    Default Rear Main Seal

    Ive got a '95 silverado with a 5.7l in it and i have a small leak from my rear main seal. Its not big, just a few little drips on the bottom of the oil pan show up every day to two. Should i be worried and is there a way to fix it without pulling the motor or dropping the tranny to get to it? Thanks.

    Are u sure it's your rear main seal? It could be an oil pan gasket leak. And no there is no permant fix to the rear main seal unless you change the seal. You can buy additive fluid for a rear main seal leak but it's only temporary fix if that.

    Yeah man the only way to fix a rear main seal leak is to replace the rear main seal. You can slow it down with some lucas rear main seal repair but it wont last forever. Then again nether will a new seal. I would check to make sure it isnt the oil pan forst. that is so much easier to fix. would hate to see you replace the rear main just to see that it was the oil pan all along.

    And a few drops every few days isnt gonna hurt it just keep an eye on it if it proves to be the rear main and not the Oil pan.. These monsters are known for the rear main leaking..
