The rope seals they sell today are real junk. In the old days before environmental issues they made these seals with asbestos fibers which swelled and sealed OK. Today you are better off ussing a replacement rubber seal and use rtv on the seams. The new rope seal will definetely leak and you will be replacing it sooner than later. When you eventually do a engine rebuild it is possible to have end of crank machined to accept a modern Neoprene full circle seal.
