Injector Seal Replacement - IS220D

How to replace the bottom seal on an injector when the injector is blowing (you will hear it blowing with the bonnet open but the smell will probably hit you first when driving)

Great post Monocle. Saved me a lot of time and money. My injector came out after 40 mins of gentle persuasion so not to bad. Found best way for me was to get it turning first by lots and lots of gentle tapping with a hammer and socket extension. Then levered up slowly with a large screw driver. Only caveat I would add was don't tighten fuel lines till everything aligned properly. Apart from that thanks again.

Hi both, apologies for the delay in a response. Firstly, as this was a pretty instant failure, the car just went back to normal performance. I don't think that it had been blowing more than a few miles. The smell hits you straight away.

Glad to hear the job went well. I've had to do it again since so I will update the guide with some additions and your comments.

Hi. .did it increase your mpg at all? I have 1 injector not spraying enough fuel and the 4 th injector spraying too much. .I'm only getting about 28mpg on combined driving. .

Hi Monocle,

Can you share the info about where you are able to find the parts that you used. I searched in eBay & other auto parts sellers, but no luck.

Thanks
