crankshaft back seal leak oil

[golfrr]

Car of the VW Touran 2.0TDI 103kW DSG 2005, which is leaking from the engine crankshaft oil seal at the rear end. The strip has already been changed 3 times over and over again, however, the seal between the engine begins to run out of oil. Anywhere else in the engine oil does not come off. Change is the engine head cover. Can anybody give advice as to what to do.

You must have blocked breathers somewhere. She will just keep blowing seals if you dont clear them.

Only breathe is on the head cover and this is new. What opportunities have?

Too much back pressure, bad and very "butchery way" out of it would be to drill small breather holes in oil cap. Might blow oil out of it still at that. Is your crankseal still leaking ? Maybe there is a groove worn into the crank itself ? No seal will repair it
