Sounds like this to me. My E11 makes a similar noise when I first start driving in the cold. After a minute it goes away, as the oil pressure builds up and the hydraulic lifters get their lubrication.Not a nice sound to have coming from your car.
Have you checked the oil level ?
Sounds far fetched i know, but the hydraulic lifters for the tappets need enough oil to operate correctly, if they don't have enough oil then the pressure to lift them drops and causes the chatter.
As discussed my experiences with Sineu over past year, can be a lot of things. Note is not helpfull in giving proper error codes. My warning, do not get in lot dealer expenses and plan their moves on their costs. If possible. Is the problem related to a certain level of idle and temperature? Was she serviced by with proper oil grade last time, is a narrow thing on a Nissan Note.Got a knock from my engine, I’m new to these cars so trying to figure out if it’s just normal or worse. My guesses are chain, tappets or bottom end, could anyone shed any light on it?
it’s an 08 Nissan note 1.4 petrol
