Hey everyone! New to the site here.. I have a 2002 lexus is300. About a month ago i ran over something on the freeway that left a pretty bad dent on my oil pan. Now everytime i go to take off i here a liquidy sound coming from the oil pan. The car drives fine and i dont have any check engine or oil lights on. But still i wanted to replace the oil pan and the oil collecter so i bought the parts. I was gonna do it myself but i was not able to because some of the bolts are located in a spot where i can not reach with any tool. Is there anyway possible to replace the oil pan without pulling the engine out? Any help will be greatly appreciated. Thanks!
