Vauxhall Astravan engine making tapping noise
I've just put a second hand engine in my 2001 Vauxhall Astravan. From what I can tell, the engine was good and the only thing that needed changing was the fuel pump. However, I started it up and it is making a loud knocking/tapping noise from the top end of engine. Any ideas what this could be?

Might be an airlock between the fuel pump and the injector rail.

How are you able to tell if a turbo is not working on a Volkswagen caddy 1.9 diesel? My van is losing power and smoking when I rev the engine. It also wants to stall when I try to pull away.
