Is there a gasket for the intake elbow?

[lockwood77]

Having got my water injection working (somewhat intermittently...), I notice that is spits a bit of oily water out of the join between the elbow and whatever it attaches to (throttle body?)

That means that air is escaping, so I wondered whether there is a gasket or some sealant missing from the join? I notice that the next join along appears to have a metal gasket, should I have similar at the elbow join?

IIRC it has a rubber type of O ring...

yeah, rubber \'O\' (Or more accurately: triangle!) ring.

[lockwood77]

Can you see it with everything in place, or only when the elbow is removed? I suspect mine is missing!

[RemarkLima]

Only then the elbow is removed as it should sit in a groove if that makes sense?

[lockwood77]

Ah right, I\'ll whip it off and see what I can see then!

depending on the age of the car, the o ring really is quite crap at sealing, mainly cos the plastic elbow warps.  I found mine was leaking here too but found the elbow mating face not flat, so a quick sand down on a flat surface and it\'s ok now

Ah, my elbow is metal, is that not standard!? It doesn\'t look like a Greddy one etc.

Standard elbows were plastic matey... Just check the mating face on a flat surface, it\'s it\'s flat the o ring will work, if it\'s not then you can either have the surface machined or put some dare i say it liquid gasket or RTV sealant on

i have the metal greddy elbow and i\'m sure i still retained my o-ring. But not i can\'t remember!!

[lockwood77]

Ah right, I guess I have some benefit from a metal elbow then! Won\'t bother with a Greddy one now!

isnt the o-ring on the throttle body side

Yeah sits in a nice little groove  but if the mating surface isn\'t flat dont matter if the o ring is in good condition or not, it wont seal

[nikp]

I thought so - i just couldn\'t remember. So, whatever elbow you have, as long as you are running the standard TB, you should have an o ring

[SmbFD3S]

yeah look like this:
