How does the oil pressure look at 1000 RPM.
By Dave Shoe - 07/30/2003 11:04:41 AM; IP 12.2.11.131
If you are idling at 600 RPM or lower, you can get some low oil readings in an older build. If it pops up to 25-30PSI at 1000 RPM, you are likely in O.K. shape.

Too much pressure can have the effect of excessively draining the pan, and with five quarts many CJs with aftermarket pumps have bit the big one due to oil starvation.

Your low oil pressure situation may not be ideal, and it may indicate severe bearing wear or damage, but if the oil pressure behaves well as you tip above idle, the odds are you can drive for a good bit longer without needing a rebuild. Wisdom suggests you pull the engine apart now if you intend to stress it at all, but chances are you can have fun for a bit before anything goes ballistic.

JMO,
Shoe.
