Boxster Engine Fault

[Guest]

I am looking for information on a boxster 2.7 2002 model which has excessive oil burning & oil in the inlet manifold. I have now removed the engine and stripped as the whole engine was contaminated with oil, i realise that this is probably the aos valve.
On removing the sump, there appears to be the coil part of many oil seals jammed in the oil pick up pipe.

I am also looking for the torque settings for the cylinder head bolts

I would appreciate any information or help anybody can give..thanks
