I had an antfreeze leak in the front corner of my intake so i replaced intake gasket with felpro gasket put the rubber end gaskets on put all back together worked fine no leaks but after i drove it about 20-to 25 miles the front rubber gasket slipped out on the left side i pulled the intake the gasket was in two peices i again replaced the gasket to have it happy again .any suggestions i have a 1983 hurst olds with 307 any help wood be appreciated the rubber gaskets were in line on the rail till i drove it .

 

At this point I would throw away the rubber gaskets on the next try and use "the Right Stuff gasket maker" front and back.

 

thanks for the recomendation I was getting frustrated Ive done these on other cars never had happen before I'll get some and try it tomorrow. thanks again for a quick response .
