MX-13 oil drain plug leaking

Never seen this before. Steel pan and plug on a 2015 T680. New copper washer last time the oil was changed.

Having a hard time digging up a torque spec for it, but I’ve tried giving it an extra 16th of a turn a couple times now. It’s definitely in there snug. Took 55 ft/lbs to even get it to budge with a torque wrench the first time I tried, so it definitely wasn’t loose, and I’ve cleaned off the bottom several times and retorqued to 60, 65, then 70 and the #### thing still leaks. What’s the fix here? A new drain plug? Double washers?

 

No they checked that when it was in for oil a couple weeks ago. That’s what I thought it was too at first. I can’t believe that copper washer ain’t seating flat and sealing it up, especially after cinching it up a couple times. I guess the only thing to do is change the oil myself next time and really have a hard look at that plug and mating surface. Some small detail a shop guy rushing through a PM would never notice must be what’s going on. I just don’t have a way to catch 10 gallons of oil is the problem. Otherwise it looks pretty easy.

 

Yep, all good ideas. Unfortunately I’ll have to live with it until it’s time to drain it again. I have a Fumoto drain valve on my 7.3 and it’s the bomb. The washer actually was replaced…the old one was a different color and maybe wasn’t even copper. It was like $2.50 for the new one. Pretty sure it isn’t cross-threaded. It had been leaking and making a huge mess for awhile the first time I noticed it prior to this last oil change, so it’s been out and re-installed since I’ve been driving it and no change. Swapping it out with a drain valve is a good idea next time it’s time to dump it.

 

I don’t have any way to catch 10 gallons all at once but I can ask the company shop guy if he has a way to help this next time. (The outside shop I took it to did a super half-*** PM anyway for what they charged.) Then install the EZ valve and maybe I’ll get lucky and that will fix it. I tried one of those on my 7.3 Ford’s oil pan and it actually did leak a tiny bit, so I switched to a brass Fumoto valve and it’s been on there for years without issue. Takes a little longer to drain but way but it does keep the mess to a minimum. Handy for grabbing oil samples too.
