Good morning,

No, you must use the seal on the bottom on the timing cover. RTV will not work. It will break down and leak all over.

To install it, loosen up the first 2 bolts on the oil pan on both sides by the timing cover. Use a screw driver to pry down slightly on the pan. that will give you enough room to install the timing cover with the seal installed.
