I have a 2016 Honda civic Touring sedan.  49807 miles, automatic . I taken my car to the Honda dealership to have the oil changed and tire rotated sounds harmless. Anyways they told me that my crank seal and my oil gasket was leaking and needed to be fixed. It's under warranty okay not a problem fix it. After four and a half hours later I'm on the road, The Highway that is. I'm sure by now you know where I'm going with this Scotty. I get about 8 to 10 miles down the highway the oil light on my car starts flashing then faster. I had driven about 4 miles give or take before I could pull over safely. Bottom line the car was knocking and there was absolutely no oil indicated on the dipstick it was bone dry. But there was signs there was oil at one time. The hoses in the car were covered with oil and oil sporadically sprayed in the engine bay.  Oil under the car dripping, on my passenger tires. Honda towed my car back to their service department next day found out the tech didn't connect the return line from the turbo to the oil pan. Honda claims when they drained the oil pan that there was supposedly two quarts of oil in the car, and they didn't see any metal shavings in the oil pan. They told me they put oil back in the car started it no engine light didn't hear anything funny so the car is good to go. My first question is after putting new oil in and hooking the turbo return line back up should they have flushed it and then check the oil pan again to see if there was any metal fragments? That and my first initial thought is if they change the oil pan gasket and the crank seal shouldn't thay had pressure tested to make sure that they had a good steel and if they did that they would have found that they didn't hook up the return line from the turbo? So the manager is telling me that I have a 50,000 miles left on my warranty so if something goes wrong I'm covered. My thought is it is not my responsibility nor the warranty company for their mistake and that they should be doing more to ensure there is no damage done. After this incident the value of my car has now dropped. I stated when somebody pulls up the history of my car I will have a difficult time selling my car. He said that the history on carfax and such is vague and there's usually not any information. Ok , so I feel like I'm in a rock and a hard place with this dealership what kind of demand should I put on them? I don't feel that they've done enough to make me feel confident that there's no damage done to my car cuz I'm pretty sure there is with the knocking and who knows what damage has been done not only to the engine but to the turbo. I had a Toyota for 18 years and never had a problem not even a oil leak. My first mistake was I  bought a Honda. HELP Please and thank you for any words of wisdom.
