Backstory. So since i got my M3 its had this annoying noise at about 1800rpm when accelerating under load. It only happened when the oil temp was over 90c, and only when under load. It wasn’t vanos, because it persisted after i rebuilt that. The car also made a similar noise occasionally on cold start.
So, the parts arrived today, all the way from Germany. Woot.
Since the vanos unit was done, I moved onto the anti-rattle kit.
The bolt looks a lot different to the photos in the previous page now, it’s got a couple of notches cut in it from a chisel but still wont spin.
It’s now packed with JB Weld. Lets see what happens.
Right, so today was also a story of ups and downs.
This is a guide based on my experience of rebuilding an S50B30 vanos using the Beisan System kit.
These are one of those things that you tend to forget about, but changing the old and worn out ones for new ones can do wonders to uplift the interior. Its cheap and easy.
