Hoping to get some help in this great forum. Spent all day yesterday replacing the valve cover gaskets to try to stop an oil leak on my 2007 3.5L ivetc EXL with 110K. After several hours and a few trips to the store finally got it completed and definitely fixed one oil leak on the back valve cover. However, when I started the car to check it for leaks on my work I still have one leak which is not coming from the front valve cover but seems to be coming from the studs that attach the O2 sensor housing to the engine. If I start the car and watch it I can see it slowly seep onto the threads. I haven’t been able to find anything online about this although I have seen other people complain about the same issue but couldn’t find an answer. I hope this isn’t a major problem, any help would be appreciated as to what to do to fix this. I’ve attached a pics.
