So I noticed some shimmy in my steering wheel and I brought it in to a shop because I couldn't see anything. Well it turns out that I have small flat marks on my front tires (from locking them after my ABS failed). Well I thought that was the bad part... I also have an oil leak.... except its on the rear main seal and the oil pan seal... So i found that they want to charge me 1000 bucks to fix it... I'm a little bitter and I think Ill just do it myself. I do have one question though, It is a VERY small leak and it started after i put in my Synthetic oil. Do you think I might be able to stop the leak by going back to regular oil??? Thanks!
