Knocking motor in 2007 Dodge Ram 1500

Thank you very much. I forget to mention When you drive it hardly has any power and still knocks. Replace oil sensor and I think he is going to try to replace the oil pump. if you have any more recommendations I would love to hear them. Again thank you very much

Ok thank you very much

Agree with "tennisshoes". Engine knocks from deep within usually require engine teardown or replacement. The damage is likely already done. A ticking noise is usually less severe and an oil pump may solve that. The best thing to do is measure the actual oil pressure with a mechanical gauge attached to where the oil pressure sender goes. If oil pressure is good and it still knocks that's bad.
