I was told at the dealership that there is no way to clean them or service them.

BY THE WAY everyone, if the dealership says the failure was due to "bad gas" and not the carbon build up we know it to be then it falls under "failure to properly maintain vehicle" and they won't honor the warranty.

 

I would disagree with the dealership as I have had injectors cleaned, blueprinted and had new o-rings installed before. And it is super cheap. Maybe there is something specific to these injectors but more likely they want the $$ out of the replacements.

 

There are two businesses near Seattle that clean fuel injectors. One of them has a mail in service. They are called Witchhunter Performance.

Before spending $4,000 on 8 injectors, it would make sense to give them a call to check up on whether the dealer is correct on the non-serviceability of the old injectors. It may be that given the extreme fuel pressure of the DI engine that they can't be cleaned, but I would not trust that to be the case.

Even If the injectors are already replaced, it might help recoup some expense to have the old ones serviced then sell them as reconditioned for perhaps $2,000. They may also be worth a couple of hundred as-is.

FWIW the Mercedes I traded in on my F-Type was costing an average of $7,500 per year to service for the last several years. Expensive cars are expensive throughout their life.

 

I am glad you mentioned that name because WitchHunter was who I used back in the day for my injectors (and I couldn't remember their name). Definitely worth giving them a call. If they can do it and you can do without this car for a little while, having an indy shop remove the injectors and getting them cleaned would be a much cheaper alternative.

 

They are the ones to use for sure.

 

I have used CrusinPerformance for injector service in the past on my boosted Mitsubishi Galant VR4 and just got off the phone with the owner, Rich.

He said they can be flow tested, inspected, and cleaned just like any other injector with one exception.

He cannot flow test them at operating pressure levels, only at 5bar. But that will give you a great indication of how they are performing before and after cleaning.

The only thing he does not know is if he has the o-rings to replace the old rings.

We would need to get him an injector so he can see if he has the seals in stock or if you would have to get them from Jag before they were reassembled into the engine.

Cost is something like $25-40 each to inspect, test, clean, and retest.

Does anybody have a GDI injector for the 5.0 laying around? I would love to have him look at one and see if he will give us a "forum discount" for service work.

 

Wait.. are you guys serious? SO instead of brand new ones the old ones can be fixed?

 

Injectors are very durable. You will rarely ever see all the injectors fail at once, most of the time the issues you have can all be traced back to a dirty unit.

If you experience a total failure, odds are it is a ECU, pump, or wiring issue and the issue of the injectors not working have nothing to do with the injector itself.

Once cleaned, tested and seals replaced (very cheap) they are good to go.

I am not saying they never fail. Just not all at once.

And if you ever have to have a unit replaced, keep the old unit and have it tested, you may be able to have it cleaned and recoup some of your money by selling a reconditioned unit.

 

I might have my injectors pulled and sent out for cleaning instead of paying 280 each for all 8.

 

If you want to chat with me so I can tell you what I was told, send me a message with your phone number and a good time to call.

 

Awesome forum support here!

First before anything else I would take it to another reputable independent shop to get a second opinion. As was said it could be something else totally unrelated.

 

The Op never mentioned what was wrong, just provided a list of parts replaced while shotgunning an unknown problem. A dealer interested in boosting his bottom line would not choose injector cleaning as there's not as much profit. There's also no evidence that the injectors were dirty any more than they needed changing.

 

Sorry guys, I sort of hijacked this thread.
The original poster had issues similar to what I am going through right now.
So he already had everything replaced under warranty, I am still in the area of one thousand miles (400 here) before the warranty kicked in so now I am having to scramble to get this fixed.
I am so not paying the dealership 8500 to pull and replace my injectors when they seem to be just shotgunning the solutions.

 

If you do clean the injectors you might want to clean the tank and inspect or replace fuel lines between the filters and injectors. If the fuel lines are disintegrating (e.g. from ethanol) they may clog again. At a minimum flush all the fuel lines and examine what comes out of them.

 

Neither of you have mentioned what problems you're experiencing, just a burning desire to blame the injectors.

The discussion of Satan ethanol is just too tiring a subject to rehash.

 

I agree. I have had routine things done on my jag, and even made some mods. And, she runs like a champ, I average about 90-110 on the highway smoothly (installed a race super cooler, K&N Air Filter, now building a new race grade Cold Air Intake system).The warranty ended, and I thought of getting a new car...but not a huge fan of plastic and vinyl and didn't want to downgrade to a V6...I rolled the dice and won. Not only has she ran like a champ after the warranty, but I find that taking your jag to a respectable mechanic (performance knowledge/Good Price) and paying out of pocket is in the long-term the cheaper route. A lot of people complain about Jaguars, but they are like any other car...they need love and attention and imo blows any of its direct competition out of the water with Style, Performance, and Driving Experience. Sorry for your bad experience.

Sidenote:Austin is a much better place to live. Lived there for 5 years and loved it. The roads in the Capitol are well maintained and Austin is a cleaner city overall.

 

What kind of Jag? If it is an XF we are severely limited on intake and aftermarket inter cooler options.

 

Mina Gallery has some excellent performance upgrade options for both the XF and XFR at an affordable price.

 

I have looked around. Of course, you could always use a Mina intake specifically fit for your jag. And, then contact QuickSilver for the Exhaust.
