Hi all dose anybody know where I can buy injector seal kits from for a jaguar xk x150 2006 ? Thanks in advance

 

These guys sell good parts. This is for 8 kits, denso injectors, which are used on the 4.2 engines. NA is 4 port, SC I think is 12, but it doesn't matter. Kits fit all Densos of the Types we have. Orings are viton, top and bottom. Note that the filters on mine seemed to be rotted due to age, so examine them carefully and replace where called for. Examine all eight injectors, if they've been in a long time. Some people use this as an opportunity to have the injectors professionally cleaned and rebuilt, usually for $25-30 each. Probably worth it if they've been in there since new. Definitely do it if there's rust or buildup on the face of the injector port surface.

Very important: There is a flat ring around the top (fuel rail) end of the injector. Make sure that's installed, to hold the top oring in place. Lacking it, the ring will slip into the fuel rail and cause a potentially destructive fuel leak. When you insert the injector into the fuel rail, use a thin "just enough to be shiny" coating of motor oil so it slips into the rail. No silicone.

 

@panthera999 thanks for a great write up but will these guys post to uk ? M8

 

Don't know. But there's got to be places in the UK who sell these. That said, if an owner is uncomfortable doing this simple job, send the injectors to a rebuild house for cleaning, testing and repair.

Should include the four items below. Important that both top and bottom o-rings are viton so they're not affected by heat or fuel chemistry. Blue fatter one is at the top, green at the bottom. The old filter can be removed with any appropriate screw-shaped tool insertable into the filter. New one is tapped gently in.

My experience was that the filter in my 70K mile, 11 year old Densos were partially rotted away, so definitely be prepared to replace them. The pintle cap should also be replaced. Again, examine the flat retainer ring on the fuel rail end, and replace if broken or absent.

 

@panthera999 once again great information really appreciated m8 thanks for your time
