96 cobra motor knock when cold

[Gforceman]

i did a search so i had to post this ques - when i start engine in the AM or when ever the engine is cold i hear a a tap knock not a rod knock maybe a cam or valve prob after the engine heats up the noise goes away , and only under power ( when driving ) maybe comming from the driversside of motor , maybe a timing chain tensioner? theres 118k on it , i changed the oil to see if the noise would stop but it didnt ,oil pressure is good , is the valve train supposed to be noisy, im gonna use a stethascope to see if i can find where its comming from but any oppinions ? thx

i hear the noise comming from the drivers side rear side of the valve cover

If it only does it on start up in the morning, it could very possibly be starving for oil because the filter drained out. Change to a Motorcraft FL-820S filter and try again. This is a very common problem. The Motorcraft filter has a good anti-drainback valve in it.

Had same problem in mine, thought it was in the valvetrain but it was actually my tenioner pulley going out. Bearings were makin all that noise. Mine went away after warm too.
