MZpog 10 Posted February 19, 2015 Just got my 50mm intake back from powder coating and the process has melted the bottom of the injector seat/inserts but the top part stayed in place. Fortunately I needed to replace anyway as 2 were broken. They look like they push fit but before I go whacking them with a hammer/drift, thought I best check. I did a search and some look like push fit, some screw fit. I'm confused now as are they also look to be one piece or two piece. Is there a bottom/top part to the insert? Couldn't find any photographs to give me a clue. Any help would be appreciated. Quote Share this post Link to post Share on other sites
Jim 2 Posted February 19, 2015 If they're the bronze / copper coloured things I'm pretty sure they actually just unscrew from the manifold :) You'll need a large sized bit to fit into it then should be able to undo them? Quote Share this post Link to post Share on other sites
swiftkid 1 Posted February 19, 2015 As Jim says they are brass inserts, I used a bolt head to undo them as they are pretty big hex size. once you undo them the full lot should just come out together Quote Share this post Link to post Share on other sites
Jim Bowen 1 Posted February 19, 2015 I'm confused as to what bit we are talking about? Just curious really. Quote Share this post Link to post Share on other sites
Jim 2 Posted February 19, 2015 This is on a 16v (lower) inlet manifold. In the manifold there are brass injector seats that screw into the manifold, which the injectors are then inserted into. Quote Share this post Link to post Share on other sites

MZpog 10 Posted February 21, 2015 New lower injector inserts received today. I assume to fit these I just unscrew the brass guide, push the lower inserts in and then refasten the brass guide, or is there something else I need to know? Quote Share this post Link to post Share on other sites

MZpog 10 Posted February 23, 2015 Parts ordered so maybe I'll be able to give a review of the 50mm intake soon. Steveo, a picture would be appreciated as I can't find one online, nor could I find the page in my Bentley Quote Share this post Link to post Share on other sites
MZpog 10 Posted February 24, 2015 (edited) Further searching found this http://www.ebay.com/itm/MK1-2-VW-Audi-Injector-bushing-kit-with-seals-Gti-Rabbit-Scirocco-Jetta-GTi-/350352201220 ebay link with instructions:- "When installing the fuel injector insulator bushings back into the head, snap them together, install the thin o-ring onto the bottom of the plastic cone before threading them into the head. But use blue Loctite (or similar thread locker / sealer) on the brass threads to lock and seal them into place" O ring at bottom as per Steveo, thread lock as per above instruction.
