I hate to post this...
I know there's nothing like seeing a "newbie" post a quesiton that has been asked 1000 times but I've looked and cannot find the information.
I have a neighbor with a '99 Exploder with a 4.0 liter single OH cam motor. What I'm trying to find out is information regarding the timing chain noise at idle, how big of a concern is this and whether ot not this is an interence type motor.
Any help or link to help is appreciated.

ps: If I'm in the wrong section, soory 'bout that and please move me where ever I need to be.

Some 4.0s are known to make a 'marbling' or 'rattling' sound. There is some information on the issue in this thread:

Geez, all of these people with timing chain problems. It's caused by plastic tensioners that Ford used up until mid way through 2000. There is a recall out for the timing chains, but I forget the name of the program. Do a search for 4.0 SOHC chain rattle, and you will find tons of info on it.
