Injectors yay!!!!!

[Philv]

Hey, I'm sure this has been asked before, but I'm a little irritated to look after the cloud making my truck did today. Ok, so I need injectors bad. Truck has 266k on it and only 70k on this set. Since I have done numerous hours of research, I know I'm going with LDS. Can I run 30 over injectors on a stock tune? I have been told my trans won't handle 30 overs and tune. I know the trans will be next to go as it does act up under hard throttle. My main goal is 30 over injectors, 64mm turbo, and roughly stage 2 trans. I just want the truck to be fun, but still dependable. I know I'm rambling, I'm tired.lol

You can get buy on a 100% stock tune I would think. It wouldn’t be ideal. If you had it tuned you could get it back to stock power if you wanted. You can also go with the SAC style injectors but you will need a tune to get it to run right.

I've never been a fan of small injectors like +30%. Might as well stay stock. You can bend your rods with stock injectors if you want. Something like the smallest SAC injectors (about +45%) are another story, as the SAC injectors have a lot of advantages.

If you run SAC injectors, you will want a tune. You can have that tune make stock power, or a whole lot more, depends on what you want.

For your goals, I'd do either stock injectors again or the SAC +45%. If you want a bit more headroom for future growth, you could go to a +60% injector (SAC or the normal VCO).

A good tune is only a couple hundred bucks, and that will be the biggest performance per dollar mod you do. Don't try and skip out on a tune to save a few bucks now and end up with injectors you regret later.

If your looking to go 30% i would recommend spending a couple extra dollars to the SAC45. We are selling a ton of these injectors with all smiles! Let me know if I can help.

Will do. I'm gonna do it right the first time. Cups, lines, lift pump, and all rubber fuel lines. Hopefully here soon I can get a loan to get it done. Damn truck is like a chimney at a light.

No need to replace cups. Just pull. Clean. And reseal.

They have 266k miles on them and 3 sets of injectors have been in them. Just to be on the safe side, it's all getting changed out.

Mine had 310k miles and 4 sets of injectors, still worked fine. They are stainless steel; the heads erode around the cups. If you don't somehow mar one, they never wear out.

Really, I've been told by several shops to replace them. Even when I do injectors on class 7-8 trucks, we always replace cups.

I always replace cups on the PowerStroke, because the cups are copper and don't last. But these are stainless, and I have never seen one fail from age. I've chewed a few up in a vice removing stubborn injectors, and seen some where people hammered them in and borked them. Do what makes you happy. If you'd feel better with new ones, then go for it. But I think you will be surprised with their condition when you pull them out.

Someone's been getting "inflated-parts-cost-add-on" advice....

Dave is right on all counts.

 

[Chevy1925]

Listen to dave, he is right about this. just be sure to pop each one out, clean all the old loctite off the cup and the head, then re-seal with the new injector. alot of guys like the green loctite, i still use the 272 since i have a damn 50 dollar bottle of it :roflmao:

 

[Brent@LDS]

No need to replace to cups, they can be reused without any troubles.

 

[Philv]

Ok, I'll take y'all's advice. I won't replace the cups unless they're bad. I know where to get them locally so I don't have to deal with ordering them.

Just curious, I did some research on changing injectors, and the guy had same white smoke problem. All he did was change the nozzles. Is this a real fix for the smoking issue? I don't have diesel in the fuel, and I believe all my solenoids are functional. Is the nozzle where the ball seat is?

 

[rcr1978]

Ball and seat is under the solenoid, nozzles will do nothing for that. The ball and seat cause high return rates. Worn nozzles cause leaky injectors/overfueling/idle haze.

Just buy new to much work involved dicking around throwing new nozzles on, it's a shit job if you clean everything properly and really shity if you have to do it twice.

How many miles are on your injectors?

 

[Philv]

Roughly 70k miles. The guy that I purchased the truck from gave me all receipts and this set was put installed in 2010. In 2012 they started failing again. When I put amsoil injector cleaner in, it clears up most, but not all.

Please listen to the previous posts , Bret has remans for $1700 , which are real remans , not just shot with cleaner and put in boxes . These guys just want to help ! I also wonder how clean your fuel system is , water in tank , road crud getting in sending unit , good filtering system ? If previous owner got 150000 to 180000 out of oem , the other two sets didnt go very far , I just hope you make the right choice . Good luck !

 

[bigmackmiller]

Just curious do you guys always pull all the cups, or just if one pulls you reseal it?
