I have a 94 nsx automatic - at idle i have almost no oil pressure indicated on the guage. At 2000 rpm i have 2 kg/cm2 indicated. So far - no red warning light has appeared! Should i be concerned or is this normal? Thanx for your advice.
This is a common complaint/concern, you can try a new sending unit which may help but it is a $235 part. There is seperate O-SHIT light with its own pressure switch so you are most likely just fine.
Mine does the same thing and I was scared about it at first, after asking a really good NSX guy in the business he told me not to worry and that the psi is really not as low as the gauge makes it out to be.
To save yourself a 20K engine, I would purchae $100 part oil pressure tester to check whether the gauage is right. Follow the service manual procedures and guidelines.
