    Hello all 4th gen Civic owners! I just picked up a 91 Civic Wagon from my father in law that had been sitting in a garage for years. It has no rust,2wd with a manual trans. The best thing is it has 76k original miles. It has been maintained with the basic oil, timing belt , brake replacement. Are there any issues I should be aware of?

    Thank you, I hope to drive it as much as possible before it gives out. What is the average life span on this engine if properly maintained?

    Convert to full synthetic motor oil if you want to prolong the engine's lifespan.

    And fix any engine oil leaks.

    About 80K. When it goes, just purchase a rebuilt one with a lifetime warranty.

    A little Seafoam added to the gas tank should be fine.

    Then Ohm test the switch itself with the transmission in neutral. Is there continuity between the two terminals of the switch? If so, replace the switch.

    Thanks- I do wonder if these cars would qualify as -Classic car status? Also Autoblog has a cool write up on a 89 Wagon they found in the junkyard. They mention 80's engines had HG issues?

    The y-tube info vague on how to replace the B/U switch? It appears to on top of the trans below the distributor? I guess it screws out and there are 2 wires to disconnect? The replacement part looks like it has 2 plugs to insert wires in and the other end has a button type switch on it. Has any body replied their's?

    Thanks - I just read where the exact location was and unplugged it from the main harness for now. To answer your question I have not checked it yet. FYI- T he lights are off ! but obviously it won't work if backing up. Good for now. Thanks again for responding. The car is running great overall. I have put more miles on it in 2 weeks than it had in 2 years!

    Generally, 25yrs old is the "Classic" status.
    I don't recall those motors having any sort or head gasket issues, those 88-91 d series motors were rock solid reliable.
