I recently bought a 1995 Eagle Talon TSI with 104,000 miles on it and decide to have the timing belt, water pump, pulleys and tensioner all replaced just to be on the safe side. While doing this the mechanic recommended I also do the head gasket since there was a small oil leak starting which I did agreed to do sense the motor was already apart. I got the car back yesterday and it runs great idols like normal but does sound very loud from inside the car. Outside the car it makes maybe a little deeper pitch sound from the exhaust but when driving it there is a noticeable vibrating and more noise to compared to how it used to drive. Is this normal?
