Me Too

Model Years Affected: 1994, 1995, 1996, 1997

Engine Affected: 3.2L V6

Average Mileage: 181,750 mi (115,000 mi - 230,000 mi)


Varnish build up in the engine can cause one or more hydraulic lash adjusters to stick and cause a ticking noise in the engine. The noisy hydraulic lifter will need to be located and cleaned to stop the noise.

    I got a 1997 Honda Passport with 3.2 engine with 180K miles and it had a ticking noise in engine.
    I put some engine oil additive in it, and it did not seem to make any difference.
    I sold this same Honda Passport with 192K miles and it had a ticking noise in engine. It was running strong when I sold it, just got tired of shifting that 5 speed.
    I still see it being driven around town a 2 years later, and I bet it has over 200k now, and bet it still has that ticking problem.

    Started to notice the dreaded ticking, going to try the engine flush when I get back from theis roadtrip. Yikes. Hope I make it back to the garage.

    added heavy weight oil at oil change, no real improvement in tapping noise, but engine runs strong and smooth
