NO. People who bore the seals are crazy.

Just lube up the injector seals nice and good with oil first. Then set the injectors in and tighten your fuel rail down. The rail will press the injectors down no problem. I wouldn't have dreamed of boring my seals first. There was just no need for it at all.

 

bump anyone else?

 

Bore the seals. I tried just forcing mine in without modifying the seals and I had leaks.

 

Strange. Mine were also DSM black-top 450's. Maybe there are different types? All I know is that I personally didn't bore my seals and the seals didn't leak a drop for the 8 months that I was running those inectors.

 

You guys are still using DSMs...I thought LanEvo injectors would be main stream by now. 560cc ownz me!

 

i found that running dsms and forcing it in i had quite a few leaks. maybe im just unlucky but im gonna run rc 550s now

 

I have put DSMs in many times and always had to bore the seals. You want them to fit like stock, not be forced in.

 

i broke a seal once, and went to the auto store.... they had a little kit (I think it was Borg Warner) that came with various sizes of injector seals.... just a thought it bailed me out plenty,.

 

U HAVE TO BORE THE SEALS

i have the DSM 450cc Blue tops on a Z6 manifold, (all honda injectors are the same outter dimensions)
and i tried with oil , and no luck, the gasket was too cramped and was bad, too tight, u can strip the little olts holding the rail, then ur fucked

go buy a dremel , or borrow one

they have this sandwheel, that is like 1/2 big , thats the perfect size...
bore the seals with that, and place oil and now u can put the injectors in... will fit like a glove

this have done 4 times, and works like stock, follow my instructions... if u try to put them without boring, dont come back and bitch it didnt work

 

man there was no way mine were going to fit in without boring. Just bore them out...its not hard at all.

 

I had to bore mine out there was no way they were going to fit.
