Myself, I might be quite willing to clean things up, install fresh head gaskets and run it until it gives up again.
Unless that crack gets into a cylinder wall or worse it's not going to hurt much...
Knowing when it got there is not possible....
50K miles...100K miles, 200K miles....Maybe sooner or later....
Are the outer holes the large or small bolts ????
I was wondering about that... no telling how long the crack has been there. It could go a long, long time as is. The outer bolts are large - same diameter as the inner bolts.
