First: my XKR has 86,000 miles. Also, the car drives perfectly. No issues.

So I'm heading across country again in a few weeks.
And my Miracle Warranty is coming to an end, and will have expired by the time I return.
And I've got a credit (long story) at my pricey yet beloved Jag dealership. (For anyone in Southern Cal, I cannot recommend Rusnak Pasadena highly enough, in terms of the knowledge of the techs, the quality of the work done, and the overall professionalism of the experience. Price, however....)
So I'm thinking I've got one visit to Rusnak left, then I go on the hunt for a less-expensive indie shop. I will make that final visit before I head east, and they will give my car a thorough once-over, and if they find anything go to my warranty one last time. And I've got that credit to spend.
Here are four services (that I would have to pay for out-of-pocket) I think should be done, but I can't afford them all at Rusnak. Which would you do? Or are there any others I'm missing? Obviously I'm thinking specialized work.

Change out the spark plugs.
- I've read threads on this, and it sounds like a couple of the plugs are dicey to get to on the supercharged engines. Given that it's probably a once-in-the-life-of-the-car job, I'd prefer someone else do it.

Timing chain.
- again, not an issue, but....

Transmission fluid change
- they have already said they're not a fan of doing this, but will do it.

BG "upstream" full system fuel/air system cleaning
- lots of threads about this. They have already done this (at 40K miles) and recommended it be done again. Since these are DI engines, the idea is they bring in the cleaner upstream of the intake valves, so it cleans those. I put in a can of BG44K every 10K miles but that's downstream of the valves.

Thoughts? Thanks as always....

 

I would do the spark plugs and possibly the BG. Walnut blasting is best for cleaning off DI carbon build-up but is labor pricey, but works really well. Timing chain i wouldnt even touch unless absolutely necessary. Same thing with trans fluid replacement. IF you dont fell any issues with shifting, i personally wouldnt do it.

 

If you haven't had the transmission fluid, S/C fluid, PS fluid, or rear diff fluid changed - you're overdue.

Belts (2) and plugs are a 100,000 mile maintenance item, so I wouldn't bother.

Timing chain - no.

New air filters and fuel filter can go a long way.

And of course make sure they are using the correct spec fluids.

 

I'm a new owner of a 2010 XK with 50K miles. I wanted to start my ownership knowing exactly what had been done and when, so I had the Jag dealership do the full fluid change, except the transmission, and a good once over of everything else.
The transmission will get done sometime in the next 6 weeks after I get it out of storage, my local BMW Dealership quoted me $800.
I try to do preventive maintenance as often as I can.
At 80K I'd go with the transmission.

 

Read this post, then follow the instructions. Wave hello as you pass through the Pittsburgh area on your way east!

 

PK4144 has a 2010, so no fuel filter. I agree with your summation though.

 

Really? Is it built into the pump/tank?

 

It's actually just a screen around the pickup inside the tank. Not much of anything for filtering, but that's what it's got.

 

Thanks, all!
Seems like everyone's down on the timing chain so I'll leave it. Car seems to be running fine, and I don't know that plugs need attention, so that can wait as well.
Air filters have recently been changed, and I knew that about the lack of fuel filter. (Odd,but it seems to work.)
I've had both the rear diff and the supercharger replaced so I know those fluids are a few years old.
Not really worried about the power steering fluid, so that leaves us with the transmission....

 

Check around at Indy Trans shops. Many cars use the same transmission as ours, unless you're uncomfortable using non dealerships.

 

How did you change oil in the SC. Thanks Dennis

 

Take a look at the DIY sticky on the main page. This DIY post is specific to the SC on the 5.0

I humbly disagree. The power steering hydraulic fluid is paramount to good steering. And a failed or worn rack won’t help... easily avoided by changing the fluid and reservoir. You will be amazed at the gunk in there. Though I’m not as energetic as @Ranchero50 as he posted his solution for cleaning the reservoir, which in my opinion was perfectly done.

 

A person could slowly and easily renew the power steering fluid (which is probably dirty and nasty) by using a baster and sucking the old stuff out of the reservoir every so often and filling with new fluid. It will eventually get to 75% new fluid quickly and never reach 100%, but some new is better than all old.

 

For sure. I did a full flush and new reservoir @ 60k miles. Now I just replace what's in the the reservoir every 30k miles.

I agree with guy, I would NOT look over this service. It is cheap and simple enough to do by anyone.

 

I'll give the turkey baster power steering fluid slow-change a shot. My thinking is at this point that's a service I'd feel comfortable having an indie do and a (probably) lower cost.
