I just picked up a 1998 xk8 coupe with 110,000 miles. It seems to run great (just a few goofy issues) I don't have access to much maintenance history, but i was wondering the chances the engine could still have the plastic timing chain parts. Also, any idea what a shop should charge to pull the cover to check?
It sure is a fun car to drive, any input appreciated.

I would absolutely check the tensioners, immediately. When I bought my 2002 XKR almost three years ago, a file the size of a phone book with every service ever done on the car came with it, all done at the local Jaguar dealer (San Jose, CA). Since I bought the car with 60K miles on it, I mistakenly assumed that with so many trips to the Jag dealer, and with the tensioner issue well known for years, that it had been done. Last month, with about 109,000 miles on my car, I went to start it and heard a horrendous sound as soon as I turned the ignition. Fortunately (really miraculously), the engine was spared any damage by my quick reaction and sure enough the upper tensioners and timing chain on the driver's side were both broken. Instead of a $6-7000 engine replacement job, it was a $1500 job including the upper and lower tensioners, chains, valve gaskets...on both sides. Been running fine ever since. Check the tensioners and save yourself a lot of money and headaches.

If the PO had the tensioners replaced, you could be almost certain it would have featured as a selling point due to the cost of the upgrade.
As other have said, don't guess. Get it checked.

Got my XK8 Back from the shop today...
After 110,000 miles it did indeed have the old plastic tensioners and guides.
The Mechanic showed me the old parts and all the tensioners and guides were cracked and living on borrowed time. So new timing chains, tensioners, and guides were installed along with a new water pump and serpentine belt. I had a couple of other small things done, and $1800 later I'm very happy to drive my jag with no worries about the engine.
Again, thanks for all the great advice.

I`m happy to report that I have my car back from cam tensioner replacement and all is good. the tensioners were still ok, but had small cracks started. I had the tensioners replaced, new water pump with steel impeller and steel thermostat housing. I also learned that there is a heater hose that runs under the intake manifold that was getting soft so it was replaced too. All told, $1250 and happy to pay it.
I had done lots of research about the xk8 engine and did not know about that heater hose location. Coventry motors in Phoenix did the work and when I picked up the car they had it washed. Vvery pleased. Tim, the wrench, says that once the ABS module is repaired and the trans serviced that these cars are pretty bulletproof.
