Why does my Toyota RAV4 make a noise when under load?
Recently started hearing a noise from the engine area while under load around 4000rpm. Sounds like a bad bearing sound but I only have a little over 40k kms. I checked the oil thinking it might be cam noise but oil was fine. Anyone else have any issues under the hood of the 4.4 Rav? I have a 2013 Rav4 LTD. Could you post a recording of the noise?
Why is the oil pressure warning light not working?
What may be happening is that the pressure drops low enough to activate the light when the engine is at low RPMs, and the oil pressure rises just enough to extinguish the light when the RPMs increase. I’m not sure if I’d drive it like that. Low oil pressure means that engine parts probably ain’t getting enough oil. Good luck!
