2000 A6 4.2 Cracked intake....
New Audi owner. Just recently purchased a 2000 A6 4.2L with pretty high km's.
Aside from a few minor issues the car is in good contidion. However The other week when my father borrowed the car. When trying to start it he heard a loud bang followed by smoke from under the bonnet. He wad able to get the car started and nurse it home.
I have pulled the engine covers off to inspect the problem, and discovered that the intake manifold has a massive crack.
What would cause this to happen? The car was previously running fine.
I can replace the intake but want to be sure any underlying issues are resolved to avoid a repeat. I have tried a search but not found anyone else who has had their intake crack.
