M14.1-1.5 x 15mm Oversize Piggyback Oil Drain Plug, Stainless Steel Self Tapping Oil Pan Thread Repair Kit

My ls1 cx racing oil pan drain hole got stripped after 2years and kept leaking oil. Found this quick easy fix plug, installed it and it fixed my issue no more leaks. Totally worth it.!

The threaded part broke with very little torque. I didn't even get it tight and it broke the threaded end off at the nut. I would not recommend this product as it is very weak and thin where the threads are.

Claims it's oversized. Not sure what part is oversized. I had a stripped out plug. Figured oversize plug would solve this repair. NOPE, new plug size size same as original. Had to do modification to make it work.

The design of these piggy-back drain plugs are simply genius, and worked flawlessly to repair a Yamaha TT-R125 with a stripped oil drain plug hole. Added high-temp RTV to the washer, snugged it down and away I went. No more leak! The one-day shipping through this seller was a huge bonus as well.

An economical repair when you unexpectantly find some garage gorilla use their "calibrated elbow" and over-torqued/stripped the oil drain plug in a BMW 4,4 ltr aluminum oil pan.
