hey, im in the uk, I have the baby brother of the 535i, the 530i (6cyl) and its started to smoke on startup after its been sitting for more than a couple of days, its bluey smoke, and lasts for about 3-4 serconds after ignition. Also, it takes a few turns to start up. As long as its in daily use, and bar any of the described problems its still silky smooth and all fluids/idle etc are fine. (also to note it drops a very small amount of oil, nothing to worry about i dont think). It also doesn't smoke at all apart from this, ie, no smoke on acceleration etc.

Ive been told this is the beggining of worn vavle seals. My question is, is this a serious issue, ie., is this neccessarily going to get worse, and how much, excluding parts, would i be looking at to have the head of, reconditioned tec, and this fixed, in uk prices (not main dealer obviously)

ANY ADVICE MUCH APPRECIATED!!
