I own 1998 xk8 4.0 purchased with 36006 miles it now has 42000 miles
with no issues.
How concerned should I be at this point in time about the timing chain tensioners and when should they be replaced ?

Thanks

 

Welcome Rob2014
I did mine at 50,000 miles and the passenger side secondary tensioner crumbled in my hand when I removed it. I'd be pretty concerned

enjoy!!

 

Just do them...at least the secondary tensioners...those are the ones that severely damage the engine. On a car that age the plastic tensioners can go at any time.

 

Absolutely +1. You're playing with fire.
