Such an easy check can prevent your Ford Falcon turbo failing.
There is an inline filter in the oil supply pipe to the turbo in a Ford Falcon (located in the fitting which screws into the block).
This filter is often forgotten about during servicing of the vehicle.
If it is not regularly checked / cleaned / replaced it can block up, restricting oil flow to the turbocharger which will inevitably lead to premature turbocharger failure from insufficient lubrication to the bearing cage.
The inline filter is a genuine Ford part and can be sourced from your local Ford dealer.
The genuine Part number for the turbo inline filter in a falcon BA / BF is : SY9P424A
