Hello, i'm just continuing on the process of cleaning, and replacing old parts from the L28, unfortunately today one of the nightmares that nobody wants happened to me , the two bolts that hold the water inlet(coming from the heater) broke inside the the timing cover, , i had already deal with a situation like this before when i was barely trying to get the 280z running (thermostat housing), today however, the studs are almost all the way in... my question,.. is there any way to remove the timing front cover(whole oil pump, dizzy, etc) without messing up the timing? , I know I could use one of those kits to remove broken studs, but right now I could have access to a chrome cover for cheap, and I would like to take advantage of it, if possible.

thanks guys ..

 

You have to take out the oil pump & distributor shaft to remove the timing cover. It's easy to install if you set the engine to TDC at cyl #1 and line up the oil pump marks (discussed in the FSM / Haynes).
