The smoke is the rubber that used to be there, it's working. If you really want pm me and I'll do them for you.

if you didnt, flip them inside out so you can really see what ur doing. I used a bench grinder and the seal over my finger. I dont recommend it b/c of saftey but i did it :)

I've yet to see "bored" injector seals that didn't turn out shitty.

Fit the seal over a Dremel sand paper drum, and lightly spin the outside of the seal against sandpaper or smooth concrete. Amazingly, you remove a balanced amount of material. Instead of flailing around with your dickbeaters trying to halfass the re-bore so that they fit DSM 450cc correctly, you just put a slight taper on the outside of the o-ring so that it can't help but make a good seal.

use the sanding bit wit the heavier grit. On my they went about half way and then the same problem accured or the seal would just spin around. At this point take the seal out of the IM and flip it around and start grinding from the other side.

Is it true that Zdyne sells the seals? I thought I read it somewhere. Anyway, I used a grinder and kept on checking for propper fittment.

i just used a cordless drill and some big drill bits, held the seal with my fingers and went through the inside of it a few times with large drill bits, they turned out perfect...

imma go try the sandpaper trick tomaro to bore the outside of the seal down

Re: problems boring injector seals
 

I stuck those seals inside a socket and stuck the socket in a vise, so they were pretty loose fitting inside (Just enough to hold it) and used the dremel, then stuck that same seal in a smaller socket, and did it again, they turned out perfect (except for the one that snapped but I used it anyway and it doesnt leak). If you ---- it up you can buy new seals at napa for $10 and they come with o-rings for the top of the injectors and those little plastic spacers that hold them from the fuel rail.

wow, you gouys have problems with this.

I can give you a couple tips. Whoever has the green-ish seals, (NAPA?) they are way firmer than the black OE ones.

I hold the seal with 4 finres around the outside while I bore out the center with a dremel sanding drum. Hasn't failed me yet. They turn out great every time.

Put the seals in the freezer b4 you do it. It helps it hold its shape as it heats up
Work on all 4 at once, cycle em so that they cool down and are not as soft
Check the size on the injector often so you don't go too far
Start with the green ones they are the best
If you can't hold em, put em in an IM with some RTV to hold it

Re: problems boring injector seals
 

I tried boring out my first set of seals, and they were warped with uneven sanding. Then I got smart... bought a THIN $0.78 boxcutter knife, extended out the blade. Take the blade and place it at a 30 degree angle inside the seal. take the knife and rotate it about the inside of the seal w/ slow, light but even pressure. it'll take that lip right off and not warp the seals. you also have more control over how much is removed. You'll see thin layers being removed, similiar to putting an eraser in a pencil sharpener. take less than 5 mins per seal. Follow?

Re: problems boring injector seals
 

Grinding the outside is still the easiest; you don't have to stop and test fit if you taper.

Re: problems boring injector seals
 

JD, your idea is the best yet. I'll have to try that the next time. My TT injectors came with the right size seals, but he doesn't seel them anymore. I heard that those injectors have failed on people. We'll see ;D

Re: problems boring injector seals
 

wow am such a dumbass
heh

did the sandpaper thingy
each seal took 30 seconds:)

thanks alot guys

Are you serious, its not hard. Just take your time and sand the bitches down with a dremel. The "take your time" applies here alot because you have to make sure they fit snug on the injector and then within the port.
