I have a Toyota camry 2007 model, 4 cylinder automatic which I got as a used car. Its burning oil (i have used it for about 1 year. I changed oil before a trip of about 280km which is about 174miles. On arriving my destination I realised the oil level on the dip stick was somewhere on the low level point.) My mechanic advised I work on the rings as there is no obvious oil leakage. Should I go ahead and replace the rings? Is it advisable to re-ring (replace the rings)?
You're probably not going to get a good result just replacing rings on a 16-year-old engine unless it has really low mileage. (You didn't state mileage on the car.)
You need to check cylinder dimensions with a micrometer and have the engine bored oversize if needed and install oversize pistons and rings. While in there bearings should be checked, you may find the crank needs to be ground as well as bearings replaced. While the head is off that should be checked out and rebuilt as needed. Etc., etc. - once you're inside the engine the job tends to mushroom if you want it done right.
It would probably be better to install a rebuilt engine with a warranty from a company like Jasper if the condition of the rest of the car merits the expense.
The odo meter reading is 253159. I'm actually not so vast with cars.
Back when Toyota replaced rings on these engines under warranty the cars were still pretty new and you could get away without a complete rebuild. The procecure however involved replacing both pistons and rings, so not quite a simple "ring job". Generally takes more than that though when an engine has high mileage due to wear of other components.

how much did he say it would cost?
