Oil Plug Difficulties

Jim in Western MI · Apr 23, 2014

This year proved more frustrating than ever just getting the engine oil drain plug out. ('48 8N) Flats are just worn and pipe wrench slips, the all-purpose tool doesn't. Anyone solved this? How about welding a BF grade 8 1" nut onto the square nut?

Check out tip # 65.

That works. But, you will need to braze it. The plug is cast.

Or just buy a new one.

And always use a gasket w/ Neversieze on it,

I have removed them by using a hammer and chisel on the outer edge of the plug being careful not to damage the base where the seal rides. You will need to get a new plug and gasket and as Bruce said put antisieze on the gasket to prevent it from sticking again as yours has.

Unless you have something I am missing a properly adjusted made in the USA pipe wrench should take it right off. You know righty tighty/lefty loosie? A guy can get that mixed up when stuff is upside down.

the hammer and chisel works if you have good aim.
as posted before, a big GOOD pipe wrench with a jack and block of wood holding it tight up works sometimes.
Grinding 'flats' on the chewed up plug so you can pound an impact socket on and bang away with an impact wrench works sometimes.

And, sometimes, you will just fail......
Had one that when I got annoyed and applied 'full fury' force to the pipe wrench, I broke the center right out of the plug.
Had to wedge a big hex sided chisel in the hole and then wrenched on that. Finally came out.
A spare plug on the shelf is always a good idea if you work on Fords.

if you don't mind non oem. the BF hex nut idea DOES work. lets you put a real wrench on it.

i did that on my 950..

tacked it on to get it out. then cleaned it up and put it on right.

will never be a problem again.

the original square profile was rounded and worn off.. and it looks like the PO was using achissle full time to take it off... not sure why they didn't just repalce it or do big nutz trick on it .

I had a stuck one recently. chisel and pipe wrench with jack to keep it from slipping down did nothing. A little heat did. Modest amount of it from a propane hand torch, directed mostly on the flange, and the plug came undone with only a little effort.

(Usual warnings about gasoline and fire)

I use a 1" to 3/4" socket reducer, my plug is all rounded off at the corners too. Just give it a good tap with a hammer and use the 3/4" side for a 3/4" combo wrench, when finnished I give another tap or two and the reducer falls off. Works perfect.
