I don't think so. The oil cooler is separate from the cooling system. Most likely have a blown gasket or cracked block

BMW E46 318i Fuel consumption problem it is apparently using 1 mile of fuel every 100 meters. BMW E46 318i


Could be many things, but fuel pressure regulator, leaking injectors are most likely. DO NOT DRIVE UNTIL FIXED. If the fuel is really getting into the oil pan, oil will be diluted and could damage engine bearings.

4)engine oil being blown ut past the intake manifold gasket
5)punctured automatic transmission modulator diaphragm
6)oil viscosity is too low.

My 2002 BMW 318i e46 oil pressure light goes off with start up and comes back on after a few seconds and stays on for 90 seconds -can any body help please( the car has done 350000 km


The VERY 1ST thing you need done here is to have a mechanical test gauge hooked up to the engine and verify the oil pressure is ok, then if it is replace the oil pressure sending unit on the engine. Do not drive this until you are sure the pressure is good, you can quickly burn up the bearings and ruin a very expensive engine.
