Ok, why is something that is so simple have to be so hard? Have I just become a test subject to see how far a person can be pushed before breaking? If so, I suggest that all whom are involved in this devious test quickly dive behind a well fortified barrier, as I am just about ready to blow!!!

Differential fluid change = An easy, dirty job, necessary, no parts needed, and completed in a very short time frame. Even I can do that!!

Yah, right!! The hex head of the diffential drain plug decided to end it's long relationship with the threaded body, that up until now, had been a blissful union made in heaven. It was a painful separation that indicated flaws had been present in their relationship from the very beginning. Now that their separation is known to be permanent, I seek a replacement that is bonded tightly enough together to ensure that they will be together for the remainder of all time.

I got the plug out, but now I need something to put back in!! I can't find a parts diagram that shows this plug. Neither can the Lamborghini dealer. Does anyone have a part number for the differential drain plug that is located on the bottom of the differential/oil sump casting that drains the differential fluid?

The plug measures out to be a 22 millimeter diameter X 1.5 pitch tapered thread. Can't seem to find a generic plug from anyone, or a part # from Lamborghini for an original replacement. Can anyone help out here, either with a source, part #. or a good used one??

Thanks all!!!!!

Have you thought about using a heli-coil insert and switching to a more common drain plug?

Yes, but I would prefer to keep this thread/plug original. Give me twenty minutes and a few tools anfd the problem is solved. But it is no longer original, "it is modified" and so forth. That just becomes a future problem.

12097,

Forgot to include a very big thank you four thoughts in the previous reply. Take care and be well!!!

Your very welcome.

Is it just the drain plug that is stripped or both the threads in the drain hole and the plug?

If it's just the plug, you could take a metric thread chaser (just to clean out the threads in the hole) and then install an original style drain plug.

I would also be tempted to use an anti-seize compound on the threads to make sure future removal efforts go more smoothly.

Good luck.

Do keep in mind whey you guys start talking about heli-coils and things like that, that you are looking at a PIPE thread. A pipe thread is tapered not straight.
I have a sump not on an engine, I will pull the plug and get a size for you.
