Yesterday I finally got time to readjust the valve lash, I started with cylinder #1 and followed the directions in the sticky for "Tech article directory" subtitle "valve lash adjustment." I backed off the adjusting nut and let the lifter and pushrod sit with no pressure for about two minutes and then start to tighten the adjusting nut while turning the pushrod and once I felt a slight resistance then from there I turned the adjusting nut 1/4 turn. I did all the valves this way, then started the car and it sounded terrible so I quickly turned it off, checked the oil and it was about a quart low so topped of the oil started it back up and still didn't sound good, then tried it a couple more times and then it quitend down. Now the thorttle respose is much different and it sounds different but a good different. Was the reason for the initial noisey start up is that the lifters had build up oil pressure to tighten up the lifter and pushrod???
