Hello, have an o2 sebring with the 2.7...the oil light flickers at idle.. so i pulled the sender.. checked the psi and had 25 psi hot.. had 70 psi at 3k rpm.. replaced the switch and the light still flickers.. not all the time tho.. and the hyd tensioner knocks.. we change it and it was a lot quiter.. now its a light tick sound.. anyone else have this problem with thier 02??

 

Minimum specified oil pressure at idle for this engine is 5 psi. At 3000 RPM, the oil pressure should be between 45 and 105 psi.

You might want to pull that sender out again and make sure the passage leading to it is clean. If the engine is sludged up the pressure may be good but if the passages are clogged, you won't be getting oil where you need it.

Are you using the proper weight oil?
