Hi, I have an m50b25 single vanos (e36) and am slowing rebuilding it as I can afford parts. (for my e30)
I need to remove the head, so I put cylinder 1 at TDC. I did this and saw that the journals on the end of the camshafts were not completely square with the block (arrow on exhaust sprocket wasn't perpendicular either)... so I couldn't get the locking tool on properly. So for some reason I decided to take the vanos off to see if it would make a difference - it made it worse.
Can anyone advise me how to remove the head now that the timing is out - and how to time the cams when I come to put the head back on. Thanks!
