I have a PD that came in which has a complete failure of the cam and rockers. I need to get a VOA of Castrol TXT to compare to the sample taken from the sump.

No real good pictures yet... The motor is still together at this point. #1 Intake valve lobe COMPLETELY wore thru the lifter top exposing the adjusting piston and groung away on the cam lobe...THE CAR STILL RUNS!
The other lifters (cam followers) all have severe wear and the associated cam lobes have severe micro-pitting damage and deformation.
Ironically, ALL FOUR PD actuator lobes (so far) appear to be in good shape. Easy explanation for that since the PD lobe has a wider lobe and the heavy duty roller rocker.
I will swing by the dealer today and get a bottle of the Castrol and have it sent out to get a VOA.
The owner has had the car serviced completely by VW including all oil changes.
They were getting the run around as to what is wrong with the car leading them to bringing it over to my place. 20 minutes into the diagnosis it was obvious what was wrong...
More to follow as I get it.
