Hi;
I have to change the oil pump on my 2003 Camry w/ a 4 cyl 2.4 engine. What is the reason for aligning the oil pump with the crank and cam? It would seem very easy to just undo the nut on the oil pump sprocket, and place it on the new pump. Is it critical to ensure that the mark on the pump matches with the marks on the cyl head and crankshaft? If so, why?
Thanks for any help. Pat
