Freeze plug w/ oil in it?
Changing a coil the other day I noticed these reservoirs next to each, which I discovered are freeze plugs. Most had a small bit of loose dirt and one had oil in it. Any ideas why this would occur?

Probably a leaking valve cover. Very common problem. It could be the gasket or a crack in the cover. Both are quite common.

Thanks for the reply. Could you elaborate on the level of probability? Have you seen valve cover leaks result in a bit of oil in the freeze plugs?

I had to replace mine at 47K and it was a bone stock vehicle driven by a mother of 1. My advice is to clean the cover and area and inspect after a few days. You'll either find the crack in valve cover after it's been cleaned or figure out the problem area one way or another after it's been cleaned and re-inspected after some miles. |

Mine was partial slush in middle. Lol
I've went with the clean and check later method here at 101k, but this summer valve cover and valve seals go. At least a bank of injectors comes sooner once rock auto has them in stock. |

See that little cap like thingy with that rubber shield under it in the upper part of the picture? I believe it says "BMW OIL" on it. See how there's this slick filmy stuff all around it? Guess what that is...oil, right? Now look where you're questioning. Still questioning?

So maybe during an oil change oil could have gotten into the spark plug wells ?

Step 1: Clean up oil mess
Step 2: Drive for 2-3 days and monitor that area for more oil Step 3: If there is oil back in the valve cover area, most likely valve cover/Gasket. |

If you are unsure about it, get it done by a pro. I see you are in NJ. I recommend Auto Cotour Motoring in Fairlawn. Tell them I sent you. |

Its a relatively easy job. Can be tedious if the gasket doesn't want to stay in the valve cover when installing. |
