2002 Sentra Camshaft shaking/problem (video)

[emiliog2276]

I have a 2002 Nissan Sentra GXE, the problem i am having is that the car shakes and this shaking seems to come from valve cover area. Also at moments when accelerating from a stop i can hear a weird sound coming from the camshaft. I recorded a video of it, as soon as the oil cap is removed it starts spraying out oil like crazy Also when turning off a sound comes from what seems the camshafts, (in video can hear better at second shut off). What can this be , on my way to a broken camshaft, or can or can it be one of the camshaft brackets?Thanks.

Here is video.

Is it coming from the passenger side? I'd say something to do with the timing chain...maybe stretched out? We see them from time to time at work.

Hard to say since valve area is oriented horizontal rather than than vertical i dont know if its the intake or exhaust camshaft. Thinking of removing valve cover and checking camshaft brackets.

Check your actual timing chain...they tend to stretch every once in a while.

So i have to remove the valve cover to see actual chain? How would i know if its the chain?
