Michael, from what I could see, the VC gaskets were leaking. There was substantial oil around the dip stick, for example. Underneath the engine passenger side was soaked.
I am not saying this caused the alternator failure.
The alternator was putting out under 10v at idle and could not support driving.
I got a good recommendation for the shop, "Bobby's Pit Stop" near Dominican Hospital. I know you know the area.
The parts prices were high; like $450 for the Denso Reman and over $300 for the tensioner assembly.
I did the plugs...
Ouch is right... Ha! Sometimes ya just gotta deal with it.
