Factory pan bolts, torqued to the right spec. I used the 3M yellow glue and let set a day till dry, No leaks. I think what ever you use for glue make sure it's set up before putting oil on it. Had a Max Wedge long ago, some pan bolts would be missing after each race, so I'd really tighten them, same thing again. Then on a whim I torqued to what the manual said and they never losened up again.
