1.5 d15z. And makes that noise at all temps. That video is of her warm. Had already driven for about twenty minutes before hand.
I'm not as religious as you with your warm up but being a biker for ten years, I've always been kind to engines from cold. As far as I know oil level is fine but I'll check on it now. Not overly helpful living in an incline! Recently did a service (plugs, oil, oil filter, air filter, fuel filter). It was making the noise before. Everything cranked up to correct torque settings and plugs definitely not cross-threaded! Old plugs looked in fine condition and cross checked them with what normal working plugs should look like.
There's no smoke anywhere that I can tell. When I start her up later on and tomorrow morning I'll check. As far as I can tell she runs relatively fine. It's just a weird noise!
The only thing that isn't stock is the lightened flywheel, but it was making the noises before.
