I have replaced the oil pan and gasket valve covers in 2004 CRV but still have an oil leak. Where else could it be coming from?

There are several more possible oil leak areas.. Locating such a leak will involve professional *hands-on* assistance - likely uv dye will need to be utilized as a leak source detection tool. Vehicle should be hoisted for inspection. Then there is the possibility the engine is consuming oil as well. Good luck!
