I'm using THIS Melling Oil Pump, THIS Melling Oil Pump Pick Up and THIS ARP Oil Pump Stud. The oil pump pick up bolts to the oil pump. I was told to set the clearance between the bottom of the pick up and the oil pan anywhere from 1/4" to 1/2". I set it right at 3/8". That's not from the bottom of the screen, that's from the lowest part of the pick up to the pan. Should I still tac weld the pick up to the oil pump? Also, What should I torque the oil pump "stud" to the main cap at? And after that, what should I torque the bolt that go's on the stud that holds the pump at? I assume I should use ARP paste on both, right? If I do tac weld the pick up to the pump I have to remove the bottom cap on the oil pump and the oil pump spring before welding. What should I re torque the four bolts on the bottom of the oil pump to? And what do I torque the plug that holds the spring in place to? Thanks, NYH1!
