NA 1.6l, rebuilt. Diesel noise from the head.
 

Just put in a freshly built motor. 1.6l, scat rods and super tech pistons, rebuilt head.

Here is a video of the noise


Noise is louder when the car is called.

First oil chage was at 100miles, replaced with 5x30 castrol regular oil.

Any idea what the noise could be?

Can somebody please move this. Somehow it got posted in a totally wrong section. Stupid phone.

My car started doing this since switching to Rotella fully synthetic..... I dont know if the heavier weight oil is what did it or if i just noticed it after changing oil, either way im interested for someone else to chime in.
