Pilot drain plug question?

[Geniousc]

I usually change my own oil in my 2005 Pilot. The first oil change I was surprised to find that Honda was using a 11/16 SAE drain plug as opposed to a metric one. I couldn't find time to do the 4th OC so I took it to the Firestone store in the neighborhood. The next time I change the oil I found the head of the drain plug all but destroyed from the butcher mechanic attemping to force a 17MM wrench on to the 11/16 drain plug. After getting it out I take it back to Firestone to show what the mechanic had done to my plug. Long story short I lost the battle, they insisted it was 17MM and at the time I couldn't prove otherwise. I get the plug back home and being a machinest type I measure the plug with a micrometer, it measures .6875, within a thousandth or 2, I don't tremember. Exactly the dimensions for 11/16, my plug is without a doubt 11/16. My question is, is this normal or do I have an odd ball plug? I should pop for a new one because this one is chewed up pretty badly. Any comments on drain plug size? What size is yours?

17mm here. I just assumed everything on the Pilot is metric. I can't see Honda having some metric and some SAE fittings

17mm also. And is the plug you have on there 11/16ths head and metric threads? This wouldn't make any sense.

Something is fishy. My guess is that your car had the drain plug replaced with a non-standard part at some point before you got it.

I know what you guys are saying but I bought the car in the wrapper so to speak, they had to put it through delivery prep. If the plug was not installed I would take a picture of it with the wrench on it. I'm dead sure of my findings, it measures 11/16 across the flats and my 30 year old 11/16 Craftsman wrench fits to perfection. The 17mm makes and did make a mess out of the plug. I don't get it either, it doesn't make sense, when I did the first oil change, the first wrench I grabbed was the 15MM and 17MM and they didn't fit after working at it for a couple minutes. After fiddling I finally tried SAE wrenches and struck gold. I am very competent at threading and making my own parts on an engine lathe from hex stock, it's not like it's something I'm not familiar with. I've been changing oil for a long time. So everyone's plug is 17MM is what I am reading here.

Changed my oil this afternoon and it's still 17MM.

I've been using Fumoto drain valves for the last several years and they sure make oil changes easier, click on their site to check 'em out.

Maybe you have a Vue engine.

You know, I hadn't thought of that one. You just might have something there. I was wondering why I had to put in "R" to go forward.

I went down and checked mine (it is out because of my fumoto drain valve).

It is indeed a 17 mm. Something is bizarre about yours being different.............

I also enthusiastically endorse Fumoto drain valves.

I have it on both Hondas, going on the Miata next oil change. They make life so easy.

Now just for that pesky Miata filter! And I thought the Pilot's was messy!

I'll also recommend the Fumoto valve.

If you want my OEM drain plug PM me your address. I'll be happy to send it your way. I pulled it at my first oil change, 65kmis ago.

Thanks for the great offer, I sent you a pm. There are some great people out there.
