300 tdi massive oil leak! ideas?

today when I checked my oil I noticed huge amounts of oil basically all over the engine. It looks to be from the front cover area, at least the fan blades and pulleys all have oil on them. Also the top radiator hose and the thermostat housing had oil that looked like it had been slung onto them. It was even on the hood insulation and as far back as the fuel filter and washer reservoir. Of course it needs to be fixed but has anyone seen something similar. Any suggestions as to where to start looking. Seems like it leaked out about two qts or more in about 60 -70 miles of hwy driving.
thanks for any help.

Could possibly be a oil cooler line where it attaches to the radiator. or you could possibly have a front crankshaft seal or cam seal that has failed and seeped through the timing cover seal. It doesnt take much of an oil leak to go everywhere once the fan throws it around.

I have not had a chance to check it out in the day light so will check the oil cooler line closely. I guess it could be shooting the oil into the fan.

Mine was the crank seal and it was GUSHING oil.

Eric if it is the crank seal should I also go ahead and change the timeing belt etc? I don't know when it was last changed. The guy I bought it from said eng. was rebuilt 5000 miles before I bought it , but I am having doubts considering the number of oil leaks etc.

If you are in there you might as well belts are cheap and you will have it off to change the seal.

I don't think there should be that much oil coming from the timing cover drain hole.

There should be no oil coming from there.

I am not sure if it was the timing cover drain hole. I did not see what he replaced. Is there another screw in type plug on the lower part of the engine? maybe near the oil pan? I need to get it on a lift and check it out first hand. obviously I am not handy with a spanner, so need to check into this drain plug deal. thanks for the info.
