Before you use those products, try one quart of Marvel Mystery Oil in the crankcase with an oil change. Run the car for 300 miles, change oil & filter and repeat the MMO treatment. If you notice any change, even if the leak becomes worse, repeat the same dosage with another oil change after 1,500 miles. If the leak improves gradually, perform a third oil change & MMO treatment for an additional 1,500 miles. There is a good chance the leak will disappear after totaling 3,300 miles.
I fixed several leaks throughout my engine in this manner, including the rear main. The reason turned out to be micro-sediments in the engine had broken free and become lodged in the seals. The MMO gradually dissolves the sediments and thereby restores proper seal function. In the process of doing so, the MMO forces some sediments past the seal, which is why the leak may get temporarily worse. Do not become alarmed, since the MMO can in no way alter or damage the seals or any engine parts. In fact, you can use one quart MMO indefinitely in the crankcase for the life of the engine for superior wear protection and cleanliness.
I have used the ATP AT-205 Re-Seal with success. The key was to use only 2 oz. instead of the whole bottle. Give it time to work, approximately one month & 1k miles of driving, before adding two more ounces on a fresh oil change.
