Noooo don't break it, yours is one of the nicest around IMHO, Best colour and best wheels
not too sure on cossie oil pumps but if lobes on the rotor bit or the actual casingwear then it can cause oil to pass and not create the pressure needed, i've heard of this happening on other cars but like i say, unsure on cossies but they are all pretty similar.
how old is the pump?
