Grand-dad was an old-school mechanic--not a parts-swapper--and he had a dim view of products he called "Mechanic-in-a-can." When I would ask about this or that product, his response was ALWAYS, "Why don't you take the time to actually fix it right?"

Buzzman72...void where prohibited, your mileage may vary, objects in mirror may be closer than they appear, and alcohol may intensify any side effects.

First, I would make sure the PCV system isn't plugged up or capped off because the excess pressure in the crankcase forces the seals so tight that they burn out, causing leaks.

And people accidentally/intentionally lug them off too with aftermarket covers with no vents. Happened to my 454 I got. I had to pop a cover off and drill a hole just so I could add oil without squirting it down the dipstick tube!

check the oil pan bolts...mine developed a small leak last year and I also thought it was the rear main, I crawled under there with a flash light and gave it a good inspection and the seal area was dry as a bone but I did notice a drop of oil hanging off the oil pan bolts in the back so I checked those and walah they were loose, tightened them up and no more leak!
