  1. I have the B481S11 chain driven petrol engine in my Volvo V50 and I have found it so reliable. It’s never broken down in the 9 years I’ve had my car and I bought it with 75k miles on the clock. It’s now done 122k. It gives plenty of punch for a 1.8ltr. Change the oil/filter regularly every 6k.
