injector seats

hi can anyone help i have taken the engine my mk1 1..8 8v 1983 project and have found the injector seats in the head  are broken by looking through the ports you can see .also the shape of the injector seats are hexagonal like a 50 pence bit is this correct ????? can you buy new inserts ??? if so how much  cheers  guy

Hi gemmaguy,

yes you can buy them - if your dealer stocks them AND knows what he's looking for!! (I went in and was told they were obsolete. Jellybelly did me a favour and got me a set and posted them to me.)

The '50p' shape is a 12mm hex fitting - available from halfords and other motor factors.

The material in mine was like bakealite and it cracked off when I changed the injectors. The only problem I've got is that I've tried to do the 12mm hex removal but its spinning in the hole so I've left it, sealed with some silicone!!

If you've got the head off you're lucky cause any debris won't drop into the cylinders!! Change them while its off. Only about £5.00 or so for a set of 4!

hi do these injectors just have an o ring to seal coz the the rubbers i took out was in the shape of a 50 p and they was really tight to get out .

Yes they are round and with a bit of grease should slide on easily into the recess that they sit in.

Mine were a right b*^$&"(d to get out, even with all of A5OPY's (considerable  :wink: ) weight behind a screw driver! Thats probably why the seats theyselves broke off. That and age.

hi i have taken the sleeves out where the injectors push in 2 and i have rang vw and they told me that the part number i ave is for a later engine and not a dx .the head i have is off a 1984 will my injectors for a dx engine fit these sleeves .i have pics but will have 2 email them to someone that can help cheers .
