Hi gurus,
My 12yrs old Latio is experiencing a sort of rumbling noise from engine during cold start or at low rpm <1200 (move off from stationery)
The noise disappear at cruising speed
A workshop diagnose as tappet noise and recommend for top overhaul
My car mileage is now 260K km and has never undergo any overhaul before and is left about 3 yrs (renewed coe for 5yrs in 2015)
Is this the only option? will it lead to more problem if left unrepaired?
Some may remember that my engine is also consuming engine oil and i top-up like 1L/2weeks
Also, I just changed a second hand gearbox in Dec 2016......
Any advice for me?
TIA.......
