OR 5.0L V-8 (VIN CODE Y) ENGINE
Some 1983 Oldsmobiles produced prior to March of 1983 and equipped with a 4.1L V-6 or 5.0L V-8 engine may develop a restricted exhaust due to the
catalytic converter becoming plugged. This can result in poor engine performance or a no-start condition.
Effective with this bulletin, subject vehicles which are determined to have a restricted converter, are to be repaired with the converter kit package which
includes a converter shell with beads in the upper bed and a plug for sealing the lower bed after installing beads per the instructions in this bulletin.
