I just remembered something else I read about the center locks failing on the intake camshaft phasors. If they hang up and can't park, they flop around until pressure hits them.


I suggest pulling the timing cover to check the intake vvt phasors and the preload of the timing chain tensioners.

update... I finally figured this out. It was the vvt intake cam gear. Something broke inside of it and made this sound till oil pressure increased.

I installed a new one and it's fixed. Hopefully this helps if someone finds this...

Thank you for sharing the fix, it is not often that people do this and it is a big help to others in the future.

Thanks for confirming. It makes your recording an excellent reference.
