Hi
When i checked the oil level on the engine on my MPI Cooper today i saw that there was some brown dust on one of the spark plugs. One of the ignition leads had also brown dust inside it.

What could it be? I am thinking that it might have something to do with a little leak from the rocker cover, but i might be totally wrong

By the way - the Mini is driving great as always

Corrostion of the internal contact of the HT leads. My opinion - clean out an remaining dust from hte ht lead cap, then replace the HT leads and spark plugs when next doing oil service.
