ok so Ive been working on this blown head gasket on my 03 3.5l maxima for a few weeks now and luckily I'm not in a time crunch to get it done. I have it all taken apart all the way down to the timing chains. i removed the main timing chains and now on to the secondary ones. but i cant seem to figure out how to get them off.... i have the guide but it doesn't show clearly how to remove them and I'm just getting frustrated. can anyone help!!
