1978 L48 EGR Valve Assembly - OEM Number(s) (EG10132)
The EGR valve controls a passageway between the intake and exhaust manifolds. When the valve opens, the intake vacuum draws exhaust through the valve. This dilutes the incoming air/fuel mixture and has a quenching effect on combustion temperatures. Always make sure to replace your faulty EGR valve with the modeld that corresponds to your year/model's engine.
