I had a rear main seal and a valve cover leak of one cup per week,Chevy dealer wanted $1,500 to fix.Put in an 8oz. bottle of Blue Devil rear main seal stop leak and it now leaks 2 drops per week.Called up the company as the product is guaranteed to stop all gasket, leaks , they refunded $16.00 that i paid Auto Zone.
2 drops! I woulda hung up on you
