Wow. Thanks for tHe tip, but I have to say Im not that ambitious. Many many of 986 and 996 motors rattle on startup but apparently there is no correlation between start up rattle and engine failure. Its one of the quirks of the brand, like when I had Alfa Romeos, the synchros were horrible, but you learned how to double clutch and they drove wonderfully.
