Honda Passport Problem Report
Honda Passport Varnish buildup in engine may cause ticking noise
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. - Visitor
