Jim, I would guess that what is going on is that you are having a valve related issue. Either your valves aren't adjusted properly, you have a push rod that is not centered in a lifter (my bet), or that your lifters aren't pumping up and causing a valve issue that way. Pull the valve covers off. Look down each push rod tube with a flashlight. You should see the push rod centered in each lifter. If that is true then doublecheck your valve adjustment by turning the engine to TDC on each cylinder in turn and setting the valve lash to zero (just touching). If your lifters are soft you should adjust the valve screw until you can just feel the lifter start to compress as this will allow a spongy lifter to pump up properly. If all this checks out then you at least know that your valve timing and adjustments are correct and you can move on. Let me know if I can help you further, Ken Wilford John 3:16 www.vanagain.com
