I'm trying to remove the timing chain cover on my 91 420sel.I have remove everything around,and started to remove the cover.It moved for about 1/2 inch,and now it wont budge,especialy on the lower right side.What could be holding it?The cover is wedge between the heads,and the upper oil pan.Does the oil pan need to be lowered to facilitate the task?Was wondering also if the worm gear for the distributer simply slides out of the cover?
Thanks for the help.
