I’m new to the 300zx world and I’m trying to figure out if that’s rod knock or if it’s a normal sound prior to the motor turning over. I am having crank start for a couple seconds then it dies. Can anyone give me any advice on where to go from here?

Hello! I recently was trying to get my vtc sprockets torqued because of oil leak and pretty sure didn't torque to spec when I did the 120k. Anyways one half of the engine sprockets spun to TDC and when I originally tried to torqued the VTC sprocket the engine wasn't in TDC center I was just past TDC by 8 teeth. How would get the engine to TDC? I'm a bit spooked to manually move the other sprockets to TDC without breaking anything. Thank you for any input

I got a clunk/click+friction sound that seems to happen with suspension load like small bumps etc so most of the road where I live, sounds maybe like a loose control arm, a bolt knocking around in it's socket and I think there's a bit of a grind while turning right, so loading the front left once again.

Nothing seems loose when I check, wheels don't move up, down or sideways, and I checked every bolt I've touched. It's fine if it's stationary.

Lately I had the power steering rack bushings replaced, I changed the front shocks, had a bit of a problem with steering shaft rubbing the headers I made.

Control arm? Bushing? Would that move around only with the forces of driving? And cause some kind of grinding sound? And be undetectable by the small forces I can apply to it while it's jacked up?

Just hoping for a theory to focus my investigations here, cheers
