Q: issues after toyota repaired scon tc engine due to excess oil consumption test failure

The extended warranty (there was no recall) that Toyota has offered on your vehicle, in response to the excessive oil consumption issue, only includes the short block, consequently all cylinder head components are excluded. You should measure your oil consumption. If your vehicle is using more than a quart in roughly 1,500 miles, that’s excessive and the cause should be identified. If the excess oil consumption is past the valve guides then Toyota does not cover that. What they covered was defects related to the pistons which are contained in the short block assembly. If, however, oil is still leaking past the pistons, your vehicle is still covered under the Toyota extended warranty. If you desire, a certified mechanic from YourMechanic can evaluate the issue and suggest a least cost repair strategy. Simply request an internal oil leak diagnostic. If you have further questions or concerns as you decide what to do, do not hesitate to re-contact YourMechanic because we want you to make the most of your repair dollars and help you get the best possible results.
