I was short one or two doing a major repair so I bought a couple grade 5 or better 6mm bolts at a hardware store.

The short bolts were the oil sensor is.

Use real OEM to figure out the length use washers to simulate the proper diameter of the original bolt.

It's very common for people to over torque a 6mm bolt use a torque wrench. Pre tighten then all then torque them skipping over each. Over torque and risk stretching the bolt and it won't hold the proper force or crimp the seal and it leaks between the bolts.



Make sure the pan is flat as possible before reinstalling in case that was the cause of the leak.

I wouldn't be opposed to using permatex especially if the pan has ripples
