2001 FORD FOCUS LOAD TICKING NOISE

it very well can be that depending on the severity of the ticking noise, if it sounds like its coming from the top of the engine, place your hand on it only when you first start it up and if you can feel it knocking slightly and if the noise dies away once warmed up id say its your lifter, if its a heavier knocking rather than a ticking and comes from below or bottom end of engine it may be big end bearing, not good. try putting some engine treatment through the engine oil and make sure you run it in as directions state then change the oil and filter and see if that helps :)
