J 45299 Engine Preluber. See Special Tools .

  1. Remove the engine oil filter, fill with clean engine oil, and reinstall. Tighten: Tighten the oil filter to 30 N.m (22 lb ft).
  2. Locate the engine oil pressure indicator switch on the left side of the engine and remove.
  3. Install the 1/4 inch adapter P/N 509373.
  4. Install the flexible hose to the adapter and open the valve.
  5. Pump the handle on J 45299 to flow a minimum of 1-2 quarts of engine oil. See «Special Tools»(ref-239708-S25923693292006080100000) . Observe the flow of engine oil through the flexible hose and into the engine assembly.
  6. Close the valve and remove the flexible hose and adapter from the engine.
  7. Install the engine oil pressure indictor switch. Tighten: Tighten the engine oil pressure indictor switch to 16 N.m (12 lb ft).
  8. Top off the engine oil to the proper level.

Scheme 7: General Description

A crankcase ventilation system is used to consume crankcase vapors in the combustion process instead of venting them to atmosphere. Fresh air from the throttle body is supplied to the crankcase, mixed with blow by gases and then passed through a PCV valve into the intake manifold.

Scheme 8: Operation

The primary control is through the positive crankcase ventilation (PCV) valve which meters the flow at a rate depending on inlet vacuum. To maintain idle quality, the PCV valve restricts the flow when inlet vacuum is high. If abnormal operating conditions arise, the system is designed to allow excessive amounts of blow by gases to back flow through the crankcase vent into the throttle body to be consumed by normal combustion.
