See the valve cover removal procedures in the DIY blog post/video below. Click HERE to view M54 valve cover gasket replacement DIY how-to video. 1) Remove valve cover (see DIY video). 2) Remove the engine fan and shroud. Specific fan shroud removal steps will vary from model to model. The X5 is shown here. See the applicable Bentley repair manual for specific models. Release the two plastic push rivets by pulling the center pins out and then pulling the rivets out. Remove the harness plug from the AUC sensor and pull the auxiliary fan harness plug from the mounting clips. 3 of 18 14-08-13 03:50 PM BMW DIY – Double VANOS Repair (Rebuild) on ... http://blog.bavauto.com/13829/bmw-diy-double-v... Use the special 32mm fan clutch wrench and pulley holder tools to remove the fan from the water pump pulley flange. Position the holder over one of the pulley bolt heads and inset the wrench onto the fan clutch nut. Note that the nut is left-hand thread (the wrench will turn clockwise when viewed from the front of the vehicle). Hit the wrench with a hammer to shock the nut loose. Spin the fan off by hand. Pull the fan and shroud up and out. 4 of 18 14-08-13 03:50 PM BMW DIY – Double VANOS Repair (Rebuild) on ... http://blog.bavauto.com/13829/bmw-diy-double-v... 3) Unplug the various electrical connector plugs from the VANOS solenoids, exhaust camshaft sensor and the thermostat (four in all). There are two connector plugs on the lower passenger side of the VANOS housing (cam sensor and VANOS solenoid), one connector on the rear end of the intake VANOS solenoid and the thermostat electrical connector, just under the driver side of the VANOS housing, at the front. 4) Remove the VANOS oil pressure line from the VANOS solenoid valve housing. This is a banjo type fitting. Remove the bolt and watch for the two sealing washers on either side of the banjo hose end. Use an oil absorbing “Pig Mat” towel to catch any oil drainage. 5) Remove the VANOS piston plug caps. Use a 8mm Allen bit to remove the caps. Additional oil will drain from the housing when the caps are removed. Be prepared with a small container to catch the oil. 5 of 18 14-08-13 03:50 PM BMW DIY – Double VANOS Repair (Rebuild) on ... http://blog.bavauto.com/13829/bmw-diy-double-v... 6) Remove the VANOS piston plugs. Use a small pair of flat-nose pliers to grasp the center rib of the plug and pull it out. Some additional oil will drain. Do this for both intake and exhaust. 7) Remove the VANOS piston securing bolts. NOTE- these bolts are left-hand thread (they turn clockwise to remove). Use a Torx T30 bit to remove both the intake and exhaust bolts. 6 of 18 14-08-13 03:50 PM BMW DIY – Double VANOS Repair (Rebuild) on ... http://blog.bavauto.com/13829/bmw-diy-double-v... 8) Remove the engine lifting bracket. Remove the upper nut and lower bolt securing the bracket. 9) Remove the 6 bolts and 1 stud securing the VANOS housing to the cylinder head. 10) Gently pull the VANOS housing forward to remove it from the cylinder head. If the housing is “stuck”, gently tap the intake side oil control valve housing to dislodge it. 7 of 18 14-08-13 03:50 PM BMW DIY – Double VANOS Repair (Rebuild) on ... http://blog.bavauto.com/13829/bmw-diy-double-v... 11) Place the VANOS assembly on the workbench. Using a couple layers of the Pig Mat absorbent mats will help to control the additional oil that will continue to drain from the unit. 12) Remove the 5 bolts securing the intake side VANOS piston cover to the housing and gently pull the cover up and remove it from the housing. The housing will be filled with oil. Hold the piston in place and drain the oil into a container. Once drained, pull the piston out of the housing. 13) Remove the 4 bolts securing the exhaust side VANOS piston cover to the housing and gently pull the cover and piston up and remove it from the housing. Note that there is a moderately strong spring under piston and the piston will be pushed up with the cover. Loosen the bolts in a crisscross pattern, while pushing down on the cover 8 of 18 14-08-13 03:50 PM BMW DIY – Double VANOS Repair (Rebuild) on ... http://blog.bavauto.com/13829/bmw-diy-double-v... to prevent the cover, piston and spring from flying off. Once the bolts are removed, gently allow the spring to push the piston and cover up and remove them. The housing will be filled with oil. Drain the oil into a container. 14) Clean the VANOS housing, pistons and covers with brake parts cleaner or other solvent based cleaners. If the gasket between the VANOS unit and the cylinder head is attached to the VANOS housing, remove it now and clean the mating surface on the housing. 9 of 18 14-08-13 03:50 PM BMW DIY – Double VANOS Repair (Rebuild) on ... http://blog.bavauto.com/13829/bmw-diy-double-v... 15) Note that there are eight new seals in the repair kit; four large and four small. Of these, two large and two small seals are black and noticeably stiffer (and have a square cross-section) and the other four are brown and more pliable (and have a round cross-section).
