Oil Sump Nut Threaded

Hi All,

Hopefully some one can guide me in the right direction here on how to fix this problem.

I have performed an oil change on the car and the sump nut was spinning in the sump. I managed to replace the sump nut and there is no leaks coming out of the sump but I have a strange feeling that when I take it out again it wont stay in next time so I need any advice so I can change this nut out asap!!!!

will I need to have the sump re tapped or is there another option???

The nut still has threads on it as well.

Thanks folks for any help

Do you mean the oil sump bolt?

If you've stripped the threads, it's probably the softer aluminum oil pan threads that have stripped and not the stronger steel bolt. The way to fix this is going to be with a Helicoil, Timesert, or other thread replacement product. Make sure to get a good brand thread repair/replacement kit, and follow the instructions to the dot. If you do, you'll end up with more durable threads than before. If you don't, you'll be left with an even larger stripped hole.

Also, don't mind Steven747. He's mentally challenged.
