I agree with Mayer, anyone who can't figure out how to make a 100 degree turn shouldn't even open the hood yet alone ATTEMPT changing head gaskets. It happens all to often, Mr. Know-it-all attempts a head gasket change and ends up bringing to me afterwards to not only replace the gasket AGAIN, but fix the REPAIR job they added to the problem. Makes my world more work but thanks to these hot shots I get more money cleaning up the BS they added to the labor. Thanks Mr. Know-it-all.
