Let us know

When I removed the plugs, there was no oil anywhere. I didn't inspect closely the valve covers, but I haven't seen any oil stains. The engine is bone dry at the bottoom as well. The only noticeable oilstain was behind the passenger side big cylinder on top of the valve cover (sorry for my ignorance -I don't know what that part is or what it does. There are 2 of them, one on top of each of the valvecovers and look like ahuge condenser). That oilstain was old, a heavy cake of oil & old dust, and was pretty much around an electrical plug, which I think is attached to that cylinder. Maybe an old oil leak around that area?
I think that blue smoke was always coming out when starting the engine cold. it's a distintct heavy smell, which my other BMW doesn't have. And it lasts a few minutes.
Once the engine is warm, there's no problem anymore.
