Ive got a 97 altima and cannot get the timing cover off ive took off the oil pan oil sump but cant get the other pan off for some reason the timing chain cover will move freely but seems the only thing holding it is the pan thes attached to the block itself any hints on how to get this pan off i had to do a complete head job with cams and all because of the faulty upper tensioner breaking...that little thing broke both cams bent all the valves in my head and left me with the biggest headache in the world
