Last summer I bought a Celica from Chariot to give to my preachers kid. Six months later, the kid ran it low on oil due to a blown cam seal and it’s 5sfe developed a bad rod knock. The past few weeks he’s been driving his brothers ‘99 Camry, also with a 5sfe. It died on him today (bad battery), and I went to help him out.... Sure enough it also has a ridiculously bad rod knock. Two blown 5sfe’s with bad knocks by the same kid within the same month. Did some online research and apparently rod knock on the 5sfe is extremely common.
