1990 Nissan Sentra Problem: timing chain noise.

[tattooyourpet2day]

How big or complicated of a job would it be to replace the timing chain and parts for a do-it-yourselfer? I know the parts are reasonable but that it takes quite a bit of time to complete. Is there a pretty good web tutorial,etc. that you're aware of that would make this D.I.Y. project a little less frustrating? Maybe some pictures,drawings or short cuts along the way? (Like not having to completely remove the oil pan, just drop it down some.) I would appreciate any help or comments. Thanks, Tim

You'll have to remove the oil pan completely to get it done. For someone using the manual and without the help of someone knowledgeable, it would be an all day project.
