Front crank seal- Is this going to leak?

[Brown747]

Just installed a new front crank seal while I've got the engine out for broken head stud.
Pushed it in with a PVC cap fitting and didn't see that the rubber outer part of the seal got hung up on the edge of the case indent. Not pretty..is this going to leak??

[Ken911]

yes it will probably leak. they dont cost much. But pulling the engine and taking it apart to replace the seal will be a huge pain.

Was the old seal leaking or was it leaking around the bearing O-ring? That seal looks to be all the way in and square.

[Ken911]

yes in and square but the outer rim is torn

That will probably leak, the seal is all deformed now, and is probably not putting even pressure on the seal lip itself. For the 10 bucks the seal costs, and an extra day wait, I would not take a chance.

This.

Ordered...Thanks for all comments.

BTW, I suggest installing the seal dry, or with a minimal coat of oil on it (It looks liek you've got some goop on there?) . Many of the non-hardening sealants can allow the seal to push back out later on as it acts like a permanent lube.

A few years ago we (Souk and I?) were finishing up an engine, installed both seals with something like Curil-T and were sitting back and having a beer admiring the handywork. 15 minutes later both seals went "POP" and came right out.

Yep, now I only use enough lube, sometimes just a thin swipe of assembly lube, to ensure the rubber doesn't get hung up and that's it. You want the rubber where it doesn't contact a rotating part to form a good seal with the metal. Excess lube will just delay or prevent it, IHMO. I'm not a fan of Curil-T and I use the official seal tool...I cheat

Time to build another engine in the spring, Chris. (evil grin)

Before installing the new seal, take the sharp edge off of that area with a small file or knife etc.. or it will do it again
