Mustang Valvetrain Noise - YouTube

Any thoughts on what the clicking on the drivers side might be? The passenger side lightly ticks but there's one noticiable click coming from the drivers side right around the middle of the valve cover. I tried moving the camera all over to give a general idea of where it's coming from. The camera makes it sound louder than it really is. But none the less it sounds ghetto as hell and I can't wait to get it fixed.

exhaust leak?

Nah, fixed those when I put the spark plugs in. It's almost more of a clatter type noise on the passenger side and the driver side is definitely something actually clicking. IDK if it's a loose rocker, fucked up pushrod, or what. The car still runs fine and you'd think it wouldn't if it were something like that right?

Rockers...

do you have factory rockers? it definately sounds like valvetrain noise. i would check with a scope or a long screwdriver against your ear to be sure where its coming from. to me it sounds like a rocker is loose as fuck, but you shouldnt have to worry about lash with it being hydraulic roller lifters. what does your oil pressure look like? you should check your oil and coolant after its warm too and see if there is anything going on there. you could have a spun bearing...ive seen motors even keep good oil pressure if the havent been run long with a blown head gasket and the bearings looked like hammered ass when i took it apart.

Lol I just saw your reply. To my knowledge its got factory rockers. It's a long story but I am almost 100% certain it's got a flat tappet cam in it. It's been doing this for quite some time, so I think if it were anything major it would have failed by now. I've taken a small hose and used it as a stethoscope and it seems to be coming mostly from the top end on the drivers side.
