My pan (89' Kick) was glued on with Silicone,
if the pan got put back on this way, I'd say
the pan, tho even with a gasket it can still leak.
I rebuilt my engine at 250,000 miles, never had
a rear main leak, but the pan leaked, no real leaks
since the rebuild, tho the trans likes to spot the drive.
Old Suzuki's don't leak, they just mark their territory
