I have a 98 blazer 2 door 4x4, the intake manafold gasket went bad as i found was common with my model. Anyway i found how to take it apart and put it back together and at first it started up with a slight timing issue. (Had to take dissy out for first issue) Obviously im no pro and didnt properly mark my dissy, but now im at the point where ive finally got my #1 cylinder to tdc and i know where my dissy needs to be placed. The one thing i dont know and cant find videos or pictures of is how to turn the dang oil pump with a long screwdriver. Where is the oil pump, where does the screwdriver go, what do i turn, does it go in the dissy hole? HELP PLEASE! This is like the last step im at for all the other hard work with the gasket. I thought the gasket work was a pain, but this dissy work is really getting to me. Also does it really matter if u use dexcool or other stuff. Ive always used the orange stuff but have heard its what caused the gasket issue.

 

Screw driver or pump driver straight down the distributer opening The bottom of the distributer fits into a slot in the oil pump shaft.
