no miles on engine told
no year told wow. 2002 to present,
what is yours?
no service told do you put in fresh oil every year or more? y/n
is the oil level good on the dipstick??????
no country told but there are like 5 engines used world wide and no country told you..
some of these engines are chain drive camp DOHC.
and make noise for 3 reasons.
1: bad chain
2: bad chain guides (one is oil pressure actuator class)
3: low oil pressure. (yes pump of oil level good)
all cars made we an check oil pressure using hand gage.
for sure and so can all service techs (mech) ever for 100 years
many car owners have no idea what is under the hood.
