Timing Chain Removal

does any one know, if the entire head has to come off the motor in order to remove/replace timing Chain on a 2006 650I. My chain has apparently stretched, but looks as if I'm going to have to remove the head to get past these guid rails/bars.

Thanx,
Dawg

It takes a special tool to install the timing chain. The front covers will have to be removed. Contact Keif on the 7 series forum, to see if he can help you. I think I remember him doing this job, & he might have the tool. It might possibly be a bad guide, or tension adjuster. This should help.

I just finished up a total rebuild on my 645. The heads will need to come off in order to properly remove the lower timing cover. Also, replacing the timing chains will require the removal of the oil pan. Make sure that you check your valve to piston clearances, it's very uncommon for the timing chain to stretch without major component failure.
