It sounds like a bad phaser. Do you have a scan tool with live data?

Problem with the rocker arm spring is possible ??
Customer: replied 1 year ago.
The engin was out of the car during few weeks, without oil
Expert:  Wayne Crawford replied 1 year ago.

I dont think so. I think its a problem with the phaser. What are the phasers doing when it starts running bad?

Customer: replied 1 year ago.
no i start cold engin without problem, no noise and with good engin power, only after few km (engin hot) the noise is comming and the power engin is down.
Expert:  Wayne Crawford replied 1 year ago.

So youre telling me that a base engine mechanical problem would wait a few KM to appear?

Customer: replied 1 year ago.
with cold engin is perfect.
Expert:  Wayne Crawford replied 1 year ago.

Mechanical problems as a rule do not tend to come and go. Electrical problems do.

Customer: replied 1 year ago.
i think, after the deconnection of the battery, the engin run correctly por few minuts
Expert:  Wayne Crawford replied 1 year ago.

Again that points to an electrical issue but you are telling me its a mechanical issue.

Customer: replied 1 year ago.
I find, the noise is mechanical, but......
Expert:  Wayne Crawford replied 1 year ago.

The noise is mechanical but the symptoms point to the cause being electrical.

Customer: replied 1 year ago.
