thanks all for replying. I have sent a few emails to knightmaster in New York and a video, hoping he can help, unsure what will come of that. If anyone knows of an indy or person within 2/300 miles of Virginia who can do timing chains and guides and valve stem seals on a 2007 X5 4.8i, 144K miles, I am sure in the need. I have heard and seen some posts that only M62 engines have this problem, but also seen posts of some of the N62TUs do have timing chains and guides issues. I know mine does for sure. You can hear it clearly when you open the oil fill cap on passenger valve cover. I just can not find a person or indy shop who wants to do the work. Hoping some one at this forum can assist. Desperately trying to figure out a solution to my e70 4.8 typical engine problems dilemma. thanks
