Oil leak from rear main seal

Discussion in 'General Motoring' started by Dan Staringer, Aug 8, 2004.

  1. Hello,
    I've had a small oil leak from apparently the rear main seal on my '93
    Honda Accord. My mechanic just identified it today when doing some other
    unrealated repairs. I knew that I had an oil leak from somewhere that has
    been a slight nuisance but not terribly cumbersome. Very little oil hits the
    driveway. It will cost about $300 to get this repaired. The car has around
    180,000 miles on it and I would like to drive it for at least 250,000 if not
    more. The balance of the engine and car is in excellent shape.
    Is it worth putting the money out right now to replace the seal or
    should I wait until I need some other repair that can be done in tandem so I
    don't have to have my mechanic pull the transmission just to get to this one
    problem. Thanks in advance for replies.

    First make sure that the leak really is coming from the rear main seal and
    not from somewhere else, e.g., valve cover gasket, distributor o-ring, etc.
    and leaking down to the bottom of the engine. You did not mention if your
    tranny was an automatic or a manual. If the latter, then maybe the rear
    main seal can wait until you need to do your next clutch.

    You can try a dose of AutoRX. Its been known to stop oil leaks. If its
    oil gumming up around the seal it may fix it.


    You can get test information and opinions on it from:

    Clean it up real good, and be SURE it's the rear main seal. My bet is
    that the oil pan gasket needs replaced. That's what it was on my '92
    Accord 5 speed. bob
