Varnish buildup in engine may cause ticking noise on Honda Passport

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 have ticking i have useing marvel mys, oil, it stops and at idle noise comes back.
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.
