This is on my CIH 1660 combine with the IH diesel engine. Just had the engine rebuilt this past summer after an oil issue.
First time actually working the engine today...I shelled some corn. At cold startup the oil gauge goes to the halfway mark at idle. I noticed today after about an hour of use that if I take it back down to idle the gauge dropped way over to the left in the red area. Oil warning light works and it did not come on. Shut down right away, let it cool down a bit and checked the oil, engine still warm. Looked a bit low but I cannot swear by it because the oil is really clean. There is oil on the dipstick but hard to tell how high on the dipstick. I added two quarts, one at a time, checking pressure and this did bring the pressure up above the red (at idle). Pressure on gauge at full throttle is just above the halfway mark cold and just below it hot. Remember, the oil warning light never comes on. I see no smoke, no sign of leakage. I have a few ideas of my own, just wondering if the more mechanical types here might have some ideas as to whether I have a problem and where it might be?
