Hi all.I need to know if the oil pump can be remove on a mc8 with a 8v71 without moving the moter back away from the rear moter mount that bolts to the center of the engine? ::)Im in the process of rolling in new main and rod bearings. and i wanted to cheack out the oil pump. thanks. :o
On most (not all) 8V71's in MCI's the oil pump is gear driven and is in a scroll in the front seal cover of the engine. You take the front cover off the engine to get at the oil pump. On other 8V71 engine types the oil pump is bolted to the center main caps.
I don't think there is any need to do anything at the clutch end of the engine. Just take the rear bumper off and you can pull the pulley and spacer off, and the front cover should be able to come off. I don't think you need to take off the motor mount.

Most MCI 8's and the 8v71 MCI 9's have the oil pump inside the pan on the engine pita but not a bad job
Well got my oil pump removeded today. Only issue i ran into was i had to remove the front seal to allow the pump to get past the step in the crank. pump hast to be removed on a angle.pump is in good shape. so it will be going back on. thanks for the replies. ;D
Check the spacer sleeve that the oil seal rides against to see if there is a wear groove. If there is, you can replace that sleeve quite inexpensively when you put it back together. I got one from Luke. The crank bolt torques to a highish number, around 350 ft lbs by memory.
