SYMPTOM/CONDITION
Some owners may express concern of abnormal oil consumption (1 qt. per 400-500 miles) on 1987-89 domestic vehicles equipped with the 3.0L engine.
In addition they may complain of lack of power, rough idle, hesitation and driveway dieout.
This condition may be the result of sludge accumulation in the left bank (FRONT) rocker cover baffle oil drain hole. Plugging or restricting of the baffle
oil drain hole may result in oil pull-over into the PCV system.
Figure 1
DIAGNOSIS
Remove the MAP sensor hose and PCV hose, inspect hoses for evidence of oil accumulation. If oil is present, remove the left (FRONT) rocker cover.
Inspect the inside of the rocker cover for sludge accumulation and/or a restricted drain hole, Figure 1. If there is an accumulation of sludge or drain hole
is restricted perform the following repair procedure. If the rocker cover is free of sludge and the drain hole is clear, perform an oil consumption diagnosis
as outlined in the appropriate Technical Service Manual.
