Anyone know what might be causing my Galaxy to rattle ?, sounds like a tappet but are these not hydraulic ?, or could it be an injestor noise ?. Sometimes it goes but today it sounds terrible even when driving oil changed recently and new filter all Ford stuff, use the car for work so cannot afford for it to die on me + cannot afford to take it to a stealer to pay for them to look @ it :). Any thoughts on what might be going wrong, read somewhere about an engine flush to clean the lifters and make them seal ?.
