My 2004 S4 has had an oil leak in the front of the engine for awhile now but has recently gotten worse. I can’t see exactly where it’s coming from but I’ve already replaced the front crank seal and valve cover gaskets. I can see it dripping down onto the coolant crossover pipe and more towards the right side (passenger side) of the engine. My only two guesses are either the oil cooler or where the upper oil pan bolts to the block. But I haven’t found any of those being common leak points on any forum. I have access to a lift and tools but the car is my daily driver. Any tips or links to other posts would be greatly appreciated. Thanks!
