The last mechanic I went to torqued these to hell…what are the chances he also tightened my spark plugs this much?
Never again…my other mechanic never overtorqued things this much.

Had an oil drain plug bolt overtightened so hard once I stripped that sucker getting it out so bad I had to buy a replacement. The cost of just quick taking it in because I didn’t have the time cost me an extra $20. Never again.
what are you even supposed to do in this case? Lots of WD-40 and tap with a hammer lightly?
There are two possible solutions for fucked-up oil drainplug threads:
A) Drill the hole out slightly larger, tap new threads into it, and install a slightly larger drain plug.
B) Replace the oil pan entirely.
Option A isn’t always possible, especially if the oil pan is curvy, very thin, or made of plastic. And either option requires removing the drain pan from the vehicle and reinstalling one with a new gasket. (You don’t want metal shavings getting into the engine when you’re drilling and tapping.)
You can drill and tap or helicoil in place, just flush the pan with a liter of oil.
What the hell are filters for then? Rust proofing the frame and engine bay?
If you end up rounding off the head there are a few options. They make special sockets that can grab onto a rounded off bolt. You can try to hammer on a slightly smaller socket. You could drill the head off of the bolt and use an extractor to pull the remnants out, but you risk breaking off the extractor and then you’re in a real pickle. You could also weld a nut onto the bolt, but not recommended with a full oil pan. You can also take a hammer and chisel and try to get the bolt to turn using it at an angle, not recommended if you have an aluminum oil pan. You could also just buy an oil extractor and pull the oil through the dipstick tube.
I don’t have any of these issues because I change the oil in all my cars and can read a service manual.
In my case I had rounded off the bolt head in a few spots with an open ended wrench after a few tries not realizing it was going to be stubborn. Had a hard time getting the correct sized close ended wrench on with the warped sides. Went up a size by switching to metric and getting a decently good grip. That stripped it further, but warped the head even more so I was able to get the right sized closed wrench on it with a few “gentle” taps of a hammer. It juuuuuuust barely came off. The head was mutilated to hell.
I’ve seen people use a grinder to grind down the sides of the head and use a smaller wrench to try again. Or cut a plus in the head and try a screwdriver. But that’s assuming the head hasn’t popped off yet.
Impact driver, but the bolt could snap.
Actual oil pan bolt torque is lower than people think, but a fresh crush washer should be used every time.
Now Fords use plastic oil pans, which should be fun with those gorillas.
Thank got almost nothing is plastic in this car.
