sounds like timing chain is rattling

[Frankenstien93]

at about 2700 to 3000 rpm my timing chain makes a rattling noise. ive been told that nissan acually had a problem like this and deleated one of the guides so i was wondering if there is any truth to that and how i would fix this problem? any information would be helpfull. (1993 240sx,KA24De)

You can pull the valve cover and remove the top guide, should be two bolts, and the rattling will possibly be gone. It's true, many members (if not all) with a KA24DE have done it.

Commone occurence on the SR's too. Should solve your problem, if not you didn't have anything to loose. If that doesn't work, timing chain tensioner would be next think to change.
