It sounds like your spark plugs were fouled. Does it keep happening? If so, you may have low compression and oil is blowing through. If it only happened that one time then I wouldn't worry about it. It happens after a while.

Spark plugs is soot black and there's a check engine msg after oil spilled on the engine when i forgot to cover cyclinder head oil cover


the black soot may be old plug wires that should be replaced chances are the spilled oil caused the engine to miss fire setting off the check engine check the inside of the plug boots and plugs for oil.

How do I change the spark plugs on a BMW 523i engine and what is the correct spark gap?


The spark plug change is very straight forward. Basically, you remove the plastic valve cover trim panel, unplug the harness plugs from each of the ignition coils, remove the two nuts securing each coil, pull the coil up. The rubber spark plug connector boot should come up with the coil. You can now remove the spark plugs.

The spark plugs are not gappable. Install them as they come out of the box.

Replace the rubber connector boots at the same time, these wear out and can cause miss-fire problems.

Note that if you find oil in the spark plug wells, the valve cover gaskets must be replaced. Not only does this make a mess, but it deteriorates the boots and also causes miss-fires.

See the DIY article in the Spring 2005 issue of the Bavarian Autosport - Fast Times newsletter (see link below):

Contact Bavarian Autosport for the spark plugs and connector boots (and valve cover gaskets) at 800-535-2002, or order online.

Miss firing engine and black spark plug


Is it a two stroke machine , do you mix your own fuel.

If so over dosing on the oil component will cause your problem, check for the right mix levels and follow them.

Is the choke going full back to zero ?

Are you running the right type pf plug for that engine, some run hot some dont

Is the engine running smooth or lumpy.
====================================================================
For a four stroke engine

Your engine may either be running very rich or there is wear on the bores causing oil to get to the electrode.

You can obtain a spark plug extender which takes the plug out of the direct line of fire

Oil in the spark plug tubes. engine misses when at an idle.


You probably have a leaking valve cover gasket causing the leaking oil to collect in the spark plug tubes.
The miss fire is probably caused by the HT in the plug lead shorting through the oil and causing a weak spark.
Clean all the oil out and track down the leak.
