Update.

Noise was from a bearing in the alternator. After being in the shop for 3 days. The following were done.

Alternator
Water pump
PVC hoses due to oil.
Belts etc.

Thank goodness original warranty is still active. Make me question reliability for major parts to fail at only 43k on it.

Hope this is the last one.
