Help needed 2.8 V6
 

Hi guys, cracking car this A8. But one thing I can't seem to sort is oil being pushed passed filler cap. Tried a new cal and still manages to get past. I know cracked breather pipes can cause this. Are these the only pipes, or are there more that are hidden away?

12 and 13 are the only ones, but IIRC the inlet manifold has to come off to get to 13 where it joins 14.

Are the throttle body seals still available? Might whip the inlet manifold off and inspect them all again. The smell is unbearable

They were last time I checked, but the throttle body gaskets are quite expensive IIRC, and there are two.

Throttle Body gasket 2x 078 133 073B
Inlet manifold gasket 2x 078 129 717J
Inlet manifold guide pin 2x 078 103 251
