IMO you should have swapped the ecu from the 1ZZ to the Corolla. Match ecu with engine it was used for as well as the key. I’m not sure if both of these vehicles have immobilizes but in the 2000s Toyota started using those and you have to match keys to ecu. Harness should stay with the car but will have to be modified I would imagine.

Ya gotta rinse and repeat

Blue and Red loctite will come off with an impact. Green not so much but I doubt most mechanics even know about green loctite.

I don’t think it’s that deep. 99% of the population is not going to see any difference between 0W-16 and 5W30. Neither will they notice anything changing oil at 3k, 4K, 8k or 10k. Do whatever you want. Nobody cares.

Maybe look closer at it…

No window for you!!

I had them both and I actually prefer OP’s wife

Yea you can’t complain about the Corolla not riding well since it’s an economy car. They don’t sell because they drive well. They sell because they get 35+ mpg and last until your 60. You had one that rode really bad and still bought another one? All your car purchases except the RAV4 is the same damn car lol why would you think they would be any different?

They snuck that in and it’s not good business practice. That being said you did sign the paperwork so you might be in a legal bind.

Never touch a flooded car.
