Depends on the size of the leak. A week of operation should be long enough if not sooner.

2. UV dye and a check for leaks in 500 miles is a good idea.

Or use a good electric leak detector.

Image is hard to see as it's small. What I can see looks like it might be a sealer.

Separating the harmonic pulley would take tremendous pressure. If the compressor works and is not locking up. The option is to remove each item and blow nitrogen through them.

Sounds like maybe a leak sealer was used?

We supply that shaft seal for a cheaper price. Plus would add support behind it over your Rock Auto and eBay purchases. Got to love the internet.

Follow up after you get it checked out.
