Last year I broke a rocker and decided to refresh the engine in my 89 325i. New valve seals, rod bearings, rings, new rubber all around. I had a machine shop do the bottom end. I put it together, it sounded great, and about a month later, I get this noise. lol. Knowing that I'll be tearing it back down in the spring, possibly even scrapping the bottom end for eta crank and rods, I drove it a little around town this winter.
I know.
As you can see in the video, once it gets past 2.5k, the noise disappears, and as long as it's in gear, stays gone.

This morning the oil level light AND the coolant level light turned on the dummy panel. After adding about a half quart and checking the dipstick, I see the tiniest bit of milkshake on the top of the fins. So I guess I'll be dropping the engine sooner than I planned. What I'm wondering is if the apparent HG failure might have anything to do with what I suspect is rod knock or a spun bearing. Has anyone heard such a slow knock or is this super basic? Should I go ahead and buy a new set of bearings or just use this as a sign to source an ETA crank and rods? The HG was Goetze, BMW bolts.
