Pre 06 some of the housings used steel rather than plastic oil control rings. The steel eats into the VVT adjuster causing pressure problems and the timing fluctuates. You will also snap any of the rings trying to refit the casing as they get caught on the grooves.

Yep that happened to me. The middle ring snapped, which caused a god awful rattling from idle to 1500rpm when up to temp, which took an age to diagnose due to sound reflections through the engine. It wasn't until I disconnected the N205 solenoid that it shut up, which then pointed me in the right diagnosis direction.
Thankfully the inner and outer ring didn't snap, so the VVT function still worked at least.
My engine was a plastic ring job from the factory and the wear grooves were barely felt on my finger nail, so you have to be super careful to slide the chain cover back on dead square.
