Spark plug and coil change @ 100k on 2008 335i...one anomaly

AndyW · 02-21-2015, 08:30 PM

OK, so this is the second time I've replaced the spark plugs. Last time was at 75k and didn't notice anything unusual then. This time went pretty textbook but I noticed something unusual on the plugs. All were mostly dry except the plug from #2 cylinder which was slightly wet what appeared to be oil, and darker on the threads and tip. Now, my car doesn't use oil and I haven't had any other issues that I have noticed. Does anyone have any idea if this indicates a problem I should address with #2 cylinder? Thx. Pic attached.

Is it just the pic, or is #2 plug missing its crush washer?

Either way, I think I've read of possible hairline cracks in the valve cover leading to oil dribbling into the plug orifice.

To me it does look there is a washer, just flush against the plug.

Thx. Yes, there is a washer. Valve cover crack...man, with all that fuel and electric lines routing over the top that has to be a monster job...
