I have a fox oil tube on the car but I want to go ahead and put the stock tube back on since the headers and everything are off. I remember I think I took the stock tube out before because i had forgot to lock it back on the header bolt years ago and when I realized it, i didnt want to take the header bolt back loose to re attach it. I think that was my reasoning. Anyway, when my mechanic put the fox tube in, he had to make a piece that would secure it without moving as that tube did not have anything on it that you could attach it to the engine to secure it. He secured it via one of the oil pan bolts. If I take bolt out of the oil pan to get the bracket loose, will that create a leak when i put that bolt back in?
