I keep hearing about Corolla's and sludge Problems. Do these sludge problems affect the 9th gen? Thanks

^X2, I have not heard much about sludge in corollas, but the Camry engine from 97-01 had sludge problems, due to faulty a faulty PVC valve and other problems. The early 1zz fe had problems with oil consumption, but not sludge.
