I have a 2012 Cruze with a 1.4l turbo. I am currently doing a head gasket on it and I have got all the head bolts out except for 1. The 1 I can't get out is an e torx 14 and i rounded it out. I could really use some advice cause I have tried using a smaller socket but it didn't work. I have no idea what to do. I could really use some help please.
Use a grinder to shape the bolt head into a hexagon. soak it in penetrating lube. use a socket and impact gun to remove the bolt. Worst case weld a nut onto it
