I have an 88 firebird v8 and recently had the clutch replaced. I drove it for a week and just one day it shut down and wouldnt restart while i was driving. When it shut down there was white smoke that was pouring out of the exhaust. When I turn the key I can hear the starter and fly wheel turn over but the car will not start. My oil and anti-freeze are fine. My car also has a history of over heating. Any ideas on what could be wrong?
