Just got my car back from the dealer. It runs much better now that the VANOS is back into alignment. The parts required for the lifters were;
12 11-33-7-605-330 Hydr. Valve Pushrod
1 11-12-7-581-215 Profile Gasket
1 11-12-0-409-288 Set of Alu. Screws
2 11-36-7-524-954 Collar Screw
Now that the VANOS is back in line, the MPG has increased by 5 MPG in the city, I'll be interested to see how it does on the highway.
