very true. turbos have a different setup.
Bill, how did you pull the oil pump sprocket with the upper pan on? that thing never comes off for me without a puller.

BTW, you don't need to remove the upper oil pan to replace the oil pump, as some say. I did so w/ engine in car, but only to replace the broken plastic chain tensioner which installs on the main bearing cap.
