traffic dci injectors

[rampantreaper]

well i have the dreaded 2.0 dci lump in my trafic, i say dreaded cos altho its done 87000 miles from new by me and has been absolutely perfect so far bar a faulty air flow meter its well known for injectors going down. now it would appear they are almost impossible to get out as the water that drains from the screen fills the injector wells and welds them in. so anything i can do to try to ease this should it happen to mine? was thinking of wd 40 in the injector holes or something?
my thinking is if the water seeps into the threads enough to weld them in then wd40 over a period of time might help?
failing that does anyone no of a good way to remove them or someone that does it? i no of several plumbers that are paying upwards of 1200 to replace an injector apparently!

Special tooling required to get them out only as they are tighter than my wallet !
you can use penetrating oil or cellulose thinners to soak in for a short time to help.

i was thinking over a period of time it might help. they might never need doing but you never no.

sell the screen up now and minimise it i belive there is now a ots that covers the injectors not sure on the rules, we have used a company called pearce bros before.
when they snap though oh dear

They will get stuck in no matter what you do, and lube you put on them will burn off when hot and they have a plastic cover over them anyway which helps a bit.
Done a few and a few pumps as well its a common problem.

The special tool does work well. But well worth a soak with cilit bang. It's excellent at eating away the corrosion around the injectors.

As lemon bobby said well worth a phone call to your local dealer as there maybe a contribution towards the costs.
