i have a very misterious knocking from my car like a loud tapping appears to be coming from the top. the noise is slower than the engine idle but increces when you rev. it starts up everytime and all of a sudeen just started tapping. does anyone have any ideas or information?

this could be the hydrolic tappits(rattle when oil gets thick) is your car due for an oil change?

it sounds louder than the tappets n it sounds near valves

if th car is high milage it could also be the cam chain tensioners starting to slip as these are made of plastic and ford recomend renewing them at 120000 miles
