If I pull my distributor to replace the O-ring, do i have to make sure my number one cylinder is in TDC before I reinstall it . I was told I didn't have to as long as I didn't change the position of the shaft when I take it off. Also is the O-ring on the distributor or inside the valve cover. I only ask were it's at so I know to get a valve cover gasket while I'm at it

 

No you don't need to be @ TDC. As long as you line up the distributor shaft properly with the cam shaft you're OK. There is only one way they will go together tight.

 

thanks ghost, appreciate it

 

You're welcome!
