I'm real happy for all you fellers who are now mixing oil in the gas tank. So if you want to rid yourself of the oil injectors that were working (no interest in the others), I'd be pleased to take them off your hands for a few bucks. 86 thru 88 only, please.

 

Im unwilling to blow on the oil injector to see if it works

Well, will you Suck on them?

 

CosmicButtHairs will. $2 or best offer.


I'll save them for you when I pull them this summer.

 

I may pull them in the following week or so. If i could find a good writeup on removing the MOP.

 

why do you want the older ones? the S5 are better. and replace the S4 just fine. in fact you can only buy the s5 ones now at dealerships. they just sell them to replace all years.

 

Scott 89t2.....I'm just ignorant. Since that's the case, I'll take (buy) either as long as they work. I.E. as DROX mentions, can pass air by blowing into the nipple but cannot suck from the nipple. All four on my 87n/a were shot and sucking oil at a good rate and I have on bad one on my turboii spare engine that I want to replace proir to putting the manifold on.

kep0ne......there are some writeups somewhere....but it seems to me you just have to take the upper intake off to access the oil injectors, pull the injectors out with a very thin 14mm wrench (I just took a 14mm wrench and ground down the excess material on it several years ago) and then remove them. Now I've never done this myself (the permanent removal) so you could go a couple of ways. Install some threaded bolts into the vacant holes, or just reinstall the injectors and plug the oil line port with rtv and the same with where the vacuuum hose goes on top.

The pump itself should be easy. Just disconnect the operating rod to the throttle, remove the 4 banjo bolts then the two 10mm bolts that hold the pump on. I reckon you could make a blockoff plate with a piece of aluminium, by cutting the shape out and drill two holes. Then rtv the aluminium and slap it on. Or ....leave the pump in place and replace the banjo bolts with fully threaded bolts. Seems that would work for me. Never done that, just seems all you really need to do is replace the banjo bolts with regular bolts with solid washers. Maybe some rtv on the bolt heads.

 

hey i just resently aquired an 86 rx-7 with a 20-b rotary,
insted of the stock 13-b but im dumbfounded about the engines any help would be awsome.

 

i just pulled mine off last night, but haven't tested them yet. let me know if you want them cuz I was just gonna toss em...

 

2a+RoN.....I do want them, if.....when you blow into the nipple part air will pass thru it, but if you suck on the nipple...you should feel no air passing towards the nipple. In other words air should only pass in one direction, and that direction is towards the engine end of the injector.

If it passes air in both directions....I don't need it because I've already got four broken ones.

Send me a pm if you want to sell them. Thank you. I'm at work right now and a bit slow to respond.

 

your joking right?? does it run?? how much did you pay??
