94 bonneville oil pressure. :(
I've got a 94 bonneville se with 119k miles on it. Recently the oil pressure has been lower than normal. It used to increase about 8 psi when I gave it any gas. Now it stays at 32 or so PSi and doesn't make it past 40 on the oil pressure gauge.
Is my engine dead? It seems to have gotten worse in the last few weeks. :(

I forgot what the required minimum oil pressure is for your Series1 is, but 32 psi is well enough for it to run properly.
I bet you will see your oil pressure high on a cold morning, then it drops off as the engine gets warm correct? This is normal. As the oil heats up, it loses its ability to hold pressure. And it will get worse as the oil gets older also.
How long ago was the last oil change?

You might want to change the oil pressure sending switch. It may be on its way out. It is located immediately above the oil filter and is not difficult to change.

sounds like the oil is getting old, you should be changing it a couple times a year at least. bearings dont wear from sitting, sometimes seals do though, is it leaking any?

I'm going to try and change the oil and sending unit this Saturday. I have a feeling my engine has issues. =(
I just need it to last until January when I take delivery of my new 3 series.
