Subject: Re: Blown Head Gasket question

Hi, Thank you very much for your response. Today, after speaking with my mechanic, the new estimate is $1500. This will include a .0005 in machining of the head and polishing of the valves (I guess I really don't have a choice here), replacement of the gasket, replacement of the water pump, and flushing of the coolant system. All in all, a lot of money, but I do love my car; so, I am going ahead with the repairs. Thanks again.
