Farked exhaust manifold stud hole.

[josh_tsv]

Hey all, one of my exhaust manifold studs has pulled out of the head and farked the thread. Should I drill it out, retap it and use a bigger stud, say 10mm or so. Or should I get a heli coil kit and do that instead. All help would be most appericated.

drill and tap is cheaper
helicoil is pricey if u need to buy the tool

if u have the tool, its cheap

its completely up to you mate
if your gonna drill and tap, u could possibly do all of them!!..
