My 93 Altima has started making a slight noise from the top of the timing chain cover. My research indicates that this could be a broken guide. So far, I have only found the procedure for a complete upgrade of the timing chain(s). - a fair amount of work...
I was wondering if anyone had removed the guide without servicing the timing chain? Is it a shorter procedure?
I think I have both oil leaks - the oil pan, and the o-ring under the timing chain. So, I might just do the whole procedure, but thought I would check first if it is possible to remove a broken guide without doing the whole job.
Thanks, Robert
