Oil Pan Drain Plug Stripped

I was changing the oil today on my 98 5.4 4x4 and discovered when I went to tighten the plug it got to a point and just started turning with little resistance.
Any suggestions on what to do?

Depending on how bad it is you can get a thread repair kit (like helicoil) and put a new thread set up in place. If the threads are to bad for the insert, then get a drill bit, tap and new oversized drain plug and put new threads in the pan. Thats the easiest and cheapist way to go.

Other option is to replace the pan...but that will be lots of fun since the motor has to jacked up to remove the pan.

Only thing I see about the heli-ccoil fix is how much of the coil goes thru on the inside of the pan. Might trap a lot of sludge, keep it from flowing out

I hope my point came across clearly enough. Lol.

What I mean to say is that, if the thread on the pan is only like 2-3 threads deep and you use a heli coil like 10 threads deep, it would be raised on the inside of the pan.

But, then again, if it might not be that big of a deal. IDK. Lol.

You can sometimes cut down the size of the helicoil (make sure you cut the right side off first) or they also have diffent length coils as well.

Not to sound crazy here, but are you sure the pan is stripped and not the plug?

Yep, 9 times out of 10 that is what happens. Go get yourself a new plug.

Boat Plug

It it is the pan, you might try one of those bung-hole plugs that they use in watercraft to plug the rear drain holes. Not sure just how well they would stnd up to hot oil but it may be worth a try.

Do not use one of those. About 10 years ago some grease monkey lube shop screwed up the threads on my dads old F150 and used something similar to that. I didnt know until 2 months later when I took truck for inspection and saw it. It was leaking. Anything with a rubber seal will fail due to the oil. Had to have the oil pan replaced because the monkeys screwed it up bad (later found out it was a bunch of kids there and they used an impact to put drain plugs back in)

Fix it the right way, either new plug, helicoil or new pan. I dont think an engine is worht the risk of loosing the oil.

on my 02' f150 i stripped the plug of mine many times and the threads were shot on the plug. Only some of the threads on the plug were messed up so i put it back in there. A few oil changes later everything went fine then went to tighten it down and i noticed with the wrench that the oil plug was moving in the threads, even though it was tightened down. Because I'm notorious for over tightening things i had cracked the threads but not too bad.

I would suggest if you have the same problem to get a Fumoto Qwikvalve. it's a drain plug with a valve on it so all you have to do is push and open a small lever to drain the oil quickly. It replaces the plug and the next time you change oil you put it on like you would a drain plug and close the valve. Find it at qwikvalve.com. I've had it for about 6 months my brother a few years on his SD and no leaks or worries about stripping a plug or pan, just hope your pan isn't stripped.

I took it to a friend and we put it up on the lift. The plug was stripped out not the pan, so all i did was put a new plug in and off i went.

There is also a oversize plug made with a smaller plug in the center, so once the plug is installed, you leave it and use the smaller one to drain the oil.

Another way would be to braze the stripped hole some, and then retap it in the correct thread size. Of course flushing all the loose shavings when you are done.
