Changed oil in bmw e36 now spark plug socket and spark plug are showing engine oil (old) Shop gave me wrong oil filter so have not started car yet as I do not have the right filter Also I changed air

IF there is a sleeve around the spark plugs then when replacing the plugs replace the seal under that sleave as well or rocker cover oil will leak out past the plug base.. If you want the correct oil filter you may have to buy genuine . Run fault codes to find the reason for rough idle . It may be a vacuum hose is off or cracked or loose.

Oil on the spark plugs/failing cylinder?

The important question is - oil on the top half of the spark plug, or oil on the bottom (fire) end of the spark plug?
Oil on the top end of the plug means that your valve cover gasket is leaking. This is a common problem. BMW valve cover gaskets get hard and shrink and have to be replaced about every 10 years. It is an easy do-it-yourself repair, but it can take a while to dig the old hardened gasket out of the valve cover without scratching it. Just be patient.
If the bottom (fire) end of the plug is wet, either the plug is not firing due to a failed coil or some other electrical problem, or you have bigger problems in that cylinder. A compression test is in order.

First there was occasional white smoke, loud engine rattle, cutting out on full throttle and poor starting. the injectors were serviced but the engine has refused to start.

White smoke is usually an indication of a blown head gasket. Check you oil (dipstick) for a milky looking color instead of normal oil. Pull a spark plug and look to see if there's moisture on it. All of the symptoms you've given point towards a bad head gasket

2001 5 series spark plugs are getting flooded with oil making my engine misfire why and what can i do too fix it

Well, the key question is how much oil are you consuming...Quart in 600 miles or more is considered normal, but I prefer 1 quart in 2500 miles...

If high oil consumption, consider hotter plugs, and decide if engine work makes sense. If only a cylinder or two, try hotter plugs in those cylinders

If no oil consumption, look to weak spark, damaged wires, etc.

You need to remove the top cover 1st. Then remove the gray trim covers on the left and right banks by pulling straight up.You will find individual coils in each cylinder. Disconnect the connector of the coil and pull the coil straight up.The plugs are under each coil.

1998 BMW Z3 1.9 Cylinder misfire codes. Rough on cold wet starts

Spark plug wires may be the cause. for cold damp start issues water is a conducter and will send spark directly to an engine ground not through spark plugs. also look for oil in spark plug wells this can also cause a misfire under certain conditions.
