Report "I have a 2006 ford Freestyle I’m replacing the timing chain. I had a ticking noise from cylinder 1 closed to water pump. I did a compression test and it was dead. I put a camera down the cylinder and can not find any evidence we’re the valve struck the piston but I have put WD 40 in the intake valve and 1 valve leads down. My question is can a valve just be stuck open or is my valve just plain bent"
