Default Oil warning light

Yesterday I finally started filling the car with coulant and oil.
I'm sure that I filled about 7 liters of oil. Oil filter was replaced as well so I've filled what the WSM said it would take. The level is ok on the dipstick.
Despite all, my oil warning light keeps flashing. In my resto process I've changes the oil pressure sensor, could this be cause of the flashing light.
What am I missing? The car is running perfect as I take it around the block.

The oil pressure warning light? What is the indicated oil pressure on the gauge?

Has the warning light been flashing ever since you installed the new pressure sensor? If so, you may have reversed the wires when installing it.

Indeed I'd reversed the wiring. Problem solved.
Still pegged at 5 though. I'll worry about that later
Thanx for the tips guy's.

It will peg at 5 until the engine warms up.

Last weekend during an oil change I've found out why the oil level warning light kept flashing. The front weel of the oil level sender is laying loosse in the oil pan.




I've removed the 30 bolts of the oil pan but wasn't able to drop it. This weekend I'll drop the oil pan with this method.

Any problems I'd might have to tackle?

if you have the pan loose and the oil sender is removed then yo0u should be able to fish the remaining parts out of the pan with a coat hanger .

\ Its worth a try as removing the pan requires lots of work and if you go that far you should replace the motor mounts and the pan gasket

The only option is to remove the pan. Some maintenance has to be done to it.
The thread for the drainplug is damaged and the surrounding outside area near the drainplug hole has a dent, causing a minor leak.
