I've heard that If you go to a synthetic on an old engine, you may get a 
lot of leaks. The detergent effect of the synthetic will clean out the gunk 
filling any little cavities and imperfections in the gasket; and this may not 
leave enough gasket to hold the pressure. 
    Then you were on borrowed time. It was time to replace the gasket anyway. 
The gunk is not a gasket, just a false sense of security!
