Excessive Oil Consumption On
1986-94 Saab 2.0L DOHC Engines
AERA members have reported excessive oil consumption on 1986-94 Saab
2.0L DOHC engines. The source of this oil consumption has been traced to the engine's positive crankcase ventilation system (PCV). Apparently the original camshaft cover allows excessive amounts of oil to enter into the induction system.
A modification was made to the camshaft cover Part #8788135 during the 1994 production year to reduce the amount of oil mist reaching the PCV system. The part number for the cover, however, did not change. The identification of the revised cover, requires removing it from the head and inspecting it for the additional tube shown in the illustration below.
