it's like a spray rubber sealant.. yo will actually seal the pan to the block from the outside.
the trick is to get things clean enough first.
Id start with a pressure washer or at least a trip to a self car wash.
a bit of scrubbing and brushing may be needed.
finish with a healthy dose of brake cleaner..
spray the sealer...
the oil pan shouldn't have pressure pushing oil out..
let the stuff dry before
I have used the stuff to fix a leaking valve cover that had a broken bolt.
and I also sealed a leaking intake manifold.. way cheaper and much easier than trying to get the pan out...
and pan gaskets are very hard to clean.. they stick to the block and the pan and will rip... also the front seal and the rear seal will probably fall apart if you try to drop the pan..
If you want to drop the pan.. I would suggest only dropping it about a 1/4 of an inch and using a rtv or silicone to fix the leak.
and dont remove the bolts just loosen them.. I think a few have to be removed..
