Is a Rear Main Seal really needing to be replaced?

    Is a Rear Main Seal really needing to be replaced?
    My 2004 4Runner V8 with 205,000 miles is in the shop. They say it needs the Rear Main Seal replaced ($1750) and the Oil Pan Gasket needs a Reseal ($705).

    This 4Runner leaks Zero oil on the driveway.
    It may have some oil on the bottom of the oil pan or engine but there is zero oil on my driveway.

    If it's a minor leak and not serious I don't want to get these replaced.

    What do you think?

    If there are no drippings of liquid, just dirty sweating, do not change it. Anyway for that mileage, shaft at seal area already grooved, and new seal will leak even more, forcing further repairs. Oil pan gasket is diy.

    Update - I got her back from the shop
    Shop said the Rear Mail Seal was leaking and the Oil Pan Gasket needs a Reseal.

    I didn't get either service.

    I got her home, crawled underneath, ran a paper towel all under the oil pan and the bottom of the engine/trans where they meet and it only pulled up older, drier, caked-on black grime. Zero wet, fluid-fresh oil on the paper towel.

    It makes me think there is not much if any leak.

    What do you think?

    Always been told that unless it leaves a spot on the concrete, don't mess with it.
