I had my engine rebuilt in April 2009 and recently when I start to drive for several miles, say 30 to 50 highway, my oil gauge shows that it is low on oil and you can hear the lifters. But I will stop and check the oil,which I also do before I leave the house since this has started, and it shows to be full. I have regular oil changes and I am about at my wits end. Can you please advise me on what I need to check or change? Thanks
oil pressure changes while driving on 1996 Isuzu Hombre
I suggest the Oil Pressure Sensor. It could be a faulty sensor
HI i recently purchased a 97 hombre with 2.2 4cyl. and i am having the same issue, pressure is fine until the engine comes up to temp, and then it goes to 0 when at idle, but is fine at speed. Lifters are noisy when engine is at running temp. I parked it today and do not plan to drive it until i am able to fix it. the only issue i have, is that i have no idea where these parts are on/in the engine. Would you be able to tell me where on/in the engine the pressure switch is, and where the oil pressure pump is located as well.

hopefully you have warranty. it sounds like your pump may be failing. get it checked before other damage is done.
