I know this sounds lame but... I just bought a 2004 4 cylinder camry and I can't find the oil filter. The parts store said there are two types. I looked all over that engine and I can't find it. there are two pans under it and I think the oil pan is the one on the passanger side but there is no other bolt on that side for a cartaridge type filter. Please help if you can, I have changed my own oil for the last 20 years and this is embarassing.
