Ever have to remove the oil pump nut?  Don't want to remove the pump first?

 

Note the piece of aluminum placed between the timing pulleys.

When I did it I think I remember taking off the whole pump, and then you can hold onto the other side to get the nut off. 

Easy way i have done without taking the pump off is by placing a rag around the oil sprocket and using a oil filter wrench to hold it in place while you wrench to nut off.

loosen the nut before removing the timing belt

use the old timing belt as a wrench, thats how i tighten everything in the timing side.
