But if it's cracked through to the where the high pressure oil is pumped to the turbo it's going to spray rather hot oil all over your engine bay, I'm sure I don't need to tell you that's a bad thing!
Tring to Tig weld with the head on the car will be very hard plus you are going to have oil contamination which will lead to a horrible weld which may not seal.
You're going to have to bite the bullet and remove the head, tring to bodge it will probably lead to a fire!
