my 960 has developed an oil leak from the cam timing sensor. the volvo dealers estimate to fix the problem was 6 hours labour and and a cost of approx. $600.00 . i was told both front and back seals should be replaced.
other shops in my community where not sure the exact amount of work involved. what is the procedure required to correct this problem?

There is almost no overlap of work to change that rear seal by itself. It requires removal of the cam sensor (2 bolts) and the shutter piece from cam (1 bolt) and then the seal is levered out. If you replace the front seals later the cam sensor and shutter wheel would have to be removed again. Volvo has a special tool that pushes seal back in using the threads in end of cam for the shutter wheel. It should be about one hour labor for this. If they service flame trap that would be more. The seals on front of engine would be only be a couple hours additional to have changed the next time the timing belt is in need of changing as the timing belt is removed to get access to seals.
