I’d had this Camry since new. Changed oil every 5,000 miles, instead of the recommended 10,000. I always heard a subtle ‘ticking’ noise from the motor. The dealer told me that’s exactly how all the 4 cylinders sound.
It is still under 25,000 miles. I’ve noticed more as time has gone on that the ticking now sounds like lifter noise. These engines are supposed to be good designs that have stood the test of time and give 250k+ longevity, if maintained and not abused.
With simple things, like oil changes under ToyotaCare, I’ve had oil underfilled or a bit overfilled, so I don’t trust the neanderthals that are vaunted “Toyota mechanics”. I have checked the oil level every time I’ve had an oil change, so I catch it before I leave the dealership, and get the levels corrected.
I’m frankly afraid to bring it to any of the local dealers, as they all have 100’s of complaints about damaging car engines and other components, or lying to customers that they need something replaced that doesn’t need replacement. Though under warranty, I think these type of shenanigans would be less likely to happen. The problem is that you have to get warranty work or evaluation done at a Toyota dealership only. And when they can’t even do an oil change correctly. how can I get a potential problem properly evaluated?
