Timing chain questions
Does the 911 have an interference engine? Do timing chains ever need to be changed? Do they break? When I first got my Carrera, a Porsche dealer service manager (Lujacks, Davenport, IA) tried to persuade me that I should get new timing chains at 60K, for a mere $1300. But since it was not listed in Bentley as a 60K service item, I declined.
Timing belts have been on my mind since I saw a '95 Audi A6 at the local dealer having a $3500 top end rebuild because the timing belt broke at 73K. So I promptly had my A6's timing belt replaced at 55K.
So then I asked local Ford dealer if my wife's 97 Escort has an interference engine and he says yes, and change it at 60K. Then I read in Chilton that it does not have an interference engine. So I figure, what the heck, just wait until it breaks. Does a broken timing belt do an harm in a non-interfrerence engine?
