For the past five years, we have had an oil leak above the oil pan on the engine block. I not sure if it is worth fixing or keep the oil level up weekly. I use about 1 qt per week or less. The oil stick is clean, very clean and I told that the engine is still good. I also told once you open a engine expect more troubles down the road and don't open it.
Is there caulking or something that I can put around the outside of the engine to stop the leak or put inside the oil to stop it from the inside?
