I have a 2011 Chevrolet 2500hd with 6.0 gas engine and automatic transmission. For the past month I’ve been hearing a ticking noise when I start the engine that last for maybe 10-15 minutes until the engine is warm then it goes away. I noticed today that 2 of the bolts that hold the exhaust manifold to the engine are broken off. I’ve also noticed my motor oil is dirtier than usual for only having 2500 miles on it. I’m making plans to get it fixed but my mechanic is busy until after 4th of July. I’m also driving to California for the holiday, it will be about a 310 mile drive each way, I’ll probably put 700 miles on the vehicle.
I’m wondering if it is a bad idea to drive the truck to california and back with the broken exhaust manifold bolts? Also, what is the best way to repair the issue? My mechanic hasn’t looked at it in person yet.
You'll have to remove the manifold first. If there's enough stud left in the block, you can grab it with vicegrips, heat it up with a torch and unscrew it from the head. If not, the easiest way is to weld a nut to the stud and back it out.

Yes exhaust leaks will cause the engine to run incorrectly, potentially causing more damage.
