Problems with XF crossflow
My Question is this my son and is friend have come to visit me which was a 3 hour drive. Now when he starts up his falcon it ratles someting shocking. It sounds like it might be tappet rattle. So he pulled the tappet cover off. We started it up to find out were the rattle was, but I noticed there was no oil geting pump into the rockers. Is that fairly normal at a idle or not??
About three seemed to be pumping up oil, but the rest are dry why is this so??
