So my friends victoria was making some nasty noises from the valve cover area. We removed the cover and I instantly noticed the adjusters were run all the way down no adjustment left at all. We removed the rocker shaft and found the rockers had about 3/8 of slop the shafts badly worn and the rockers egg shaped. The rocker shafts seemed to be clogged And no oil was getting up .  We spun the engine with out the rocker shaft or push rods in place and he did have a flow of oil coming out of the head. So we have ordered new shafts and I have some left over rockers .  He has had the car a short time we may be in for other surprises
