check on my fuel injectors please

[wangless]

i bought a rail and injectors (used about 1k) and i wanted to post some pics to make sure that they were ok. and i also have some questions as well. ill attach as many pics as i could because i dont know how to html or upload pics anywhere else

[wangless]

heres injectors 3 and 4

[themadscientist]

what do you mean "ok"? they look like 260cc injectors to me.

[Nathan]

Yep, those are top feeds! Ok, I don't know what you mean by ok either...but I do know they are top feed injectors!

[wangless]

can you see at the top, not the first ring, but the second black piece... it has some cracks.. should i worry ?

[Nathan]

Can't really see You could always pick up new injectors at the junkyard cheap if this is for a KA24E

[wangless]

more pics to come... top feed... they should fit on the ka24e right... sohc engine. if not ... and who wants them...

[wangless]

heres 3 and 4... too bad i cant attach more than one file at a time

[Nathan]

Yeah, top feeds are KA24E injectors, unless they are CA or RB26 I think it is...as for your crack, unless it damaged something inside its probably nothing to worry about. Only one way to find out though! Go plug it in and see what happens

[wangless]

can you see the crack on this one? all four of them have cracks like this all around. should it be something to worry about? and wheres the o ring that i should change.

on the second pic, the second one has some funny stuff on the bottom, it doesnt look normal compared to the others one. whats that part?

[wangless]

"what do you mean "ok"? they look like 260cc injectors to me."

are they ok with those weird cracks? and these are 260cc injectors? i thought stock was 370cc... i learn something new everything from these forums

and btw, thats some quick response! i just posted and then you guys replied!

[wangless]

what the hell is this dirty part? is it the o ring?

[Supafly]

the dirty part is the injector isolator i believe. and the small cracks are ok, those are just spacers to help the rail push down on the injectors to make them seal tight in the manifold and not let them go too deep into the rail. just make sure they don't break when you install them and you'll be ok.

[wangless]

alright, thanks supafly

[NismoRb20S13]

you should get new ones and a new o-ring set before installing them they shouldnt have those cracks in them any way they are dirt cheap to get new o-rings and iso's at an auto parts store, just get the ka ones

it almost looks like they started to dry rot or just break down from fuel getting on them

[wangless]

can i replaced the cracked part? theres the o ring, then the cracked part, then the iso right? so whats the name of the cracked part?

[NismoRb20S13]

that black cracked plastic thing is the iso

then there is the o-ring to the fuel rail on top, then the iso goes on

then the seal to the manifold is the bottom seal

so you need to change all 3 when you re-install its just a saftey issue really and the ka already likes to leak at the injectors so wy riskgo to the auto store and get

2 - o=ring kits *(easy to cut the oring if you put it in crooked so if you mess up use a new one)1 - injector seal kit *(harder to mess these up)4 - new isolators (might come in packs of 4 but i doubt it)

and take your time dont force it, and your rail is gonna dump a ton of gas everywhere so be prepared and have a fire exingusher handy just in case , and always disconnect the batt first. and torque to specs or youll crack the mani, rail or an injector more likely the #1 or #4 injector.

sorry this was so long it just kept coming to me.

oh and when you take off the 2 bolts holding the rail on dont drop the 2 washers down in the engine your gonna need those.and take off all the fuel lines before unbolting it.

[wangless]

alright, thanks. how much do you thing the o ring, seals, and iso's are gonna cost me?

ill take my time. dont want to have even worst mpg than i do now (15mpg)

[NismoRb20S13]

they are cheap like 3- 5 bucks a pack of 4 oring or 4 seals

i forget on teh isos not much at all

[wangless]

so i went to kragen today, expecting it to be pretty cheap. 2.49 for a seal kit, which comes with the top and bottom isolator, its what they called it. then 5.99 for each o ring. im like WTF ?! that totals to about $6 + $2.50 = $8.50 x 4 injectors = $34? yeah, i think its $34. damn, i thought it was gonna be like $10 TOTAL ! any one have any suggestions to get cheaper o rings and isolators? thanks.

[NismoRb20S13]

i dunno man autozone here in ohio had everything for under 20 bucks id still pay the 34 tho your talking about the fuel system so there is no room to be cheap.

cause cheap and half assed = dangerous

[wangless]

yeah... agreed on can go cheap on the fuel system. i wouldnt want o have a bigger leak that would case me to like have a fire or anything. but just wanted to know there was anywhere cheaper
