well it seems to be a bad week for me with the slid pins on my caliper and now my oil plug. I changed the oil in my truck from 15w-40 to the t-6 sythentic 5w-40. everything went good until i took it for a test drive and i get back let it sit for a bit. then i notice a oil spot under the truck. I take a look and i see oil slowly dripping from the drain plug. after about 8 hours it forms a puddle the size of a baseball. So i bought a new washer for the drain plug did a quick swap and same problem its still dripping. The bolt it snugged up and the washer is new any ideas of why it would still be dripping. Bolt was brand new from the oil change prior. and it never leaked with the 15W-40. any ideas 02 f-50

 

Did it by chance have a nylon washer before and a copper washer now? Mine would get just enough oil dripping to collect and hang on the drain bolt with a copper washer, but never with a nylon type.

 

Copper washer was on there originally and i replaced it with a copper washer same size.

 

Order a Fumoto Oil Drain Valve. I don't exactly know why, but it stopped my leak and many others have had it do the same thing for them. Plus changing your oil will be so much easier from now on!

Riffraff Diesel: Fumoto Quick Drain Valve

 

I will have to order that valve and give it a try for that price. what can i do in the mean time to stop it from leaking. maybe put some sealant of some sort around it lightly to help stop the leak. I will be heading up north in a couple days for hunting. I dont like heading up there with a leakfrom the drain plug.

 

The only thing I can suggest is to go to the parts store and try to get a nylon or fiber washer like was mentioned above. It may help. I don't recall if the Fumoto has pipe threads, or what, but I do recall it being a more tight fit, for lack of better words.

If you have a shop vac, I have read that you can use it at the oil filler tube to apply some suction pressure and give you a second to remove the plug and swap the washer, etc, without losing too much oil. Disclaimer, I have never tried this, never had to, but it should work.

 

ill stop at the parts store tomorrow and see if i can get something. if i remember right my 00 f-250 gasser had a nylon type washer and never had problems.

 

It will work, I've done this to change the valve on the bottom of a 275 gallon fuel oil tank. My only suggestion is to not completely tape the hose to the fill tube. If you do, it will suck so much air through the drain plug that it'll probably make the oil foamy. Leave a little space open for it to suck some air.

 

I use the washer with the black seal from an assortment from A Z, that one has been the one that works for me every time

 

I'm gona try that type washer next time Digger. I'm done paying ten pucks for a new crush washer at each oil change.

 

the Fumoto Oil Drain Valve works wonders.

 

Getting one before my next change....for sure !

 

You guys change it each time? I've been using the same copper washer for the last 85k with no leaks (knock on wood).

 

my washer lasted 140k then i would drip.

 

Don't know, the PO, had **** service records, all from the original dealer...the plug had a washer with a black gasket attached,so I found one just like it, so far so good
