"I replaced all 16 and the issue was fixed for a few thousand miles and the smoking began again along with some oil consumption (I cleaned the VC at the same time which is probably what temporarily cured the smokey start up) ."
"This is the new updated version of the driver side valve cover for multiple GM vehicles."
"Perfect fix and fit, eliminated my oil consumption and extended and maximize my oil changes, love it."
"I will make an updated post in a few months to report on the oil consumption of my 05 silverado which did have the valve cover with the badly designed pcv system."
"Oil being sucked into engine was causing a rough idle and fouling plugs."
"Genuine GM updated valve cover - Solved my 2007 Yukon oil burn issue."
"Didn't work...still let oil into intake...I did away with this style and used earlier style cover with external pcv valve....fixed oil consumption... usually very happy with AC delco parts...maybe I just got a bad one..."

Find Best Price at Amazon"The ball bearing has a flat ground in it where it contacts the valve stem but the ball, of course, turns and so you have to be very careful when adjusting the valve gap because it is hard to see if you are on the flat or on the round area of the ball."
"Worked great but you will need more shims for,proper,valve adjustment."
"Great valve adjustment screw, just get the extra shims you will need them."
"Just what i was looking for."
"~These 'Ball-foot' adjusters are quite good in comparison to the other type wide-contact 'elephant-foot' adjusters (-which may seem like a good idea, --but they are actually terrible and can damage your engine, ---as they very soon fail and come-apart, because they are not properly engineered for lubrication), -but this long-lasting 'Ball-foot' type have the proper lubrication-passages provided which correctly feed oil from the rocker-arms!"
