How do I get the Distributor Cap off?

[Danbot]

I have a 1989 325i. I think the dizzy is on its way out, but I need to get into it to check the rotor etc. How do I go about getting the distributor cap off, and what do I look for when I'm eventualy in there?

Any help appreciated.

I think there are three screws on the outside of the cap. Loosen those, should come right off.

yeah, it's really easy. clean the points with contact cleaner.

Look for crusty build up on the 6 outside terminals, check and see if the carbon center isn't flat and still springs back out when pushed wipe out the cap with a clean rag to remove and carbon dust. On rotor look for build up and pitted parts along the edge, then make sure that there isn't too much carbon dust collected around the center, this carbon dust can cause the spark to go elsewhere more so during wet conditions.

BTW, there are no points, other than the cap and rotor there is nothing else igniton related in there..
