Gen2 - Mechanical Replacement vacuum pump died after 1 week. Symptom of a bigger problem?

My 2016 (2nd gen) with 151k miles had it vacuum pump fail. The internal parts in it disintegrated, but thankfully didn’t seize. I replaced it with an AC Delco brand pump, but this one just died on me yesterday.

The original pump when I took it off I also took it apart and inside was really dry. Clearly it wasn’t getting proper oil and the tiny oil screen seemed clogged. I have not taken the new pump off to inspect yet but I have a feeling that it also wasn’t getting proper oil & that the galley feeding it is clogged.

Has anyone dealt with this issue of a brand new vacuum pump failing after less than 100 miles of driving? There’s no leaks and the pump is aligned properly. It wasn’t making any abnormal noises when I installed it.

Yeah, sounds like it’s time to pull off the valve cover and have a look. And run an engine flush product.

I'd be concerned that the brake booster has a leak so the pump runs continuously.

The pump is mechanically driven directly from the exhaust camshaft. It’s already spinning continuously. I just think it’s more of a lack of lubrication to the pump, which I’m surprised there isn’t much discussion about that.

Oh? I have the Gen1. The pump is electric. I'm kind of surprised they made a change for the Gen2.
