How important is torquing the pan bolts? I dont have a wrench that goes below 5ft/lbs.
Lucky you, it's much easier that way! Sometimes I'll use a fine scotchbrite pan to remove ALL old gasket, and cleaning with alcohol is good too.

The biggest mistake people make when installing the pan (more so on the OEM pan) is overtightening the bolts. With our pan you're fine with 5ft/lbs, that's what we recommend. On an OEM pan once you exceed 5ft/lbs the area between each bolt actually begins to lift, potentially leading to a leak. What's important to remember is that the pan bolts don't do much more than hold the pan in place until the gasket/adheasive cures. Once the gasket cures the pan isn't going anywhere.
