Briggs Intek V-Twin(s) Blowing Sump Gaskets....
Engine: Briggs Intek V-Twin 26 hp 446777-0244-E1
I am having a problem with blowing out sump gaskets on this model engine. Twice it has happened on two different engines:
1. My original factory 446777, purchased in 2004, developed the sump gasket leak after about 8 years use. I replaced that gasket using RTV Blue as a sealer and it does not leak (so far).
2. I rebuilt a second 446777 for another tractor, about two years ago. This engine developed the exact same leak last summer. The picture below shows this engine that I just now disassembled. The picture shows the damaged gasket exactly as it appeared when I opened the sump.
In both engines the leak was in exactly the same place (directly below #2 cylinder). The original 2002 factory engine did not have any sealer on the gasket (as I used on both gaskets I replaced), but it did fail in exactly the same place.
