Oil pump
The gap between the teeth of the gears of the oil pump, mm: 0.10-0.20.
Clearance between the ends of the gears and the plane of the pump housing, mm:
- engines «13N», «13S», «14NV», «16SV», «C16NZ»: 0,08-0,15;
- other engines: 0.03-0.10.
Oil pressure at idle, warm engine (oil temperature 80°C), not less than, kg/cm2: 1,5.
Oil filter
Oil filter - full-flow, with a replaceable filter element. The filter is connected in series to the main oil line of the engine directly after the oil pump.
Brand and type of oil filter:
- engines «13N», «13S»: AC Delco type SD, thread 3/4*;
- other engines: AC Delco type X93, thread 18x1.5 mm.
*Before September 1985. From this time on, the same oil filter is used as on other engines.
