I have made this guide to aid anyone else that is undertaking this work, and to supplement the Beisan Systems instructions, as they are based off the S50B32 engine and is lacking some detail and crucial information. The Beisan instructions are here, http://www.beisansystems.com/procedures/euro_s50_single_vanos_procedure.htm DISCLAIMER: THIS IS MY EXPERIENCES WITH THIS. THIS IS NOT A STEP BY STEP INSTRUCTION, IT IS MEANT TO COMPLIMENT THE BEISAN INSTRUCTIONS TO FILL THE GAPS AND HIGHLIGHT DIFFERENCES BETWEEN THE 3.2 AND 3.0. PLEASE FOLLOW AT YOUR OWN RISK. The first step was to make sure i had all the tools that Beisan lists. The list they supply is pretty good. MAKE SURE YOUR TOOLS ARE GOOD QUALITY, ESPECIALLY YOUR HEX SOCKETS OR YOU WILL STRIP BOLTS. First step, remove fan and shroud. First issue i had.... 32mm wrench is too big to fit between the fan and water pump bolts. Solution, remove two of the bolts in the pulley. A swift whack of the hammer on the spanner and off the fan comes. Fan is on a reverse thread. Remove the shroud with the fan. Important to keep organised. Next up, remove the coil cover and disconnect all the coils. Move the coil wiring out of the way. Pull the coils out. Remove the valve cover. My gasket is hard and like plastic. Beisan says that the gasket is Viton and does not require replacement. I would HIGLY recommend having a replacement before starting work. Finding Top Dead Center. The Beisan instructions say to line up a pointer like the below one, with marks on the front of the harmonic balancer. After 2 hours of searching and much frustration i finally worked it out. By fluke i found the pointer, a simple mark on the timing cover, and the marks on the balancer arent on the front, but hidden down behind the pulley. Beisan says the solenoids will be linked, and removed in a certain way. Nope, in the 3.0 they are separate and the wiring doesnt exit via the bottom like the 3.2, it exits top and bottom, per solenoid. The top solenoid wiring is also spiral bound to the cam sensor on the vanos bridge, so that needs to be removed before the solenoid comes out. This is the intake piston nut. Its tiny, are this has been the cause of many issues for others. IT IS NOT REVERSE THREADED, LEFTY LOOSEY, RIGHTY TIGHTY. It wont be very tight.
