hi i have an 85 w/ stock 12a in it some times i can hear a knocking not sure what it is but it goes away im thinking maybe a blown out apex seal or something on that line any info will help out

also i can only hear it when idling and when i noticed it i started losing a little bit of power and it always missed a little but now its more frequent... put new plugs in it and what not...
