Injector thread on head cracked making engine run like garbage
Yesterday I messed up big time by removing the injectors from my car. Injector #4 had seized on the head and my dumbass removed it with a massive lever on a socket, which cracked the head on the threads of course. There is a chunk gone from the head down to the injector heat shield shim.
I drove it like that and it made it even worse. The entire engine bay is wet from fuel spraying all over and it makes a sharp loud sound every time it goes on compression stroke.
If you wonder how awful it sounds, imagine running a gas engine without a spark plug. It sounds exactly like that with an attempt at combustion.
I know I messed it up and I am wondering if I can fix the leak with TIG?
I have work on Tuesday and don't want to cause further damage to it.
