well today I had the cy2 serviced after 162K. Replaced plugs (first time in 9 yrs ) and air filter with the original bosch which was bought from sookai diesel in chagunas, service the injectors and throttle body. Parts came up to around $400.00 ie plugs and filter , and labor was $ 500.00. The mechanic told me I should replace it at 100K or 5 yrs since it was difficult to remove. Next in the coming month of may is oil and filter change, coolant and tranny fluid change.
