most of the fear is in the un-knowing. It's a bit scary diving into a motor the first time fairly deep, but i've done timing chains on a couple M62 now and swapped a couple heads at the same time, did most of the job solo with step-by-step online. Take your time and when something goes wrong as inevitably happens, stop and take a step back, make a post with photos and somebody will be around to give a hand.
