I rebuild and assembled 1993 Mercruiser 4.3 v6 engine on my Bayliner Capri. Of course I forgot to adjust the rockers and fine tune the valves when it was easy and the engine was out of the boat. Now I had to do this after all was assembled and I had to adjust the rockers by the sound. I tightened them a little while engine was running so they stopped making knocking noises and then one by one got them loose and tightened until the noise disappeared and then 3/4 of a turn. Are there any suggestions about better fine tuning them without taking the risers and exhaust manifolds off? Also I noticed that I cannot remove valve covers without untying the riser bolts and lifting them a little. This is on the top of removing the shifting linkage on the starboard riser and I think some ignition module on the port side. Any secret to easy valve cover removal? Thx for any help, greatly appreciated.
