NO; it should be properly fixed; if not it will ruin your rear brake as well. ---

For one in good shape the only cure is to replace the seal. For an old beater you can try one of the additives from the parts store. ---

Doc, unless you know something I don’t I assume he’s talking about the rear main seal on the crank. ---

If the leak’s that big, I would think the engine failure would be a bigger concern. ---

Sorry, I took it to be rear axle seals, which often leak where I live due the severe temperature in winter. Rear main bearing needs fixing if the leak is significant. ---

well, the rear of what ? If only the op would give something accurate to work off of. ☹ Waaaay too often a customer’s description needs more info. My cutomer’s “front seal” turned out to be the rear axle pinion seal ! ---

Ken’s right, knowing what oil is leaking would be a huge help. OP? ---

I had such a rear bearing seal leak (significant)on a Nissan with an otherwise perfect engine. My mechnic did the work for about $850; the seal is cheap but the labor is a killer. No more drips on the garage floor.
