I was checking out the car prior to next weeks dyno testing and looked for a leak at the PCV hose. When I put my hand on the hose, I felt pulsations in the hose and heard the ball inside the PCV valve bounding up and down. Is this normal? It seems to me that the vacuum should be constant and hold the ball into an open position, not having the check ball openinng and closing rapidly. This tells me that my vacuum is pulsing which means that one or more cylinders is not operating correctly. True? False? Could it be that I have a valve adjusted too tight and it is not closing all the way.
Could someone tell me whether the PCV valve on their 302 is "bouncing" the checkvalve when the engine is running? What do you suppose this indicates?
Perplexed on this one. Maybe this is the signal of what is the illusive problem I have been chasing for so long.
Rebuilding a classic mustang is a reality check on your individual state of perfection.
