Engine oil gas line and intake manifold

[203132]

Hi Guys,

We've had the engine light on since January and after going back repeatedly, last month we replaced the oil separator that was blocked. Only recently, we have an a rough idle, EPC light and engine light on, the car went into limp mode and now we have to replace the intake manifold.

Are these 2 parts related during the repair process? I am asking because the time between the repair and the intake manifold issue was only weeks apart.

Are they related at all if one part fails?

Two seperate faults.
