Does this sound familiar to any CEGers? I took my SVT into the shop today because it started to make a noise. The guy there called me and told me that there was something wrong with the timing chain inside the motor. The motor chatters and makes a weird pinging sound when it is idle. Then he told me that he couldnt fix it, you have to pull the motor and replace the timing chain etc., and it's very expensive to do. Is this true? Is this an expensive fix or something that I can do on my own?
