Doug ... I had the same problem with my pan bolts .... they were too long , but short enough that when they were installed along with a lock washer , they gave the impression of being tight and the pan being secure . However , that was because they had bottomed out ...
oil pan leaked like the devil and took a while to find out why . I kept retorqueing the bolts and it didn`t help . I have to pull my pan now to change out the gasket and am real interested to see if the Mr Gasket bolts can be made to work , otherwise , I`ll use studs with blue Locktite .
An alternative is to shorten all the bolts ... but that would be a real pita .
