In this post "today = today + last weekend"
Last weekend I went about updating the VANOS seals using the X8R kit. Ran into a couple of problems along the way.
Firstly, I accidentally rounded the hex bolt/plug that covers the left hand thread bolts on the outside of the VANOS unit. I think it happened because with the limited space I didn't quite have the hex bit fully inserted in the bolt. I tried forcing in a larger Torx bit but that just cut through and turned in the bolt. I started to undo the entire front end (crash bar and front cross brace) as I thought I would have to get a drill on it. Fortunately after I loosened the front end and got a bit more space I hammered the original hex bit back in and managed to crack off the bolt.
Second issue was when putting everything back together I couldn't find for the life of me one of the nuts for the cylinder head cover. A quick visit to ebay and a few days wait and I had everything back together.
While I had the engine in pieces I changed the spark plugs for some NGK Iridium ones. Originals didn't look too bad considering they had about 5 track days on them.
I also swapped over a set of the black backed headlights I bought from a forum member a while ago. I much prefer the look of these ones, especially on a titanium silver Z4.
Fast forward to today, I changed my front caliper brackets (k-system.pro) to allow for the much better 28mm thick 2-piece OEM M3 discs. I then installed the shiny new discs. Hopefully these wont warp on track like the cheap MTEC ones did. It has been so warm today that I even had to put up an umbrella to provide a bit of shade! 8)
Excuse the dirtiness of the car and calipers.
