3S did tappets as well , but issue not resolved . Finally they advised me engine swap or over hauling. The previous owner was a tax officer and he was so miser that he did not bother to change oil on time , like CVT and engine oil , CVT oil change first time by my self at 60000 and Engine oil driven @ 6000km and was darkish black. , he told me he is very busy to do these jobs. he just told me about shell variant that he usually drove 5000 ~ 6000 , but not confident which one. after purchased, I immediately went to change the engine oil ,found the oil quantity was 1ltr less in engine , I called him and asked him why you have not checked the engine oil that is 1ltr less , he said he don't know , he sold car as its........... You people will be surprised that then why I don't checked the car before buying and why not properly inspected before buying ?
