So, what did you find? How did you have such a great cylinder leakage percentage with a valve hanging open? Was the lifter bottomed out to the point where the valve only closed with room temperature non-expanded parts,( i.e valve stem and pushrod) and was held off its seat when things hit operating temperature? If loosening the lash did this, that must have been the case. Hope your concrete project turns out as nice.
