Yeah, the lifters are new, and they rotate freely. I'll try to take some measurements tonight to see if the lifters are completely compressed when they are on the "back" of the cam lobe. I guess nearly compressed would be enough to lift the valves off their seats when the oil pressure pumps the lifters up. I'm not sure how these lifters are designed. With adjustable valvetrains on American things, you usually go to zero lash, then compress the lifter about .050".(1/2 turn). I wonder where I am with these volvo buckets.
