I went and saw everything Raj does at beisan systems, how he came up with the fix and all the new stuff he is working on. His seal kit is only $30 and makes a world of difference, he also offer an anti rattle kit that is another $30. $60 for a rebuilt vanos unit is a damn good deal. |
I'm pretty sure I met Raj at Bimmerfest last year. If it's the same guy, he had a booth set up and was showing me the seal kit and anti rattle bushings that he designed. However, the VANOS rebuild as he demonstrated was really easy and takes less than half an hour aside from the actual time it takes to remove/reinstall the VANOS and set the timing. Besides the timing tools, the only thing necessary was some nylon covers to place over the ends of your vise to prevent marring the aluminum Vanos housing. What I was getting at was that bad(flat/hardened) seals don't necessarly render the VANOS useless. BMW engineered it for a reason and they continue to use it because it works well.
