Question about 2001 Toyota Corolla
I have a 2001 Toyota Corolla with approximately 130K miles. For some reason the car has started to burn oil rapidly (about 3 quarts a month). The mechanic says that the problem is due to high mileage and I should have the entire engine replaced, which I find hard to believe as I have friends that have Toyotas with 259K plus miles on them and they did not require a new engine. Is this a common problem? Any suggestions? I have regular maintenance performed on the car and any repairs as they come up.
Take your vehicle back to your mechanic, and have him perform a DRY, then a WET compression test. Please provide both readings back to me. In the meantime, ask him what it would cost you to him replace the piston rings. This is your problem. The 2 tests will simply verify me thinking.

This problem is due to Rings of Piston & maybe bore of piston cylinder also lose. So you should change only piston rings. & this cost is not much. If machanic is good.

This is definitely a ring job. The oil control ring is stuck in the piston land due to burnt oil lodging it into place. Do a ring job and while in there drill a couple of extra oil holes in the land for the oil control ring. Otherwise, these littles engines do go 300-400+ thousand miles.

hi, the main cause of major oil consumption is due to cylinder wall deterioration. this is caused be bad piston ring sets that tend to chip of tiny pieces of the cylinder walls over a long period of time. this will start to show in engines with high millage. this will also lead to compression loss as well if it is not fixed soon.
To fix this issue within the cylinder walls, they will have to be machined and a new set of piston rings will have to be fitted around each affected piston. this will stop the oil from leaking into the combustion chamber and it will restore the compression rate as well.
