Loud rattle or clatter from engine. Valve cover vibrates. No oil leaks, good oil pressure, no loss of power, no loose parts, slight drop in fuel mileage, no overheating, no check engine light.

1 QUART OF MARVEL MYSTERY OIL----SUBSTITUTE IT FOR 1 QUART OF MOTOR OIL--NEXT OIL CHANGE

THIS MAY HELP--IT WILL "CLEAN" YOUR TAPPETS (HYDRAULIC LIFTERS) THEY CONSTANTLY ADJUST TO TAKE UP THE SLACK IN YOUR VALVE TRAIN--IF THEY DO NOT CONSTANTLY OPEN AND CLOSE CORRECTLY YOU GET CLATTER.......THEY ARE SORTA LIKE A HYDRAULIC JACK OPENING AND CLOSING RAPIDLY.......CRAP MAY BE KEEPING YOURS FROM CLOSING.

EVEN THOUGH IT MAY TAKE SOME TIME,

DO RETURN TO THIS QUESTION AND LET ME KNOW IF IT'S WORKING,

THIS IS MY HOBBY, AND I DO WANT TO KNOW HOW THE SOAP OPERA IS PROGRESSING!

If the clattering/tapping continues after the use of the magic oil best open it up and investigate-if it turns out to be valve lifters the camshaft follows
