Omega General Help / Re: Loss of oil pressure

« on: 27 July 2007, 02:16:21 »

Thank you for sharing your knowledge and I think you are right about checking the pressure relief valves first since I do not show any signs oil starvation. Where are the relief valves located? I can clean them this weekend.

It sounds as if replacing the oil pump is a major job. If it is the problem I think I'd be better off getting a new motor. The Catera never really became popular here and there aren't many of them around so finding a used motor here is almost impossible. For that matter finding any parts, new or used, for this thing is very difficult.

Thanks again for you help!!!

Where can I locate instructions for changing the oil pump? Do you know of a mail order house that would carry the pump? I bought this car used and do not know what maintenance it had prior to my purchase so I am assuming the pump is the problem.

Omega General Help / Loss of oil pressure

« on: 26 July 2007, 06:00:43 »

After running fine for about 30 minutes the engine's oil pressure, when idling, drops down to near zero and the oil light comes on. This problem started about 3 weeks ago. The crankcase is full with the right viscocity oil. Is there any history of the oil pump failing only when the engine is warm? Is there another pressure valve or something I need to check? If so, where is it located? If the oil pump is bad, is there any guidance on the procedure for changing it?

Thanks in advance for you help!!!
