X-type Jaguar
Looking down the main pipe you will see an amount of carbon deposit which may or may not
be oily – it will certainly be VERY dirty stuff so take precautions to prevent damage to you,
your clothes or your car.

Gently scrape excess carbon and gunk off with a blunt knife, I used a small flat screwdriver to
prod around the valve housing which was particularly badly clogged. An old toothbrush and
some white spirit got rid of the greasy residue, dry off with paper kitchen towel.
Although now clean the surfaces were blackened so I used some very fine steel wool to get rid
of the surface patina and leave a smooth shiny surface which will hopefully aid the flow of
gases in future.
A quick wipe over, test the valve was still clean and free to do its job by winding the spring as
before and then re-assemble.
Once the gears have been aligned, the retaining cover just needed coaxing back on and then
it’s a simple re-fit - 2 x bolts, 2 x nuts and the hose clips. Its tight in there so watch your
knuckles!!
