Recently purchased 2002 Wrangler X. 168k Completely stock as far as I can tell. Day 2 of owning it, after about 180 miles of driving it, the oil pressure dropped to zero with the associated check gauges light while idling at a stop light. Revved engine and pressure climbed back to normal.
Got it home and changed the oil sending unit. Oil change. New filter. For the first test drive it seemed ok. But by time I got it back in the driveway while sitting at idle it slowly loses pressure. Now not all the way to zero. But down around 20psi. While idling it is a very slow decline and takes a bit to get there. Giving some rpms brings the pressure back to around 50psi. No pressure issues while driving.
What are the chances I bought an engine problem? Is it safe to drive while I figure it out?
