Removal
1. Remove the engine oil pan (see "Oil pan - removal, gasket replacement and installation").
2. Using a 10 mm wrench, unscrew the two bolts 1 securing the oil intake to the main bearing cover and bolt 2 securing the oil receiver to the oil pump housing.
3. Remove the oil intake, removing its tube from the oil pump channel.
Note: The connection between the oil intake and the pump is sealed with a rubber ring.
Installation
We install the oil intake in the reverse order, having first replaced the damaged or loose sealing ring.

Warning! The bolt that secures the oil pickup to the oil pump is longer than the bolts that secure the oil pickup to the main bearing cap.
