50mm intake injector seat insert removal.

[MZpog 10]

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.

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?

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

I'm confused as to what bit we are talking about? Just curious really.

[Jim 2]

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.

Ahh, no wonder i'm confused, i assumed it was a VR

Other engines are available ;-)

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?

Looks like I'll need to get some more bits from ebay, lol

Inserts out and now wondering if the o ring fits between these bits?

Cheers, you don't have the part number by any chance so I can find some on ebay.

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

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.
