My mom had a Comanche 4.0 in it and over filled with oil
She contaminated the vacuum systems and she thought the engine was blow up, She lived in Ill. at the time and I lived here in Arkansas so I took a trip to here house a 10 hour drive and the shop all ready did the over hall and hit here with a $1.600 bill, I looked the engine over and sure as hell they did not even pull the exhaust off I was a young 33 years old and I drove the Jeep back to Mendota a town just 20 miles from my moms house and raised all kinds of hell I told the little town police department my complaint and I was headed there now, I got to there business and ask for the owner of this damned place and that I drove all the way from Arkansas and was a mechanic "A little bull S on my part. I said I will have this place shut down and we could see a police car just parked up the street.
A long story short mom got $1.380 back and they claimed they sent the jeep out to get dun and they would take care of there lose there.
My mom was soooooo happy and learned a good lesson, Always let your engine sit for a good 15 minutes before checking the oil.
