Hi everyone, I am new in the forum I’m looking for a used or rebuilt engine for my 2004 Ford F-150 and need some advice on where to start. My truck has a 5.4L Triton V8 and the current engine is no longer running due to severe knocking" or a blown head gasket Should I be checking local salvage yards or online marketplaces I have also seen on the online website https://usedpartsjunction.com/produc...rd-f150-engine. Can anyone help me Select the correct engine? I have asked this before also, I did not get any solution, please give me a good advice.
