Now I have the car back home and am inspecting the top for damage. So far, the only major wear I've noticed is the Lift cam lobes on the intake side are wiped out badly, and the slipper pads show pretty nasty wear. I wanted to remove the cover for the VVT Acuator to see if there's any damage in there, but the bolts are 5-point???? They look like 10mm, but I don't have any penta-sockets, and want to confirm the size before I go out and buy one.
UPDATE: The failure has been discovered to be a spun #4 rod bearing, the engine has been torn down and is now in the process being cleaned. My current replacement list is as follows:
Intake Rocker Arms
Hollow Head Dowels
Oil Pickup Gasket
Oil Pump Gasket
VVTL Housing Gasket
This thread will now serve as an archive of what to (or maybe what not to do) during a repair of this failure condition. My current goal to get her back up and running is 3 weeks to a month, but that may vary.
