Diesel injector removal

There we go - don't go doing what I did! haha.. as seen in the pics I used fine wet and dry on all of the injector's body that goes inside the engine - thankfully not a costly mistake!


Jokes aside this sealey tool is £40, new seals £8, and as always messing with injectors is playing with fire.. Would I be a fool to leave a recycled washer in a dirty hole or just take the time needed and splash the cash on the tools?

By the way, my MPG have increased from 55.1 to 57.6 on the trip computer (I drive like a grandad and these are leveled out readings - same trips/routes over a week).

Many thanks Noel
 
A thin strong rag and a screwdriver - its not a good job at all, the seat wasn't spotless I hoovered the hole and visually checked afterward for any loose debris. It has worked but it all needs doing properly. Silly question, or is it - where dose the injector inject the feul from? I didn't see a hole!?
I'm guessing the tar stuff is cooked oil, my turbo is leaking slightly so this probably added to the tar..

How to the professionals clear the seats? - some kind of plug polishing tool? Surely anything too abrasive will take material from the aluminium seat?
 
Slightly embarressed guys :forehead:

So, I knew I had a leak as some goop reapeared after buying the car and cleaning it off. Just recently I've not been able to start the car when hot, messege warning light and beep of Injection fault. SO - I investigated and gathered myself a bloody good handful of copper washers from the garage.

Here we go:

For anyone who is interested - Pinch the injector clip here to remove it properly.


I removed the hard pipe on the top and swung it out of the way to let injector out.


Lovely injector :crazy:



Cleanish - I would have done a better job had it not been getting dark, heres the worst bit! - I had to use the leaking injector as my handful of washers were waaaaaay off!


Assembled.

So, verdict - It starts quicker, sounds quieter (I didn't even notice it was louder than it should be), starts from hot. By the way the method of removal was:
Undo electrical plug, undo injector clip bolt (size 45 Torx) slightly (it was relatively loose) - a turn, put plug back on, start engine, heard a slight air noise, stopped engine, took off electical plug again, loosened hard pipe on top and swung out of the way, removed bolt & clamp, wriggled injector out and cleaned as best as possible and re-assembled.

So, I will be replacing this old seal ASAP, but I'd like to know your guys views on the pics and any advice you guys have on it!?

Cheers!

Scott
