2000 Dodge Intrepid Oil light blinks

Hello sebastian_personal

Change oil, oil filter and oil screen(because of 160000 miles)
use synthetic oil because 2.7 is well known for oil sludge problem, and synthetic will be good for that engine.

If it does not take care of the problem, Raise vehicle on a suitable hoist.
(This bulletin involves adding a terminal/wire/vent to the oil pressure switch connector)
Remove engine oil pressure switch connector from switch.
Remove sealing dart from the empty cavity at the rear of the connector.
Pull terminal locking ring outward from front (switch) side of connector to gain access to terminal locking tabs.
Install wire terminal/vent, p/n 05017800AA, in place of the removed sealing dart. Slide locking ring back into place.
Attach the connector back on the oil pressure switch.
Spot tape the wire/vent to follow the harness towards the top of the engine compartment.
(this should take care of the blinking oil light)

Remove the oil pan, you will need a new gasket.
it is the screen at the end the pick up tube.
it is good replacing the whole pick up tube if screen is plug.
