Same '01 Trooper LS. Has developed a leak that seems to be coming from a small pan located on the bottom of the oil pan. I have looked high and low for a gasket to fit this application, even the My Isuzu Parts.com website. That site doesn't even show a gasket made for the oil pan and no reference at the local auto stores. Anyone know about this? Form-a-gasket the only hope?Edited by: sicilian68
