A6 2.5TDI front crankshaft seal leaking


Registered User
Anyone think of any reasons why the front crankshaft oil seal would start leaking badly. The breather between the cylinder banks was checked and is clear so I don't think pressurisation of the sump is the problem unless anyone can think of any other cause? I recently had the belts, tensioners and water pump changed and the leak has started since then.
