Ken...im sure everyone on this site has had their own version of a WTF moment. like me at SCR this year. we could not figure out why we kept getting that pesky little oil leak. it started blowing oil out the dipstick tube...sealed that up..then started pushing oil out the valve cover stud holes..sealed that up...then started leaking out the front of the intake(at SCR)took intake off and re-sealed that up..then started leaking out the BACK of the intake...keep in mind that i have the aerospace 3 vane vacuum pump.....so i bought a boost/vacuum guage and at idle was making 7 lbs of boost..my WTF moment...should be at least 2-3 in. on the vaccum side of the guage..called aerospace and they didnt really have an answer for me..i sent some pics to them for the heck of it and then they had my answer......normally they mount on the pass. side of the motor..mine is on the drivers side 'cause it wouldnt work with the aerospace elec. water pump....go figure..what they found was when you have it mounted on the pass, side you use hole A for inlet to pump..and on the drivers side you use hole B as inlet to pump..well.....we used hole A so we were actually making boost instead of pulling vacuum......remade new lines and now make 4 in. vacuum at idle and all dry underneath...whew!! but unlike you......i only used WTF 1 time.....
