Recall: Crankcase Ventilation Check Valve Sticks
MI No. 291-2217 ed. 2PI NO.
Date: June 2000
Distr. US, CA, JP
Recall 719: Replacement of check valve and banjo bolt
Background
Affected cars have two faults that could eventually affect emission control:
^ The check valve for the crankcase ventilation can stick, pressurizing the crankcase. and forcing engine oil into the combustion chamber.
^ The flow of coolant through the turbo unit may be reduced, which results in the temperature becoming so high that the engine oil crystallizes (builds carbon deposits) around the turbine-side bearing. Over time these deposits reduce the oil flow through the bearing, which means that engine oil is forced past the turbine shaft seal and out into the exhaust pipe.
This MI describes the procedure for preventing excessive emissions and damage to the turbo unit.
Cars affected
All Saab 9-3 with 4-cylinder engines within the following VIN Serial No. Ranges:
All Viggens: X7000001 - Y7005097
9-3 3D/5D: Y2000001 - Y2017062

Procedure
Before proceeding, check box B5 of the modification identity plate. If the box is not marked, continue as follows.
Vehicles within VIN Serial No. Ranges:
All Viggens: X7000001 - Y7003737
9-3 3D/5D: Y2000001 - VIN Y2013566
9-3 CV: Y7000001 - Y7003737
All steps must be carried out.
Vehicles within VIN Serial No. Ranges:
9-3 30/5D: Y2013567 - Y2017062
All Viggens: Y7003738 - Y7005097
9-3 CV: Y7003738 - Y7005097
*Perform steps 1-12 only. *
1 Remove the engine cover.
2 Cut off the cable tie securing the check valve to the valve cover.
3 Detach the vacuum hose from the valve cover and the throttle body.
4 Transfer the insulation sleeve from the old hose to the new.
5 Attach the new hose to the valve cover nipple and to the throttle body.
Important
The check valve should be turned so that the flow is directed from the valve cover to the throttle body, see the arrow on the check valve.
Fasten the non-return valve to the valve cover using a cable tie.
*6 Check that the ignition key is in the OFF position.
7 Remove the screw for the turbocharger delivery pipe's mounting to the throttle body.
8 Remove the turbocharger delivery pipe from the throttle body and turn back the pipe. Take care with the O-ring.
9 Turn the throttle body to the open position. Clean and dry the inside of the throttle body, especially around the outer sealing edge of the throttle plate. Use a lint- free cloth moistened with electronics cleaner safe for use with oxygen sensors.
10 Lubricate the O-ring with acid-free petroleum jelly and mount the turbocharger delivery pipe to the throttle body.
11 Refit the screw for the turbocharger delivery pipe's mounting to the engine and the hose clamp at the pipe's mounting to the throttle body.*
12 Fit the engine cover.
13 Open the coolant expansion tank cap to release the overpressure in the cooling system. Close the cap.
WARNING
Exercise care if the car is warm. The coolant is hot and there is also a risk of burning yourself on the manifold.
14 Place a receptacle under the car.
15 Using a open end wrench to hold the coolant pipe nipple in place on the cylinder head, detach the coolant pipe from the cylinder head, see illustration, and the pressure sensor mounting.
16 Check that the coolant pipe nipple on the cylinder head is tightened, and fit the coolant pipe with a new banjo bolt and new gaskets in the cylinder head, see illustration. Fasten the pipe to the pressure sensor mounting.
Important
The banjo bolt 51 25 406 must not be fitted in any other location in the cooling system than in the connection to the cylinder head.
Tightening torque:
Nipple in cylinder head 35 Nm (25.6 lbf ft)
Banjo bolt, cylinder head 25 Nm (16.4 lbf ft)
17 Top up the coolant if necessary.
Stamping the campaign plate
After the car has been inspected and/or modified, mark the campaign plate in position B-5, using a numeral "6" (Saab Special Tool P/N 02 97 713). Order this special tool directly from Kent-Moore at 1-800-345-2233.
