i actually called a local machine shop and we decided that a heli-coil would not be able to hold the amount of pressure needed for the oil supply. the machine shop recomended doing a threaded insert for $40. but of coarse, he will require me to remove the engine befor he will do anything to the block. I had thought about trying a thread chaser but so far i have had no luck finding any at all. does any one know where i could get one?

thanks again,
p.s.
i also had ordered a new banjo bolt from nissan for a z32. the new bolt is the same thread size and pitch but the hole through the center is conceterably smaller. i know this would probably increase oil pressure but im not sure why mine is different from the factory bolt. any thoughts?
