Service bulletin WB_557
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
Elkhart Brass and Akron Manufacturing ball-type intake and discharge valves have been submitted for warranty claims due to leaks within the seal of the valve. Neither manufacturer classifies a valve seal leak to be a malfunction of the product and therefore do not consider a seal leak to be a warrantable claim.
