ClockworkC5
droog
when i first start my c5 i can hear a noise. that after a 15 seconds goes away. only thing i can think of is the oil isnt sticking to the motor so im getting dry starts. any other ideas? supposedly owner never put anything but mobil syn. in it. ive got paper work for most oil changes and thats accurate. ill pay more attention after i get out of work and post more on it.
