I have a 2002 2.4L Toyota Camry w/228,000 mi. Failed smog; error codes P0301, P0302 and P0420. Voluminous cloud of blue smoke on start up, a fairly substantial oil leak that drips inside and slightly to the front of the right front wheel and starting to lose coolant. Head gasket? Maybe, but my guess is stripped head bolts, very common for that engine. Does anyone know of a repair shop in San Diego (preferably CAP approved) that has experience with this problem?
