HELP: Denso 550 leaking
 

Just fitted the 550 denso injectors. With adaptors. ONE is leaking.

Is there supposed to be an O ring at nr. 1

And - where does nr. 2 fit ?

The big O ring is from the old OE injectors. Dosn't fit anywhere.

It only seem like one is leaking... ?

/Jesper

yes there should be an o ring at no 1 but no 2 i didnt have that and you dont use the o rings from your old injectors.
kit seems to be different from the kit i had with mine

david

There is a O ring just below nr 1 - but the adaptor has a slight - don't know what it is called in English - there is a slight difference in the size of the top from the middle... ? (know what I mean?)

The adaptor

There shouldn't be an o-ring at #1. The one that is already there is sufficient. Those collars are chamfered like mine are to allow them to be fitted to the injector without damaging the o-ring. I can't quite make out what you have circled in #2.

David, Jesper has Phase 2 fuel rails which require a different adaptor kit.

If you have vernier calipers measure the ID of the collar.

on i see now the o rings are there under no 1

the white plastic clip fits above the oring on the nozzle end and is used to push the o-ring fully down into the rail. I did this to prevent the black plastic part from being squashed into the rail. It's just a small slither of nylon airline pipe.

I also replied on 22b, but you should look out for leaks from the body of the injector, where the plastic is moulded aroung the metal body od the injector. I have had a number of examples of this, especially on injectors that have been abused to remove them from the rails.

Also make sure you grease the o-rings (not sure if I did yours Jesper, I usualy do before sending them out) as this will prevent them from twisting round as you fit them in the rail.

They are greased nicely :)

So all orings are there, meaning that the injector is damaged... Nice- especially when people you buy them from says they are tested and cleaned... really nice...

/Jesper

Would new o rings do the trick? or where do I buy one new denso injector?

I should have some more o-rings, I will put together a set and send them to you.

Paul

Will try.. Thanks Paul! :)

Fixed the leak yet Jesper? If not give me a call, had the same thing happening to mine one week ago.

Will post friday. been busy working, getting up at 5.30am :rolleyes:

day off tomorrow, woohoo!

Thanks Paul - Just glad you are helping out :)

If that dosn't work, do you know any that have a single denso 550 ? or do I need 4 new ?

Any news?

sent, you should get them Friday with a little luck

Recieved.. But one is still leaking, so it must be broke....

So check wanted thread, seeking one 550cc denso injector for phase 1

/Jesper

Same thing is happening to my injector....All three are fine but one looks like it has a really minor leak from the plastic moulding. "Jbagh" would you like to buy 4 injectors off me??? Or would you like to sell yours to me?? Thanks
