Rear Main Seal Sweating

Post by eebh2 »

So took the Hummer H2 in for a oil change and am told the rear seal is sweating. No oil on the ground as in no oil leaking that I can see. Should I be concerned or is this a common problem. I will mention it to my mechanic next time I'm there but thought I would get thoughts from members on here as well. The guy wanted to add Lucas stop leak to condition the seals but I said I will pass for tonight. Thoughts??

I use Lucas but i probably use it incorrectly LOL I put a bottle in about 100 miles prior to an oil change and then flush it out with the old oil.
