Oil Pan, Remove and Install  

  Remove, Disconnect   

For X 25 XE: Detach wiring harness plug for both oxygen sensors. Remove front exhaust pipe.   Disconnect wiring harness plug from dynamic oil level control sensor (1).   Remove oil drain bolt - collect escaping engine oil.   Remove fastening bolts of oil sump (3) from transmission (2), cylinder block and oil pump.   For version with liquid seal: insert suitable wedge tool (spatula with a wedge height of approx. 3 to 5 mm) between oil pan and cylinder block. Cut into silicone sealing compound (grey) in a circular motion with a thin spatula (with cutting edge). Detach oil pan carefully from cylinder block and oil pump.     Important!    Ensure that the sealing surfaces are not damaged by levering movements or by unsuitable tools.

  Clean   

Clean sealing surfaces of oil pan and cylinder head with flat scraper. Clean the oil pan with a lint-free cloth so that no residue remains of the silicone sealing compound (grey). Ensure when cleaning that surfaces are not damaged. Clean oil pan in a washing device and blow out with compressed air. The sealing surfaces must be free of grease and dirt.  

  Inspect   

Check oil pan for plane surfaces  

  Install, Connect   

For version with elastomer moulded gasket: Apply a bead of silicone sealing compound (grey) to joints (1) of oil pump and rear crankshaft bearing cap (2).   Screw in 2 threaded pins (M8) to secure oil pan in cylinder block.   Insert new gasket into groove of oil sump - ensure perfect installation position.   Now apply a 3 mm bead of silicone sealing compound (grey) to inner sealing surface side as shown in Illustration J 0355 (enlargement).     Important!    The application of silicone sealing compound (grey), installation of oil pan and tightening to torque must be performed within 10 minutes.

  Install, Connect   

For version with liquid seal: Apply a bead of silicone sealing compound (grey) to joints (1) of oil pump and rear crankshaft bearing cap (2).   Screw in 2 threaded pins (M8) to secure oil pan in cylinder block.   Now apply an uninterrupted 3 mm bead of silicone sealing compound (grey) at a distance of approx. 3.5 ± 0.5 mm from inner side of oil pan as shown in Illustration J 0622 (enlargement).     Important!    Apply bead contour with greatest precision. The opening diameter of the tube nozzle must be 2.5 mm.   The application of silicone sealing compound (grey), installation of oil pan and tightening to torque must be performed within 10 minutes.

  Clean   

Clean sealing surfaces of cylinder block of engine oil droplets again.  

  Important!   

When positioning oil pan on cylinder block, transmission and oil pump, ensure that the bead contour of oil pan is not damaged by contacting other components.  

  Install, Connect   

Attach oil pan to cylinder block, transmission and oil pump.  

Installation sequence:  

1  Place oil pan on side against transmission casing and in this position press upwards onto cylinder block. Screw in 2 fastening bolts to secure oil pan. Unscrew both threaded pins (to secure oil pan). Screw in loosely all remaining fastening bolts.  

2  Tighten fastening bolts on oil pump and cylinder block in spiral pattern from inside outwards - tightening torque 15 Nm / 11 lbf. ft.  

3  Tighten fastening bolts on transmission casing - tightening torque (M8) 20 Nm / 15 lbf. ft. and (M10) 40 Nm / 30 lbf. ft.  
 

Attach oil drain bolt with new seal ring: tightening torque 10 Nm / 7 lbf. ft. with rubber seal ring, 55 Nm / 41 lbf. ft. with metal seal ring.  

  Install, Connect   

Connect wiring harness plug to dynamic oil level control sensor.  

Install front exhaust pipe with new gaskets - tightening torque 30 Nm / 22 lbf. ft.  

For X 25 XE: Connect wiring harness plug for both oxygen sensors - note correct routing of cables.  

Fill engine oil up to "MAX" at dipstick.  

Notice: 

For version with liquid seal: The engine oil must not be poured in until 15 min. after installing oil pan. The engine must not be started until 30 min. after installing oil pan.
