I just completed many gasket and seal fixes from the oil pan to the head. I have no leaks 😊 but low oil pressure. I confirmed that the sender works, and pressure relief valve works fine. What else can I look for before I have to check the oil pickup? My gauge and a mechanical gauge both read between 2-3 bars. Any suggestions? Thanks!

Did you remove the crank bolt? If so, make sure it's torqued to spec.

Yes torqued to 155 In lbs

"Yes torqued to 155 In lbs"

You do mean "ft lbs" right? If not it is a little too loose!

Yes ft lbs.

The 944's oil pressure should run 4-5 bar at idle when the engine is cold. It will gradually decrease to 2-3 bar at idle as the engine oil warms to normal operating temperature. Once the oil is at normal operating temperature, the oil pressure should indicate around 4 bar at 5,000 rpm. It takes the oil longer to reach its normal operating temperature than the coolant. Therefore, don't be surprised if oil pressure continues to decline after the coolant temperature has stabilized at its normal operating temperature. Occasionally, you may see your oil pressure drop to less than 2 bar. This may happen on very hot days when the car has been driven particularly hard. You should be extremely concerned if the oil pressure dropped to less than 1 bar. This is indicative of an problem with the oil pressure indication or the oiling system itself. Under these circumstances, the car should not be driven until the cause of the low oil pressure indication is determined and corrected.

Understood. The oil pressure at cold startup is at 2-3 bars which would not be normal. Could someone give me a list of things to check before I drop the oil pan??

How did you check the oil pressure relief valve? Did you have this issue before the re-seal? I would suspect the OPRV if you had it out to replace the filter stand gasket.
