Ran into this while doing an oil change, why is this like this? Why is there a chunk of thread missing? Vehicle is a 2019 Buick Cascada. Based on the look of things, At one point before it came to me the threads got cross-threaded or stripped, there was an attempt to retap and rethread the hole. There was a HeliCoil installed, And it came out while I was removing the drain plug.
What threads? Am I missing something here cause I see that oil pan threads are no longer there…
If this is a shit post, well done.
Yeah, the striped threads are what had me looking closer than usual, but not related to the question I had. I was more curious if that cause Cut away section was factory or part of the thread repair that some one attempted before I got it
That’s a factory cut due to the pan being lower than the hole for drainage.
