Service Procedure

SERVICE PROCEDURE

This recall will involve inspection of the turbo charger oil supply pipe for proper alignment including checking for possible stress cracks and/or oil leaks. If the pipe is found to be properly aligned and there are no signs of cracks or oil leaks, a pipe stay bracket used to check pipe alignment will remain installed as a precautionary measure to increase rigidity of the pipe. If the pipe is found to be misaligned, cracked or leaking oil, a new replacement pipe must be installed.

The number of affected vehicles produced with a misaligned and deformed turbo charger oil supply pipe is expected to be low. Replacement of the oil supply pipe will only be necessary when indicated by the inspection results described in the following Inspection Procedure.

Note:
Do not replace the turbo charger oil supply pipe unless specifically instructed to do so while following the inspection procedure.

Inspection Procedure





1) Identify the location of the applicable turbo charger oil supply pipe as illustrated in Figure 1, above.





2) Visually check the pipe for signs of cracking and/or oil leakage in the area of the pipe identified in Figure 2, above.

^ If the pipe shows signs of cracking and/or oil leakage, replace the pipe and related parts using part number 15192AA512KAI - Pipe Kit - Oil. Skip Step 3, and proceed to the "Turbo Charger Oil Supply Pipe Replacement Procedure" shown in this service procedure.

^ If there are no signs of cracking and/or leakage, proceed to Step 3.e, proceed to Step 3.

3) In order to determine alignment of the turbo charger oil supply pipe, it will be necessary to install a pipe stay bracket with clip and rocker cover bolt. Part number 24012AA010 - Stay Set.

CAUTION:
The pipe stay bracket must be installed correctly as instructed in the following steps "a" through "d". Otherwise, it will not be possible to determine the correct measurements.





(a) Remove the original rocker cover bolt which is located at the upper rear of the RH side of engine. (See Figure 3)





(b) With the plastic clip attached to the pipe stay bracket, insert the plastic clip firmly onto the pipe beneath the pipe flare nut as illustrated in Figure 4.

(c) Be sure to use the new rocker cover bolt contained in the "stay set" kit when installing the stay bracket. The new style bolt is longer then the original and has no carved seal on the head of the bolt.





Caution:
Do Not Reuse The Original Bolt. However, do not discard the bolt at this time. (See Figure 5)





(d) Attach the pipe stay bracket to the engine using the new rocker cover bolt as illustrated in Figure 6. Tightening torque: 6.4 +/- 0.5 N-m (0.65 kgf-m, 4.7 ft-lb).











(e) Referring to the measurements defined in Figure 7 above, make a visual inspection to determine if the pipe is properly seated in the pipe stay bracket clip. Check the 4 reference points "A" through "D". Refer to the corresponding photographs above for visual confirmation. During this process, a "GO" or "NG" (No Go) condition will be determined for each of the 4 reference points ("A" through "D").

^ If all 4 reference points are within the "GO" range, the inspection is complete and no further action is required.

^ If any of the reference points are found to be in the "NG" range, replace the pipe.

Refer to the Turbo Charger Oil Supply Pipe Replacement Procedure, shown below.

TURBO CHARGER OIL SUPPLY PIPE REPLACEMENT PROCEDURE

Important:
If the Stay Set was previously installed, remove the pipe stay bracket with clip and rocker cover bolt prior to replacing the pipe. Be sure to use the original rocker cover bolt when replacing the pipe. Discard the pipe stay bracket with clip and rocker cover bolt. Do not reuse these parts on another vehicle.

If it has been determined that the turbo charger oil supply pipe requires replacement, replace the pipe and related parts using part number 15192AA512KAI - Pipe Kit - Oil. This part is a kit and contains all necessary gaskets and seals to perform the repair. Although no specific instructions for replacement of the turbo charger oil supply pipe are listed in the Service Manuals, follow the procedure for removal and reinstallation of the intake manifold found in the applicable Service Manual. After removal of the intake manifold, replace the oil supply pipe.




Note:
For vehicles that have been in service, prior to installing the oil pipe banjo bolt, inspect the mesh screen for debris. Clean or replace as necessary. Use the torque specifications shown above for proper pipe installation.

Important:
Do not install the Stay Set Part number 24012AA010 when the new style pipe is installed.
