plug every time. I like the dual o ring though.

Wow that is a very observant comment from the photos. The drain hole and slot would be a nice feature to replace my skill at holding the old style plug in place to regulate the outflow while draining!

I buy 5 at a time, simply because the cost. For 10 bucks or so each I’ll just replace them every oil change

I noticed the change in drain plugs when I did my last oil change a month ago. I thought the dealer gave me the wrong plug so I reused the old one.

I don't understand though, why they would use different o-rings. I'm not talking about 1 vs 2 o-rings, but the change in color. As I understand it, the green o-rings are for higher temp for fuel/oil, while the black orings are for general use and not for high temp situations.

I also have a UPR dp, but I can't stand that they charge $20 for 2 o-rings, and they are black o-rings not the original brown o-ring.

They can make an o-ring any color you want, regardless of the base compound. It could be Ford saved a few pennies by using something off the shelf. I agree black is the most common color you see.

 

[T Fades]

Yeah they can make orings any color, but why not do it right and make orings the color they are designed for. That is the whole purpose of color coding orings, so one can differentiate what they are designed for.

I just used the new plug about a month ago. The design is supposed to allow you to remove it either by hand, with a hex wrench, or a slotted screwdriver. I like the double o ring design. I use them for three oil changes, and then replace it for the hell of it. Don’t know if it’s necessary, just figure why chance a leak.

From my opinion both the oil pan plug and the plastic pan are junk. With an engine as big as the 5.0 it should have a steel pan period. The plastic pan saves Ford money but in the long run the steel pan gets the nod. Ford realized their mistake and has switched back to the steel pan.
