After unsuccessfully resolving an external coolant leak from under the no. 6 exhaust manifold port, I am realizing that I probably have to bite the bullet and replace the head gasket on our 1997 960. The car runs fine and to my knowledge has never overheated. The leak will empty the coolant reservoir in 1000 to 1200 miles.

While I can handle the wrenching aspects of the head gasket job, I know nothing of cylinder head reconditioning or machine work. I was hoping someone could educate me or offer some tips on what to look for and ask for from an automotive machine shop. Is it absolutely necessary to have the head reconditioned or machined? What service should I ask for?

Thanks in advance!
