How to replace the plastic injector seats

Hi guys, i want to replace the plastic sleaves that the injectors slide into on the cylinder head of my 1.8gti. There is what looks like alan key shape inside the sleaves but i wanted info on extraction b4 i tried it incase it brakes up an goes in the head. I hopefully want to do it without taking the head off. All help is welcome, cheers mick. 

You'll need a large hex type socket but the collar is probably set solid in the head. When you try and turn the socket it'll either round off the edges or break bits off which fall into the head!
I had to wait until my head was off to replace.

These are the correct inserts for a DX head.

Hi Mick I changed mine with the head off but I was lucky and mine unscrewed without any problem I used a large Allen key if I remember correctly. So maybe you could remove them with the head on.
 

thanks guys, i bit the bullet an stuck an alan key in an to my amazement 2 were really slack, as in i unscrewed them with my fingers, 1 was nipped in tight but when it was loose it was fine an the other was a bit slower coming out but its out im well chuffed, there actually more solid than they look.
now where do i get a new set from, i actually only 'need' 2 but whats the point in that lol
Dano, is that an ebay job or is there some1 on ere that sells them? cheers again for ur help fellas, much appreciated

The ones that I got were from VW Heritage. There are two different types so if yours look like that then use the part number on the label in the photo. 

Glad they came out for you! 

I loled theou vw heritage and they wernt listed, i tried the part no an name an got no joy

Double check wich ones you buy.   I'm sure there are two types depending upon age

There are Jim, the ones in the picture and a shorter, stubby set. 

Mick-d-, give them a call. It'll be much easier. 

Hi, yea its def the 1ns in the picture, i was going to buy the other shorter 1ns on ebay because it was the only set for sale until i took them out an saw the picture above, ive got another engine that im going to look at tomorrow as i said 2 are fine so if there is 2 gd 1ns on the other engine ive won a watch, otherwise ill give them a call, whats the price on them?? 

I had a look at the other head which was off the block, no cracks in any of the 4, i thought brill could i get them out?? Could i f:;k, anyway i then tried to feel from the inlet holes an relised it was the other valves, the short 1ns, so i want that bothered anymore that i couldnt get them out. Called up vw heritage, there not in stock an delivery is 3 weeks still- there only £3 a piece an the car has been in the garage for the last 8 years so i suppose it can wait, anyways cheers for the info guys, hopefully it will be on the rd for the summer, ta, mick
