i'm using the top oring (the one that's on the bottom of the clips) that came with the RC injectors. when i tighten it down, the orings always gets smused. is this normal? their oring is half a size smaller than the stock orings.

i'm also using RC's bottom orings (the ones that goes into the mainfold) which is also half a size smaller than stock.

what should i do?

 

they should fit, for my dsm 450's i just used the gsr orings and spacers, works fine for me.

 

Are you talkin about the tiny green O ring that is at the very top of the injector like in this PIC? it's normal for that to get flattened when you put it into your fuel rail. For the bottom O ring that goes into the intake manifold use the ones that RC eng sent you.

 

i'm talking about these....(circled in red)
so it's normal for it to be smushed?

 

it should smush a little bit to seal around it, u might be over tightening the fuel rail bolt to the intake manifold

 

you mean like this?


I got some quarter sized washers and put it between the fuel rail. It looks alot better now

 

lol, EXACTLY like that!! i don't get where u put the washers....can u draw a pic of show me a pic?


is that normal though?

 

Here this should help

 

i plugged in the clips first then tighten them dont, no leaks or problems so far, had them on for about 300 miles now

 

I used metal washers to keep em from smashing as well . .
