Hi everyone, about two months ago I did a gallery gasket on the 370z and replaced the timing chain and tensioners. Everything has been good since but two days ago the front of the engine started making a rattling noise behind the timing cover at 1k rpm. Not sure what the problem is but iming thinking its related to the brand new chain. I used all oem parts from z1 and followed the fsm to the T with torque specs and all. Any ideas? Not sure if its even safe to drive. There is no rattle after 1k rpm or before it.
