Yeah, don't ignore coolant or oil leaks like @D_Walt said. Most oil leaks are from hard brittle valve cover gaskets and at that point, you're halfway through getting to the timing chain guides. Just food for thought.

So I was also told it might be the brake vacuum pump, but it wasn’t. Having that re sealed during this chain guide job because. To @djkaosone point, it’s a lot of the same labor if it is a timing cover or valve cover leak so if your on original chains and plan to keep it, maybe have that is a smart play. It would solve all the common oil leak spots, aside from the vacuum pump.
that’s why I decided to have my guides replaced.

I've had the vehicle back for 6 days and heard this noise last night. Started as what sounded like a small electric hum / whine that we could hear driving. After getting home and sitting idle it got really loud. At first I thought it was a belt, but it doesn't sound like the usual belt scream I know so not sure.
**Just started it up cold this morning and the issue wasn't occurring, looks to be something that happens after the engine is warmed up and has been running for a while.
