My '97 Ranger has 31,000 miles on it. It had 10k on it when I bought it in December 2008. Haven’t had any problems with it. This past Sunday I took a friend to the mountains. One of the roads was a steep slow crawl (maybe 35mph), had the A/C on too. When we got to the parking lot for the trail, I parked, turned it off, and smoke was coming out around the wheel wells. It smelled like engine oil. I opened the hood, but didn’t see anything obvious. Gauges were all normal while driving. After the hike, we drove back without any issues. I drove home about an hour on the interstate today with no problems. No smoke or odor when I got here. All gauges showed normal values.
Should I take my truck in and have it checked? Is there something I can check?
Do you experts recommend anything as far as service for a low-miles older vehicle?
All advice appreciated!
