I have an 2010 m8 pg with 09 head and every time i make a long pull the o ring in head blows out and starts leaking. It's happened 3 times now,at first i thought i pinched it but after doing it my self and then the cat dealer in larimie and cooke doing it there has to be something else. I'm running 8# with 3-4 gallons race fuel. Do they make heavier o rings or could head be warped anybody have this happen or have any oring ideas? thanks.
