Under the fuel injectors,there are black (Plastic?) things that go into the head for them to sit in,and its not the o rings, would you call these Injector Seals? anyways, can someone tell me what they are called, and where I can get a set, or even just one, maybe a part number?, I just pulled the motor on 352/1000 last night, and one was cracked, so I need to get another one. Thanks

You're talking about the isolator, and its not supposed to be hard plastic, its supposed to be rubber. /ubbthreads/images/graemlins/rofl.gif

The somewhat hard black rubber ones that slide over the injector tips and go between the injectors and manifold are are technically isolators I believe but most ppl call them seals. They seem fairly universal. One of mine was cracked so I took one off of a 240sx injector I had laying around.

They started out life as soft rubber but after a while the heat from the head turns them into hard plastic like button. When they harden they would usually also started leaking boost and vacuum. So definitely make sure that the rubber isolators are always nice and soft for best seals.
 

Agree. #1 injector on my car is leaking so badly I've just been lazy to pull the rail off & change them. I've had the new ones for ~3 mths now. I guess it's because I haven't driven the car in a while so it's not a big deal.

Speaking of which, has anyone tried to make something more universal to replace these with? I mean $1.50-$3 times 4 gets annoyingly pricey with multiple 4G63s and not to mention you have to order the stupid things. Surely someone has an idea of some kind of hose or something that can be cut up to use. I mean, it's just a rubber seal that needs to have a similar inner and outer diameter. And maybe something not rubber to extend the life?

Just buy extras and keep them handy. If your worried about spending $10 to keep a spare set in the garage, BUY A HONDA.

I have had to change one at DM meet a few years back. Car started to idle really poor and was SUPER lean at idle and high vac crusing. Ryan Hertz had a few new ones in the back of his car and let me have one. Saved my bacon.

Thanks Ryan.

My point, Terry, is that they are way overpriced, fail too often and are easily lost. And of course, only the dealer has them and never in stock. I'm more than willing to buy a much more expensive set if they can last longer and not get so hard and brittle after a whopping 10k miles. Surely the rocket-science crew has some ideas.

And I never said I didn't have extras.

Napa sells these in a "kit" that includes the o-ring the upper spacer and the isolator and the plastic shroud, for around $5. I just bought four kits the other day and was pleasantly surprised with the deal. Item#: ATM200400

I remember seeing somewhere that someone fabbed up a set from Home Depot Racing parts. I believe they used faucet seals. Kinda ghetto but I guess if it works... Try to Google it since im lazy.

I'm sorry guys but do you realize what you are trying to "fab" up?

I can't believe ANYONE would consider using parts on a high pressure, high temperature fuel system that is not designed for that application.

I have seen too many fuel fires to even think twice about paying the tiny amount extra for factory quality parts.

All I am going to say is good luck and make sure you tell me that something is rigged before I agree to take a ride with you.

Quoting Terry Posten:

Says the man who put rice stickers on his brand new Ralliart.

I'm sick of the Honda hate on this board, get over yourself.

However to get back on topic I will agree, just buy OEM seals or at least the kit from Autozone if they are of equal quality. Unless of course you can come up with some sort of solution that is made of an even better material like Ryan suggested.

I would have let it go as a joke but the caps lock indicates it's not. And I know it's a Mitsu board but still man, it's childish.

I don't think it's hating on Honda to make such a recommendation. I'm a Honda owner and fan myself, and I would make the same recommendation to people who aren't fit to seriously modify a car. It's really damn hard to mess up a Honda to the point of catastrophic failure, so it's a popular suggestion to tell newbs to "get a HONDA".

I think Hondas are great little cars that happen to be some of the most reliable rides out there, and are incredibly tolerable of retarded mods.
