Most likely not unless it floats on oil. The Vanos/timing chain area is a straight shot to the front recess of the pan.
The oil pump is a two stage scavenged pump. The scavenged part pulls oil from the front of the pan (there is a screen on the inlet) and pumps this through the small tube into the upper portion of the rear of the pan. The rectangular cutout allows the oil to drain into the sump. The other part of the pump has it's pickup in the sump (the large diameter pipe in the picture) and that end is inserted into the cone screen... Also oil falling from the crank, rods and piston cooling orifices drain into the sump through that rectangular opening to the sump.
A pretty ingenuous design to ensure you ALWAYS have oil to the pump.
No way anything larger than a 1/16" of an inch will get into the pump on either end.
