I have a 1970 CJ5 with Dauntless, points, and Rochester 2G carb. I changed my oil and filter roughly about 1000 miles ago (5 quarts oil). I just checked the oil and I’m a quart low. I keep the Jeep in the garage so I know there are no leaks. I’m not seeing or smelling any smoke, etc. Engine runs great, idles great, no misses or stumbling. Any idea what’s happening or what to check? Thanks in advance for your help.
