: low oil pressure problem

08-29-06, 10:02 AM
I know this topic has been discussed to death, but i would still like some input from those that have found solutions.

Catera engines (mine is a 98 with 150K on it) seem to lose oil pressure at low idles and high temperatures. Everything from changing the oil to changing the engine has been tried and suggested. I've tried different oil viscosities , with no luck, and my next step is changing the oil sensor. If that doesn't work , i might try flushing out the oil cooler ( in and out) and then replacing the oil pump.

What I would like to know is where to get an oil sensor unit, reasonably priced as well as an oil pump). Also does anybody have the parts numbers?

To those that have added after market oil coolers, did you eliminate the factory one or added a second one?. Do you have a link as to were to purchase them?

I haven't had much luck finding these parts either in Canada or on- line, so any help would be greatly appreciated.

Great site , thanks for all your assistance.

My 98 Cat experience the same problem two years ago, I had to replace the oil pump. It's an expensive repair.
