lol, i'm with joe. i too hate oil leaks.
i wish and hope frank is wrong, but i suspect he's right... i've got maybe 1000 miles on my new rear seal and it does seep a tiny bit. i live in fear of it turning into a real leak. the first one failed in 20 minutes. the guy who installed it is an experienced builder. he says, and research backs him up, that most rope seals last the life of the engine, but once in a while one fails early, and once replaced, is fine. i'm hoping of course thats the case here. good luck joe! |

I've never had one fail completely, just tried replacing one in a near (or over?) 100K engine once and it didn't help much, so had to go back and do it again.... which was better. Second time I just replaced the lower and packed the top with a brass punch, cutting small pieces of another seal and packing those in also. Still "marked it's spot" after that, but didn't coat the clutch any more. That was the first one I ever did. Had better luck on a couple rebuilds later, but they always left a little spot. No more than a friend's Harley though...

I would like to point out that I owned a 62 Classic wagon with the 195.6 and 80000 miles that never leaked a drop. This car does not just mark its spot, but leaves a puddle of oil anywhere it has been parked with the engine having been run long enough to warm the oil.

I've had a couple that didn't leak enough to "mark a spot" -- all had never been rebuilt. Don't know how the factory did it, but installing a rope seal is a lost art for sure!! At one point I looked for a neoprene seal that might be adapted. The area of the journal where the seal rides is the same diameter as the bearing journal, IIRC. I never did find another engine with a close enough journal diameter, but only had some Chilton's manuals to search... and I didn't look for long. Even if the block and bearing cap needed some minor machining it would be worth it for rebuilding. I was hoping to find something that would fit the groove with some trimming of the seal and/or shimming in the groove.

Joe, you might want to just pull the bearing cap and pack the old rope seal with a brass punch, fill the resulting hole with new and not even remove the upper seal completely. It's just a packing -- would be the same results as tightening the packing nut on a water valve.
