I have a 2003 escape and it started knocking and at low RPM the oil pressure light comes on. I know it is a serious engine problem, has anyone experianced this before and exactly what was the damage? I did a compression test and #2 cylinder was lower than the rest, i put some oil in the cylinder and it brought the compression back up. I talked to my buddy who is a mechanic and he thinks it is aconnecting rod bearing. any other ideas? I am just trying to decide if it is worth fixing or if I will sell it for parts as is.
