Transmission Pan Drain Plug + Undercarriage Coating

Improvise! How about a piece of a wire coat hanger with a small bend at the end. Could even use that hammer to flatten the end of it if you need to.

I bet that woulda saved me some time. Ended up getting it off with the needle nose after a bit more prying. I scratched the surface of the tranny where that o-ring sits (barely), I hope that's not a big deal. Went to install my drain plug and realized I don't have a 1/2" drill bit. So it goes, I guess. I'll stop by the hardware store tomorrow and will hopefully get this finished up!
 
Under coat it with motor oil?

First question would be why oil? Its not going to stay it will wash off first rain storm. Oilly things dont make it easy to work on. How will you tell when it is leaking where it is leaking from ? :D

Paint and keep it clean then paint it again when the paint wear off.

It's not just the first rain storm, it sticks around for a while. I can definitely tell which sections of my vehicles have been coated in oil or diesel. They're the ones where bolts actually come out without a torch. :wink1:

As for the why, I've always assumed that oil is just cheap. Especially used oil.

I agree that oil does make identifying leaks harder.
 
Campfire is right about the only areas of our salt belt trucks that the bolts will actually unscrew ,are the areas where the engine,trans,or diff leaked on them--its usually the only areas no floor or fender rot happens too..

Used oil from a diesel as I noted earlier has quite a bit of soot in it and that will form a glaze when some dust & dirt gets on it during normal driving..old timers here always thinned their drain oil with some mineral spirits and sprayed it back under their vehicles on the undercarriage and went for a drive down a rural gravel or dirt road to make a thick coating,that served two purposes--one,it got rid of the used oil with no fees or hassles,and two,their vehicles lasted years longer than those never "oiled"...

Some guys claim hydraulic oil penetrates the pores of the metal better and resists washing off longer,I myself never had any to try--but ATF is hydraulic fluid basically,and the area where one of my plow's hoses weeped onto the front inner fender is the only part of it that isn't swiss cheese..Linseed oil will eventually "harden" and wont wash off easily and seems to protect against rust pretty good,if your looking for a more environmentally friendly rust preventative.

I do not like rubberized undercoating much,it lets rust form under it and you wont notice it until its a hole or blister that you can poke a finger thru..
 
So far, my only tools to get that o-ring out are a hammer, a small (micro) flathead, and needle nose pliers. I'm not getting very far...

Been oil undercoating for years. Bar and chain oil works well. It is more tacky then motor oil. Tried used oil, made me Ill spraying it . this year I used fluid film. Much less messy to work with but kind of pricey. Time will tell. Does it work? Yes! I have a 08 f-350 that looks almost like new underneath. And the wife's 04 Toyota with 280000 miles is still in exceptional shape.
