Hello, my name is***** will be helping you out! I have over thirteen year of experience in the automotive industry for numerous different makes & models. I enjoy doing what I do, it is my life.

There are several possibilities for a knocking noise, can be bad lifters, camshaft, low on oil or the sleeve for the head itself. It can also even be bad spark plugs (depending on how it sounds)

We are not local mechanics/techs we just do our very best to answer your questions you have. Oil passages for the right head can also be a possibility, you will need to take it to a expert that can further assist you on the situation to help you understand whats going on. If you want to send a recording I can try to assist you. Sometimes a bad valve can cause this as well. If there is no misfire issues then it is likely not a bad valve or valve spring. Hope this information helps you.
