OIL DIPSTICK OR FILL CAP (1.6L EXCEPT EFI) - WHITE-BROWN COLORED RESIDUE - EXTERNAL VENT INSTALLATION


FORD 1983-85 ESCORT, EXP

LINCOLN-MERCURY 1983 LN7; 1983-85 LYNX

A white-brown colored substance may collect on the oil dipstick or inside the fill cap during operation in long periods of extremely cold temperatures with no loss of engine coolant. This condition is due to the accumulation of moisture condensation within the crankcase vent system and may be serviced on 1.6L engines (except EFI) by installing an external vent system using the following procedure:

1. Remove and discard the rocker cover and gasket.

Figure 6 - Drain Vent Tubes:

2. Remove and discard the three internal drain vent tubes located in the cylinder head drain-back holes. The tubes can easily be removed using needle nose pliers without removing the head from the engine block assembly. Bend the tubes around the valve springs to remove them from the cylinder (Figure 6).

Figure 7 - Cup-Plug:

3. Install the new rocker cover and gasket. Tighten bolts to 8-11 N-m.

4. Remove and discard the existing cap-plug located at the left rear upper corner of the engine block and install the crankcase vent tube (part number E1FZ- 6767-B). Apply a coating of pipe sealant (part number D8AZ-19554-A) on the outside surface of the tube before pressing into the block (Figure 7).

Figure 8 - Crankcase Closure Hose:

5. Install the crankcase closure hose and clamps to the two tubes as shown (Figure 8). Tighten clamps to 1.25-2.25 N-m.
6. Clean the white-brown residue from the oil dipstick and oil fill cap.

A Technical Service Bulletin will be published on 1.6L EFI engines upon part availability.
