OCT Fell and Failed

Experiencing power drop during cruising but not during acceleration, not often. Until one time, idling bouncing between 1k rpm to 1.5k rpm. Aron decide to pop the hood to find out the culprit. 

And he saw the oil catch tank fell off from the bracket...

Power drop caused by the oil catch tank hose touching the pulley and make it slow.

Bouncing idling caused by vacuum leak.

Source for a new oil catch tank.

Installed.

Problem solved.
