A Volvo V8? Well actually, a Yamaha V8, In a Volvo. Can they fail though? Well this one is purportedly bad, so today we are going to tear the whole thing down to try to find out how. This is the Volvo B8444S 4.4L V8 from a Volvo XC90 or S80. These are remarkably reliable engines and I've had MANY people ask to see one on the channel. It has taken YEARS to find a bad example to teardown. So, what happened? how did this engine fail?
