Hello to everyone, I hope that this thread finds you all well! The world has become a crazy place, Mother Nature has been busy with earthquakes, hurricanes, tornadoes, etc... I hope and pray that none of you have been affected by any of the above!
Now on to my question: 2002 X Type, 2.5 l.
I thought I had my vacuum leak looked after but recently my P0171 & P0174 codes have reappeared. After further intensive investigation it is my opinion that the Seal on the intake manifold tuning valve is done in and needs to be replaced. Does anyone happen to know the part # for this Seal and would you recommend replacing both the upper and lower Seals since I'm already in that area?

i found a thread from 2010 explaining the procedure. Any information would be appreciated! Thanks again for your wonderful help as I have always gotten great help in the past from Jaguar Forums.
Stay well and stay safe! Cheers.

 

I would recommend going to the SNG Barratt web site, one of the forum sponsors and downloading their free catalog. The parts are readily available for a reasonable costs. Make ure you are getting the green updated O-Rings for the IMT valves.

Are you talking about the IMT tuning valves or are you taking about the intake manifold gaskets? It kind of sounds like you might be referring to both. Either way, replace them all. Like Avern said, you can get the part numbers from SNG Barrett. Or if you do a search on here you will be able to find the part number for for the Feldpro gaskets that fit and where to buy them. I think they are a lot less expensive than the OEM ones.

 

 

Looking for Seals for ITM Tuning Valves.
Would you recommend replacing both upper and lower? DTC #'s P0171 & P0174.
Thanks for your help.

Absolutely replace both of them. It only takes about 5 minutes total and the o-rings are only a few dollars. Very cheap and easy to do, so why not do both, especially if your car has the old style yellow o-rings? The newer style green ones and more robust.

 

I noticed that you have changed the manifold gaskets and are now looking at the IMT's. The x-Type is notorious for vacuum leaks at the PCV hose, the brake booster line and little known but the dipstick area.
Have you checked those areas.

 

You are all great and very knowledgable!
