[QUOTE="Patrick Feeley, post: 1552036, member: 2142"] In a nutshell: When the engine is in the 11 o'clock position, there is a drain path for oil to drain from lifter galleries. If it is not and there is residual oil pressure, when the pushrod is removed the lifter can jack up (effectively get longer ... they are hydraulic lifters vice solid lifters). If the pushrod is put back in it can cause the valve to lift more than it should and you could end up with the valve hitting the piston ... not good! Cheers! [/QUOTE]
