What type of injector grommets are you guys using on your b series. I'm talking about the big rubber seal that goes into the intake manifold, and then the injector seats into that?

My original b16a had like 3/4" thick rubber things, but i had to hone them out for my 450cc's. I'm going back to stock injectors now and got a new set of grommets, but it came in a pack of 8. ONe very thin ring that doesnt seal on the injector, and then one that does seal on injector but is about half the size of the original one. And yes they are all oem new honda in the bag. Are these a new style replacement? Which one goes into the manifold first, the loose one (spacer) or the tighter soft one????

 

stock injectors should still work in those rings. well my reasoning is i sanded down the inside of the stock ones for my 450's back in the day...but stock injectors still fit a little snug using the same rings. if the wiggle a little its still fine.

 

WEll thats an interesting thought, but mine are too loose in there

 

how loose is loose? (i ask girls that a lot. lulz.)

as long as the injector doesn like move back and forth lol, it should be fine.

 

yea that what it does...

I've never seen these new style though where there are two different pieces for each injector

 

anybody?

 

should only be one ring. the one that fits into the intake manidfold. put it on the injector first. then into the manifold

 

first on injector then mani. You can buy a kit from Napa or Advanced Auto and they sell the kit with the small o ring for the end of the injector. Worked great.$5 each

 

I've seen the kind that you have with the smaller ring and the larger ring, but were on a friends motor. The only ones that I have ever used, and also just bought a new set from Honda for my ITR are these...

 

^^ Those are the ones i have but they also came with the smaller ring which i thought was a spacer...

They are a spacer, put the spacer in the intake manifold before the injector o-ring, generally the spacers do not have to be replaced.
