It doesn't leak

Works as designed. Some RTV sealants tend to leak even within short periods of time. I used this the same day I received it and it doesn't leak.

      Comments about Permatex Gear Oil RTV Sealant (3 oz):

      Put it on gasket then put gasket on differential cover (Ford manual recommends using both) and the gasket literally wouldn't budge after 5 minutes. Let sit for an hour after thumb-tightening differential cover on to differential, then torqued to specs. Waited 24 hours, filled up... no leaks after test driving. Seems great so far, only more miles will tell if it holds up. Somewhat difficult to squeeze out of tube... I mean I really had to squeeze hard, but it's the only one specifically made for differential gear oil.

      Installed on 2001 RWD differential cover over 15 months ago and still no leaks. Apply Permatex gasket maker to both sides of gasket.

              Hi Jerry, glad to assist you! This Permatex Gear Oil RTV Sealant (3 oz) (Part No. 81182) has been specially formulated to withstand the harsh gear oil environment found in many differentials and transfer cases that destroys normal RTV materials. This
              product can be used to seal cut gaskets. This material cures on exposure to moisture in the air to form a tough, flexible, silicone rubber gasket. The product resists aging, weathering and thermal cycling without hardening, shrinking or cracking.

          • Q:

            Why don't the "advisors" answer the question asked instead of just copying and pasting the text from the specifications for this product? I hadn't noticed it before but see it happening everywhere on the QandA for a large number of products on this website now.
