Oil Drain Plug stripped NEED HELP QUICK
This is most definately not good. Started to do an oil change on my 300e today and found that the oil drain plug came out very easily. Didn't think anything of it until I started to put it back in. It threaded in and tightened to around 8ft pounds and then got loose again. Another full turn yielded the same result. My manual says to tighten it to 18ft pounds. I'm pretty sure the oil pan threads are stripped and am not certain if the car should be driven. Filled it with oil and let it idle for 5 minutes, no leak or spray, but when I put my finger on the plug I found new oil on my finger. What do I do? Is it hard to replace an oil pan? Could the pan be tapped and a new plug inserted without taking the pan off? I would greatly appreciate any help you can offer.
