The click sound upon turning on the ignition is, I think, the adjustments. The sound afterwards, is still the same sound I could hear when the old servomotor was installed. The second sound is like the camshaft returns back to its point, therefore skipping the wormgear teeth.
Is this normal?! |
I believe there is a programming procedure when you replace the VVT. It sounded like it did rotate correctly at first, but then I definitely hear some sort of grinding. |
I went back and watched the startup videos I'd recorded with the old servomotor, and noticed similar noises! Maybe the new one sounds a little louder.
