Injector O rings

ad_car_08 · May 6, 2019, 23:21

Was going to attempt to fit the 2zz yellow injectors earlier. Whilst looking for a "How to" I read that some replacement o rings are recommended.

Does anyone know where id get them from, to fit the yellow injectors? Apparently they're slightly thicker than those needed for the 1zz green injectors?

I've found that they are interchangeable. When they come as part of kits, there is no difference that I've seen. Never had any leaks after swapping injectors.

Older O rings will look a bit thinner as they deform over time.

You can get them from Sealforce (they have an ebay shop). I bought 8mm x 2mm Nitrile. (fuel resistant). Might as well buy a few 'cos they're so cheap!!!

Only difference I noticed when I got the 2zz injectors was the colour, orange rings on the 2zz ones. I got some new black ones with the full engine seal kit for the rebuild and they didn't leak on the 2zzs when I fitted them.

Is this the only size i'd require?

So long as you don't need the fat base seals as well.

Worth getting as a belt and braces approach? I don't fancy risking any kind of leaks.

I see sealforve are on holiday and not taking orders, so I looked on fleabay...99p per o ring?...Is that right?

Check the price for ten!!

If the base rubbers are flexible, they'll be fine. They seal air not fuel. If they've gone stiff, might be worth getting a set (won't be from Sealforce though).

How many do you need?
I have some of the seals that Carolyn uses.... she was kind enough to give them to me a while back when I was doing the turbo build
Happy to post them to you FOC if you need them.... think there's a set of 4, but will need to double check

That's very kind of you, thank you! If I just need 1 seal per injector, just the 4 please :notworthy:

No worries, I'll dig them out tonight... might actually be at home for a change
