Did you torque the bolts in the correct sequence and in at least two steps?

Nope, a crappy $40 one! Any recommendations for a good one?

I'm pretty sure I did, just didn't torque them properly. Fortunately the car isn't leaking oil quickly, just a super slow drip after a drive. I did the pan swap back in April and when I checked the oil yesterday, the dipstick was at the top of the upper most X. The car is on jacks now, waiting on me to get parts in. Does hardtopguy or h and a honda sell replacement bolts?

I have $20 torque wrenches, and all of tjem are surprisingly accurate.

Its on you to make sure to stop turning when the wrench clicks. Also, if you initially tighten a fastener not using the torque wrench, and accidentally overtorque it, then put the torque wrench on it it will click. Don't assume this means its correctly torqued. Wrench has to move before it clicks or your torque is wrong.

Chances are very high that a left handed bit will have the broken bolt out in under 10 seconds.

This should be your first move.

That's what I'm going to try first. I've ordered the drill bits and a proper torque wrench. I'll be sure to report back before I drop the pan (if I need to, that is).

If the LH bit doesn't work:

Remove the pan. If there's enough of the bolt still sticking out, VERY carefully use a Dremel and slim disk to cut a small slit in it. Use a flat head to turn it out.

You may well struggle to get a drill in there, due to being so close to the side of the sump...

I had to drop the pan as I couldn't get a good angle with the drill bit. Here's where I am now:

And here are the left hand drill bits I bought:

When I put the pan back on, should I put the honda gasket material in the bolt holes in addition to forming the gasket? I don't remember if I did this last time, and that may have one of the problems.

Got the broken bolt tip out and I'll be putting on the pan within the next few days. Thanks to all for your tips and suggestions!
