It only had 119,000 on it when I got it in my hands. I've had to do a few things like change the upper a arm's to adjustable a arm's to get the caster/camber I needed to fix my problem with tires getting ate up every time I turned around! And had to change the right rear hub assembly. The last owner's said they changed the left rear hub assembly and cat back exhaust system that has a low pitch that I like. And also the clutch got changed at 100,000. I'm about to do the timing chain because after warmup and when at low rpms just idling it sounds like a little bit of a chain rattle

welcome to the forum! Super clean car. Nice to know it’s already got an exhuast and a new clutch

The chain rattle is often caused by a loose main tensioner. The tensioner is hydraulically controlled… that said, you VERY LIKELY have the rear timing cover gallery gasket failure.

I highly recommend a whole new set of timing components and a new set of Z1 gallery gaskets. It’s a bit of a job, so have a weekend ready. It can be prohibitively expensive to have a shop do the work.
