V10 TDI 2003, OIL LEAK. IT'S NOT TANDEM PUMP? /With pictures/

jurgis331 · Oct 15, 2021

I got a heavy oil leak in the front of the car.
I've read several topics on tandem pump leak, but it looks like this isn't the case.
At first monument its looks like leak is starting at the top middle
I don't know where to start, where to look for the cause of the leak, because the oil is all over the front.

Before disassembly, everything was washed with a high-pressure washer and driven for a while.

Maybe someone has had a similar problem, or just a suggestion on where to start?

If the oil is leaking from the V it is most likely leaking between the oil cooler and oil filter housing. Those o-rings get brittle.

Another source in the V is the shaft seal on the alternator shaft.
