[i]You can remove the oil pressure sending unit and screw in a cheap mechanical oil gauge from Pep Boys (they have the metric adapters for same also). Just to diagnose. A cheapie oil gauge with adapters ~ $20.
Thank you all for your feedback.
how much pressure i am supposed to get when i hook up the mechanical oil gauge? in other words i guess i need to know what is a 3 bar equlas in PSI?
