I just replaced my rear main seal. It wasn’t leaking, but I figured since the engine was out of the truck, might as well replace it.

The install was simple enough, but once I finished up and inspected the new seal, I noticed there was a small gap in between the crank and seal on the right side. Isn’t it supposed to be tight against the crank all the way around? Did I get a defective seal??

Ive seen them have a gap like that a lot when you pull out the plastic sleeve and it stretches them, usually they go back down. Never had one leak that looked like that.

Once the engine temp gets up, it should tighten up. I’ve had front and rear seals do this occasionally.

I had my trans out and didnt replace the rear main seal because it didnt leak. I must have rattled it around too much because it started leaking immediately after.

Yea, I bet it will go back. Also, that's more like the dust cover. The teflon seal is on the other side and you can't see it when installed.
