1st pic: The secondary oil injectors? Anyways the part where the blue hosing goes into can be moved a little. Like I can jiggle them around a little. Not really lose, but I don't have to try very hard to move them. They only move like 1mm or so. Is this a problem?

2nd pic: If I end up running premix and use bolts to block off the oil injector points do I get to get rid of all this? I'm beggining to think that these blue hoses carry coolant, but why would coolant be getting injected with oil into the engine? So what do they carry?

3rd pic: I think someone stepped on my injector...The floor is not a great storage place, even if noone goes in that area..I highlighted the tip/cap or w/e it is that was cracked. Where can I get another cap thing? It looks like a cheap simple part, but is it even needed uncracked? The red is pretty much the crack.

Also anyone know where to get cheap fuel injector seals?

The blue lines carry air, they are vacuum lines. The things that wiggle slightly are 2 of your oil injectors, they actually screw in, I don't know if they're supposed to be able to wiggle at all. And if you were to go premix, you'd block off the 4 oil injectors with bolts, and get rid of the vacuum spider thingy, and block off the large vacuum nipple that all those come from. In addition to getting rid of the OMP.

I think.

As for the cracked thing, I believe that's called a pintle cap, but if you're talking to the parts department at Mazda, *I think* they may call it an air bleed, but I wasn't sure if me and the parts lady were on the same page.

And for all the other injector seals, you can order a kit which has the o-rings and grommets from pep boys or mazda, or maybe any other auto parts store. I think pep boys charged me something like $7 for each injector seal set.

What is premix and what advantages/disadvantages are there to it?

I dont mean to hijack...Im just curious.

jhammons01

Xstreme just do a search on premix. It is a well covered topic. Its also in the FAQ

Smog, I paid about $3 per kit for injector seals. There are three pieces. Upper and lower grommet, and an o-ring. You need all three if you've (and you have ) pulled your injecters out.

Gatlin is right the blue lines are vacuum. Don't know how to fix the broken injector. The caps (the large nut on top of the OMP lines) should be tight and not move. If you had a vaccum leak you may have just found it.

The local place thet cleaned my injectors replaced the pintle caps as well as all the orings and upper grommets. You might want to call around to some injector shops, as they have or can get the pintle caps.

So just the nipple moves a little, or the entire injector? If it's the entire injector, that's not good. Tighten it. If it's just the nipple... dunno what to tell you. Other than to encourage you to switch to premix and get rid of all that stuff.



Yup. And the top of the engine looks a lot prettier without all that vac hose.


I don't know much about injectors, but if I were you I'd replace it. You should be able to find a perfectly-good used one on eBay. I just had a look at our f/s section and looks like no one has any right now.

Your injectors: 88 13B Turbo, high square offset, 550cc, purple, 195500-1370

You can measure the impedance of your injectors with a multimeter to find out if they're high or low impedance. 2-3 ohms = low and 12-13 ohms = high.

As mentioned before, they are the oil injectors.
And no, they shouldn't move.

Yes you would use bolts to block them off. The length of the 4 oil injectors are not the same, so meassure hem to make sure they do not pertrude into the engine.
The blue lines are vacuum lines.

On this pic you can bearly see the oil injectors blocked off. The "rats nest" was removed. I only kept the fuel line part.

On this pic you can see the OMP blocked. You can also get a block of plate.

As mentioned, they are called "pintles". They are $2 ea. at Mazdatrix.com

On that same page you can find the "grommets & O-rings".

I'm kind of upset with mazdatrix at the moment. I still need to call em because its been a week and my uim gasket hasnt come in..When I ordered a short shifter form them it came in 4 days. Anyways the injector seals are 3 bucks each...that means i need to spend 12 dollars? 3 seals x 4 injectors. Thanks for the pintle thing. I didn't want to buy a whole nother injector when all i needed was a stupid little tip thing. Also a quick question about you premixers: How do you measure how much to add? I know I want a 100 to 1 mixture of gas and 2 stroke, but do you carry a measuring cup or somthing? Also if I get rid of all that outlined hosing in picture 2 do I need to block off the UIM hole where that black hose circled goes into?

EDIT: I just checked mazda trix and its 3 bucks per O ring. Thats 3 O rings per injector X 4 injectors. Thats 36 bucks in stupid seals??? Is this right?

if you decide to send out your injectors to have them cleaned they may give you new o-rings as well so you could look into that as an option. also, they should carry replacement pintle caps if they are a decent injector shop.


for premixing, a good rule of thumb to use is about 1 ounce of 2 stroke oil per gallon of gas. i carry a couple of 12 ounce bottles and fill them up with oil and add one bottle before filling up with fuel, 12 ounces of oil with 12-13 gallons of gas will get you near a 100:1 fuel/oil ratio and will work just fine.

Find a container that holds just the amount that you want to use. I found that the old Marvel Mystery Oil bottles would *just* hold a little under 13oz. So I'd keep a bunch of those in my spare tire well.
Then MMO came out with new bottles. I can put 32oz in them with room to spare. That's two 16 oz fills right there. So now I just use two of the new big bottles instead of keeping a dozen of the old ones.
A 100:1 ratio works out to 20.5oz per tank, assuming that you run your tank right down before filling up.




Yup, just put a vacuum cap on it. You can get them at any parts store.

I have the problem of keeping my tank topped off....guess I'll have to break the habit

As said above, if you are looking to replace the injector orings, grommets, and pintle caps just send them to get cleaned. All that stuff I listed above for the injectors will cost you about $6-8 per injector while cleaning is only about $12-20 depending where you go and they include all those things as part of the package.

BTW from the top of the injector down is 1 small oring, 1 grommet another grommet on the bottom with beveled edges and then the pintle cap.
