Boxster 986 particles in oil filter

Many thanks for that information and the photo - I will study what you said and possibly rethink my plans...Sounds like test of cam deviation is good idea. When yours broke did the engine lights come on?

You're going to want to address this to avoid bigger problems. I got an "S" cheap because the remnants of those guides blocked the oil pickup and shut down the engine.

No clue. Never seen this car run

Its not Camshaft deviation your looking to test if your wanting to see if your Variocam actuators are working.
Its Camshaft advance when the actuator kicks in.
Go up to post #3 in this thread and click on the link. (it says Green Rubber)
Read that entire thread.
There is an explanation of what your looking for in the test and at what RPM.
There is also a brief explanation of Camshaft deviation and what the specs are.

Lots of useful info in that thread. Regarding the deviation: in the 5 chain engine where the camshaft position sensor monitors the intake camshaft only, and the intake camshaft is the one that`s moved by the actuator, so when the solenoid kicks in the deviation should change as well, shouldn`t it? Maybe this is not true for the 3 chain engines.

Not the way I understand camshaft deviation.
Think of the relationship of the camshaft to the crankshaft.
The cam will be timed to the crank.
Lets say the Cam is off by 3 degrees of advance from that set point.
That would be 3 degrees of positive camshaft deviation.
So actuator kicked in or out you will still have 3 degrees of positive camshaft deviation from its proper timing relationship to the crankshaft.
The movement or advance of the cam when the Variocam actuator kicks in is a design feature of the system.
Deviation is not.
That's my current understanding of it.

Yes, Thanks blue62 - I never actually realised the "green rubber" statement was a link I could click on and view (thought it was just a statement of what the particles were or are)
