Is it a small or big block? Don't think the rope would work well on a slick finish journal. If it has been line bored a lot, that may be your problem. On chevy's they make special main seals for line bored blocks. On mopars I don't know of any. But what I do is take some brass shim stock and silicon and insert a shim on the seal where it slips on the block and cap, this presses the seal a little tighter and will compensate for the material removed during line boring. If the block is line bored, the seal is already tighter on the crank on the block side, because you machine some out of the saddles but you don't machine the seal groove. So seal is same, saddles are lower

not having any luck with rubber and getting sick of being dripped on Go ahead & install it. put some sealer under it & cut the ends 1/4 above flush them tamp em down. You will be fine

The factory made thousands of BB cars with both seals, very few leaked The rope seals are harder to install properly so they don't leak and they need the knurling to help wipe the oil off the seal If your crank is smooth or worn down on the knurling use the newer Viton rubber seals and use a adhesive type silicone sealer to seal the two ends together and to seal up the side seals to the seal holder
