Anyone know what is making this sound?
I get it on cold start ups, It shakes the car, I can feel it on the throttle, under the car and engine bay. The sound comes out often after low revs. Like in the video, I tap it lightly and it makes the sound.
It goes away after warming up or driving after 10 minutes or so
I'm suspecting it might be either the motor mounts or transmission mount. But if it goes away after it warms up, that wouldn't make sense would it?
Any advice is appreciated, thanks

Sounds like the oil cap is wedged on top of the transmission. This is a common problem, get in there with a light and look for an old/current oil cap.

 

actually you might be right, ill check tomorrow! when i bought the car, the owner did say the cap came off...

doing my research on the problem, sounds like other people with the oil cap problem have the same symptoms, so lets hope its that
