my buddy wanted me to post up his situation and see if anyone had any ideas as to what is going on.. he put a brand new oil pump on his stroker 2.1 turboed gsr and the pump sucked up about 1 quart while cranking the motor to prime it.. and it is still pumping fine to our knowledge but there is no oil pressure coming out of the back of the block where the sensor goes.. he took his valve cover off and he said the head appears to be oiled- everything looks wet and is wet to the touch but still no oil pressure at the back of the block.. clogged oil passage maybe?? any help is greatly appreciated. thanks in advance

 

ok we found out when the machine shop assembled the block they neglected to put the oil squirters back in
