it doesnt seem to me that trying to set the lash while its running can be very accurate and i would not attempt to. i started with the number one cylinder int/ex valves.with the engine warmed up and not running, i bumped the engine around untill the intake valve was partially open and the exhaust valve all the way closed, then setting the exhaust lash at .20 and then bumped it around untill the intake valve was all the way closed and the exhaust valve partially open and set the intake valve lash at .10 and so on and so forth for each set of valves. bringing the number one piston to top dead center and attempting to set the lash for it did not seem to be working for me although i did not spend any real time trying it that way because you would have to do that for every piston and it was just easier to bump it around (using the starter relay and a screw driver). did i do this correctly????? did i obtain the proper lash for each valve doing it this way? after buttoning it all back together and firing it up,it was so much quieter and smoother . but as my luck would have it , now i can hear a slight knock coming from the engine that i couldnt hear before over the loud valve noise...real bummer. how long will a slant six run with a knock before it explodes, given that it has 10/40 pure synthetic oil and doesnt get driven over 65 miles per hour? anyone know????
