Oil / where comes it from ?

It doesn`t drop on the garage gulv...but don`t know where it comes from !

 

[Daheim111]

My own guess: the rear crankshaft seal...but all the time no loss of engine oil when I check(ed) it...

I would clean it all off first with a spray solvent, mine was the vent at the top for the PTU, Ford said the hose on mine came off and it made a mess at the bottom of the drivetrain

@reserved50: may be !!! Thank you !

Service manual shows that hose / may be, may be...now I know where I have to search...

And here is the Ford service procedure:

Not that hose...
They say it is may be the bolt (pile on my Pictures) who leads oil out...we have cleaned the whole area twice...but after 1000 km (620 miles) highway on last weekend I can feel a littlebit clean oil on my fingers when touching the area around that bolt...
What kind of oil I can await above this bolt ? 1 Engine oil only when the crankshaft seal is bad / 2 trans fluid has red colour (not colourless)...?

its not leaking from the top? Not sure what the bolt goes into from the picture, maybe a picture from the side it might be easier to see. Its rare to have the engine crankshaft leak

 

[Daheim111]

This bolt and more bolts fasten the automatic transmission case to the engine case / directly on top of this bolt is the crankshaft seal...
It means that there is regularly no fluid or oil to find...but the oil I found (now after cleaning the area and 1000 km driving on weekend / 500 to North Sea and next day 500 south) on my finger is both not black (engine) or red (AT)...

 

[Daheim111]

Today nearly the same...will take the car to the dealer tomorrow...

 

[Daheim111]

Inspected the underbody today and found it in the manual...it is the left bolt near the plastic cap that covers the flex plate...but the flex plate house was complete (!) free of water, oil or others... It seems to be a oily fluid, not really black, not brown, nearly clear...
Removed that bolt / no oil, either on the bolt or in the hole...

It means, that I have no leak from AT or crankshaft seal ! Very god ! But: where it comes from ? Who have an idea ???
