Good evening everyone,
I guess I drew the short straw today.
My attempt to install the No Spill was not successful.
After slowly removing the bolt and working it back and forth so the threads would not get damaged It got to a point where i needed the ratchet again then it became easy to remove the original bolt.
The No Spill went on by hand just fine using my fingers. Then it got to the point where I needed the ratchet. Again slowly working it back and forth. Once the washer was up against the oil pan I put the torque wrench on but it would not tighten to fifty lbs and oil was oozing out.
I finally decided to remove it and reinstall the original bolt since it was longer.
The original bolt went back on but i didn't even torque it to 50lbs because of what may happen.
I now have seapage coming from the drain plug.
Inspection of the No Spill bolt had some aluminum on the threads.
I guess I'll be getting a new oil pan soon.
I don't think you need a new oil pan. Cummins has a fix, and I am sure Helicoil does too.
You may need some machine shop time, too.
Na you can drill and tap it and you will be fine. If you don't want to use the Cummins fix there is a thread that Wyatt started that is real good on this repair. I will get IT department head to see if she can find it and link it here.

50 lbs torque seems high for a drain plug in an aluminum pan with not that deep threads. I think it's about 44 lbs on your pan and knowing the history of the alu pans, less might be best. 50 sounds right for a steel pan.

I recently did the Cummins fix, and did a write-up of the procedure. Others have described it as well, but I hoped to give all of the information in a single post.
M-11 Oil Pan Threads (https://www.foreforums.com/index.php?topic=42391.msg424577#msg424577)
1 inch by 18 tpi just seems like the threads are not very robust for something getting regularly removed and reinstalled. Wyatt makes a good point that you can go just a pinch bigger with less threads per inch and have a good repair.

My No-Spill instructions stated 30 foot-pounds torque, not 50.
Here's mine
1-18 UNS*** reads in English, one inch major diameter of the male thread, eighteen threads per inch Unified Special.
UNC, Unified Coarse* would be 8 threads per inch and and UNF Unified Fine* would be 12 threads per inch in that diameter.
UNEF Unified Extra Fine** would be 20 threads per inch in that diameter.
So ain't yours special!
*Standard off the shelf.
**Weird but standard off the shelf in a specialty store.
*** Buy it from us.
Well,
Will be going to FOT to get an oil pan installed with the Cummins factory fix.
This is a used pan that has been sent to a local machine shop and has been repaired that Foretravel keeps on hand. They will keep my pan and repair it so it's available for the next customer.
