replacing the timing rails should be about $7k, if You don,nt do it someone else wil. your engine is a n62 not a m62b46 is a 4.6is

Thanks electricalserv. I saw M62 on the two water pipes above the
 

valley pan. I thought the N62 made its debut in 2002. I may be looking at 3300-3700 depending on whether or not the timing has to be adjusted. Sounds like you may be giving me the dealer's estimate for repair.

no biggie..............good luck with your X5.

thanks; hoping all estimates are lower than yours.
