Did Megan have aftermarket pulleys? Last night I went through threads with other damaged VQs and found this to be a potentially contributing reoccurring common link.

After I talked an extended period of time over the phone last night.
No, the pulley doesnt seem to be part of the problem since its not the oil pump that failed first.

the damage first happenned in the VVEL head .
I drove back home, which is normaly a 6 hours drive, with a quite noisy VVEL head but 200 kms later, it lost 90% of the power and barely made it to the next exit. once the engined died to 0 rpm , it never wanted to rotate (broken oil pump and VVEL head.)

that mysterious pin is probably what caused to fail the oil pump .. it was probably stuck somewhere that restricted the oil flow in the head

next,
my last finding that the camshaft sprocket was loose is surely one of the big problem.
