My oil pan drain plug is about a 1/4 turn away from being stripped out. I have a slight leak and want to address this ASAP. What size plug comes stock and what size can I go to for an oversized plug? Any other thoughts, ideas, or suggestion in regards to this matter? THANKS!

EARL!

 

Did you use a new washer?

I put a new washer on every other oil change and have had no leak problems..

Just my .02 pennies worth

 

No, I did not use a new washer, not sure that it would make a difference since the hole in the pan seems to be closed to being stripped out from the previous owner being a bit too over zealous with the tightening on the drain plug.

 

Maybe double up on the copper washers would be my suggestion. Maybe get yourself a Fumoto drain valve from Clay, this way you tighten it down and its done.

 

Has anybody actually put an oversized drain plug in their oil pan?

 

If it is really fubard you can use one of these:

OIL DRAIN PLUG by Motormite - Part 5707897 - Advance Auto Parts

 

Second the fumoto valve like Mike said then no more removing the plug, & easy oil changes.

 

I would like to do the fumoto but I am worried since the threads in the pan are not good.

 

Bumping this back to the top. I know that this is old, but does any ideas or suggestions? Thanks!

 

I would find a Fomoto valve that was a slightly larger thread size and re-tap the plug to that size and be done with it.

 

I've done quite a few oversize plugs. I am unsure of the stock size of the drain plug on these trucks. The oversize plug will cut new threads as it is tightened in the pan.

 

Did not see it mentioned, but important to know: replacing the oil pan requires removing the engine.


Fumoto FTW!

 

I think I'd start with a new, standard size drain plug. It's far more often the threads on the plug that are hosed than the threads in the pan. Most drain plugs are softer than the threaded insert in the pan and therefore, get buggered up first.

 

What he said. Try a new original plug first. I had a pesky drip with original, but went with Fumoto for convenience. Problem solved.

 

if it was on its last leg when the thread started, how did you manage to make it 6 yrs later without doing anything to it? Has truck been parked? Has the oil not been changed in 6 yrs? If youve been driving and changing oil all this time later, maybe its not as bad you think it is. But i recommend the fumoto, thats what i got, install it and be done with it....
