The gravity damper seals require a fairly specific type of foam.  If the
replacement foam is too thick or too dense, the minor weight of the damper will
not force the foam into a tight seal.

Regarding your efforts to rejuvenate the blower motor, in my experience such
efforts produce short-lived results.  I've even gone to the trouble of soaking
brass bushing bearings in heated oil.  The results were always the same: the
motor would run great for a short while then stop working all too soon.  I
tend to think that once the pores of an Oilite-type bearing become glazed or
filled, they is little which can be done to renew it.

I've never had the occasion to attempt it, but perhaps with some careful work
the bushings of a Vanagon blower motor (and the brushes) could be replaced.
It might require machining an Oilite blank to an oddball size.  Short of that,
it is best to replace a squealing or locked blower motor.
