It's unlikely that there is a freeze plug in that area. The most common sources of coolant leaks on BMW E46 3-Series models are the expansion tank and the radiator. However, there are a few other possibilities that could cause a leak in that area:

1. Heater Core: The heater core is located inside the dashboard and circulates hot coolant to provide heat to the interior of the car. If the heater core is leaking, coolant can drip down onto the motor mount.
2. Coolant Pipe: There is a coolant pipe that runs along the left side of the engine and connects the engine block to the heater core and radiator. If this pipe is corroded or damaged, it can leak coolant onto the motor mount.
3. Head Gasket: A failing head gasket can cause coolant to leak externally from the engine. While this is less common, it's worth checking to see if there are any signs of coolant leaking from the head gasket.

It's recommended to have the coolant system inspected by a qualified mechanic to determine the source of the leak and to make the necessary repairs.

You will have to clarify behind the oil pan. Front of engine towards fan. Rear of engine transmission side. Or above the pan towards engine side. If there is coolant leaking from behind the engine (between the engine and trans) and is not running down from above eg head gasket or hose connection, chances are good that there is a frost plug leaking on the rear of the block.

clean the engine and check where it is coming from. Is it at the front of the rear> do you smell burning oil when you switch off the engine? Clean an area under the engine compartment and see where the oil is dripping from and get back to us. Typical places for leaks are the valve cover gasket, oil filter housing bracket.

common problem is lose drain plug or oil filer cap.Valve cover leak to. raise on lift and clean the engine.start shortly and rechek again.let me know the general location.front back left or right?

Gasket/O-ring bad on the oil fill cap. The fan is throwing it around where you've found the excess.

Hi,

Let's start by telling you how to diagnose the problem.

Most oil leaks are easily located and repaired by visually finding the leak and replacing or repairing the necessary parts. On some occasions a fluid leak may be difficult to locate or repair. The following procedure may help in locating and repairing most leaks.

Finding the Leak

? Identify the fluid, determine whether it is engine oil, automatic transmission fluid, power steering fluid, etc.
? At what location or point is the fluid leaking from? After running the vehicle at normal operating temperature, park the vehicle over a large sheet of paper, After a few minutes, you should be able to ascertain the approximate location of the leak by the drippings on the paper.
? Visually check around the suspected component. Check around all gasket mating surfaces and hoses for leaks. If your car provides engine oil cooling, check the oil lines leading to the radiator. A mirror is useful for finding leaks in areas that are hard to reach. If the leak still cannot be found, it may be necessary to clean the suspected area with a degreaser, steam or spray solvent. Most car washes provide this service or make it possible for you to do it yourself. Clean the area well, then dry the area. Operate the vehicle for several miles at normal operating temperatures and varying speeds. After operating the vehicle , visually check the suspected component. If you still cannot locate the leak, try using the power method.


The Powder Method

? Clean the suspected area.
? Apply an aerosol-type powder, e.g., face powder, to the suspected area.
? Operate the car under normal operating conditions.
? Visually inspect the suspected component. You should be able to trace the leak path over the white powder surface to the source.


Good luck and all the best
