My Ride: 03 BMW 330i
Misfire cylinder #5 & #6

I see some kind of fluid on the heat shield toward the back of the engine. It's not smoking off or anything. I just replaced the valve cover and VC gasket a couple of weeks ago. I'm pretty sure I tighten that gasket down pretty good. Could it possibly be a head gasket leak? Looks like the fluid is slowly evaporating away. Is the head gasket above or below that heat shield? Thanks.

It might just be the residue of burnt oil from before the repair.

I did my vcg maybe a year ago and I just started leaking in the corner too. I think it's your vcg, if it starts to smell when you're idling (when you notice it because the car isn't moving and blowing the smoke away.

Clean up the residue on the mani heat shield and see if it comes back. While waiting for that, you might reread some of the vcg threads...it's not difficult, but evidently there are a number of details that need to be attended to.

I know in one case, someone had snagged something underneath in that corner (sap vac hose or 02 wires I think).

Anyway, clean it up and go from there. VCG is really the only thing ever associated with a leak from where you described.

Yup it was old dirt on dried oil. Cleared the misfire codes and let the car idle for about 40 minutes and no new codes appeared. I have had misfire codes before but none that have triggered the SES light before like today.
