    oil pan bolt head snapped off

    Being while taking a look at my rear main seal condition I ended up snapping the back oil pan bolt head off..............I am at a complete loss of how to fix this. Because it's at the back it also holds the rear main seal tightened in and it drips very little oil, but it's dripping oil nonetheless. Any suggestions, it's not a super serious issue but I want to fix it because i'm anal like that. Where the head snapped makes the rest of the bolt not flush with where it fastens, so a "easy out"(even though they barely work) would be difficult. Even If I try to drill it out, how can I keep it straight enough to get all the way through the bolt. Idk i'm baffled.

    Also, where can I obtain new/used oil pan bolts incase I snap another one. I checked RealOEM for a part number but couldn't come up for one....Thanks guys.

          Use an engine support bar, drop the subframe and just take the oil pan off. Once the pan is off, you can get it out with a set of vice grips. It's a lot of work but the least risky option.

          If that seems like too much effort, you may be able to get it with an easy out. Use a pinhole punch and punch the end of the bolt. Follow up with a center punch and then attempt to drill a small pilot hole for the easy out. You are probably going to have to grind down the punches to fit in the counterbore. However, this approach might be impossible given the clearance....

              I wouldn't be able to turn it enough times to unthread it from the block. :( I actually tried that.

              Sounds like a good idea, i'll do my best to get it on a lift at my dealership do get a better look but idk. The location just pisses me off, cause any other oil pan bolt I'm sure would not be as difficult or awkward. Thanks for the idea
