How to test the oil pressure on a Chrysler Sebring?

The pickup tube has a screen on it which is fine enough to catch a mass of junk. This then leaves little room for oil, and at low rpm the pump cannot draw enough to make proper pressure. To test this run the engine until the oil light comes on at idle. Then shut it off, wait 5 minutes and run it again.

Why does my Chrysler Sebring smell like oil?

What’s happening is when you come to a stop, your engine’s rpms drop to a level that lets the oil pressure drop too low. That’s from the oil being too thin for the clearances in your engine after they have been worn out from all the miles. If you can smell oil burning, it may be working it’s way past the piston rings or valve seals.

What to do if your Sebring oil is leaking?

As dbll responded, first check oil level. If it’s low it is leaking or burning. Verify the correct viscosity oil was used. A clogged screen in crankcase, or oil filter, or failing oil pump can be a culprit. A pressure check may identify internal wear or faulty sending unit.
