In my latest round of deferred maintenance.... as the weather gets cold in CT, the secondary air injection pump needs to do its thing. Mine started to squeal last year.
I have seen YT guys pulling the pump and lubing the bearings.
That seems a short term fix at best. Has anyone replaced the bearings? Seems like it should be straightforward. The issue is not starting the job that cannot be finished.
And yes, I know that others have removed the pump entirely. Not thinking about that yet. If it works within reason, I have no objection to using it.
But likely not going to buy a new one. Those are crazy expensive.
Thoughts?
