Bulletin 85-6-9
Date Apr.. '85
Ref. No. 85-206-6
SUBJECT:
INTERMITTENT OIL LIGHT OR COLLAPSED VALVE LIFTERS
MODELS AFFECTED: 1984-85 MODELS WITH 3.0L (VIN CODES E & L) AND 3.8L (VIN CODES A, 3 & 4) V-6 ENGINES
Some vehicles may experience an intermittent oil light, usually when engine is first started, or a collapsed lifter condition where the cause was not
determined.
These conditions may result from intermittent low oil pressure which may be due to the oil pump pressure regulator valve sticking in the bore.
If this condition is encountered, inspect the valves for free movement of the full bore travel. Assure valve freeness and clean as necessary.
On 1984-85 3.8L and 1984 3.0L engine the valve is located in the oil pump cover.
On 1985 3.0L (VIN Code L) engines the valve is located in the front cover behind the oil filter adapter.
