Hello. I swapped out my crank some time ago, and by so doing I also changed the crank seals. The other day I was in the middle of of changing roller weights, when I spotted the seal. The seal was given a small amount of rtv, and lubed in the center. I have only driven about 650 miles with this seal installed. There is no leak as of yet, so there may be no need to change it. And I dont know if its been crooked for the whole 650 miles, or if it has moved recently. There is some baad weather coimg in, so now is the time to fix it, if ita neceassary. Its not crooked by much maybe only 1mm or 2mm. And again not leaking. tell me what you think.   |

Hmm, with no leak I wouldn't bother it. It seams to have bedded into place, try to flush it to the case and it could distort the seal and might leak.

Agree. Leave it. Be sure you have good crankcase venting.

next time you install seal use something that fits around it ac close to the outside edge as possible. most likely its a dent in the seal from install. i and co workers have made the mistake in the past when i was at the repair shop for some years. on cars and trucks the seals are bigger and stronger and last longer but always leaked at some point. if it is dented in slightly like it looks to me it means its pushing on the crank slightly yeah rubber is weaker than metal. but almost every seal that rides on a metal surface cuts a channel in it over time axle seals crank seal input seals and drivehaft seals. new seals are almost always installed slightly shallower or deeper than the replaced one to stay away from that wear mark. if installed right on it it will most likely seep until it finally leaks. i can see a pretty wide wear mark on your "new" crank already which means when it does finally leak. your going to go through it getting it to seal at a later date and time. emry cloth can help trying to polish the crank but the cloth will cost more than the seal does and then the sealing surface will be smaller than when the crank was new so seals will leak sooner and faster as time goes on till that 3 dollar seal ends up costing a crank or worse. not saying its going to cause a major failure you could get lucky but more times than not in the line of work i was in putting it off ended up putting on to the bill. good for the boss bad for the customer and bad for the mechanic who had to fix whatever got trashed.
