- 2002 XLS
Hi,
I think many of you will be VERY interested in this!! I have 2002 xls with 4.0v6. I bought it used at 43000 miles and it now has 59000. It's been "pinging" since I bought it and this has been very annoying. I've replaced O2 sensors, MAF sensor, EGR valve, etc. all to no avail. I've cleaned out the engine with stuff like Seafoam. Nothing has really worked. So I took it in for a diagnostic and now I learn that it's not really pinging but timing chain slap that is due to tensioner wear!!!! There is a TSB on the subject. The repair is in the range of $1500 to $2400 depending on whether it's front of both front and rear chains. I will be contacting Ford on this one as I really don't think I should pay for a defective design. I'll see what happens. The sound is very much like aping or knock or valve train sound and it occurs mainly under load in the range of 2500 to 3500 rpm.
