BMW X5 4.4 Oil in spark plug?
the valve cover gaskets got replace. But now I
notice the oil is in the bottom of the spark
plug..could that mean something serious?
If you recently had the gaskets replaced because they were leaking, I can only assume some il migrated into the spark plug wells. Whoever replaced the valve cover didn't take the time to clean the area before reinstalling. Soak up the oil as best you can and watch the area if it gets worse.
I did all of that. I clean all of the oil that was inside and I even blow it out...
Update I redo the cable cover gasket found no oil at all...the misfire is still there. I even check for oms and volt on both injector and ignition coil good..the coil also get a signal from the ECU...how do I check the wire for the ECU to make sure the coil is getting the signal
