I'm a new Jeep owner, and this is my first post on Jeep Forum, so bear with me...
I bought a 2000 Cherokee Sport in June this year. My wife and I love it, but I'm puzzled. The long story short... It was leaking oil just a little when I bought it. Just a few spots showing up in the driveway. Took it over to the local shop and had the valve cover gasket replaced. The rear main seal needs replacement too, but we couldn't afford it at the time with new tires and brakes on the bill. The service tech put what he called a diaper on to help with the leak.
There's the backstory. Now the issue is this... The oil dipstick always looked low to me, even after I changed the oil and put in 6 quarts, it never registered right at the OK mark, always an inch or so lower. This week though, the dipstick was bone dry. Thinking the rear main had taken a turn for the worst and we were hemorrhaging oil, I put in 3 quarts to see where that got me, but still, The dipstick was dry. I put in another 3 quarts. The dipstick registered, but barely.
My wife absolutely had to get to work that day, We only have the one vehicle, and I didn't have time to change the oil before to assure we had the correct level. She drove the 25 miles there and back on faith and without a problem. This morning I was able to do an oil change. What drained out of the pan was... gulp... almost 10 quarts of oil. I put in a fresh 6 and checked the stick, and it barely registers anything.
My questions are these.... How might my dipstick be steering me wrong all of a sudden? And it drives fine now, but I know too much oil is way BAD. Especially that much. Could 10 quarts of oil have done anything terrible- long term that I'm just not feeling yet?
