slantsix valve adjust

Oh yes!, many times have I adjusted the ole valves on my '70 Dodge. Love the way those clattering valves sound when your done, plus you can always tell when you have a little more noticeable power. Have always adjusted them HOT, but don't like cascading oil down the side of the block to the floor when oil gets hot. Have tried damming up with rags and towels but still don't like the mess. So my old mechanic father gave me this idea. Take a spare unused valve cover and cut the top off of it. Put that cover back on again as you would've when completing your job (adjusting the valves). Fire the car up,start adjusting when it gets hot, now you may have to get the feeler gauges that have the angle bend in the end of them to come into the rocker and push rod at a different angle. No big oil mess and when your done remove your revamped cover hang on wall or wherever until next time. Thanks, AL
