Not too bad of a job. After cracking my second injector in under 10k miles I decided it was time to upgrade a little bit.

Fantastic turn around. I broke down on a Thursday and pulled the injectors and had them to Texas in the overnight on Friday. They were back to me the following Friday as promised and now I am back on the road.

I of course took a diesel bath so I changed the oil and filter and I will change it again tomorrow at lunch after I drive to work (60 miles).

I haven't driven much but I was a little concerned at the large amounts of blue I was blowing when I first fired it up after doing this job, but after a couple minutes of idling it cleared up, it blew blue a little more under light throttle but it was all cleared up within a mile...so I chalked that up to burning off crap from the installation.

I was babying it a little bit and had my SPDiesel box set to 1 (the lowest) and I hadn't touched my boost fooler so it was still set to max...I pulled out on the major highway and was accelerating quite slowly when it start blowing huge plumes of black and I was thinking ohh no what have I done! After I stopped and filled up I turned the box back up to 3 and drove the truck they way I would normally and no black smoke (which is good for me) so I figured it was a strange combination on the boxes that caused my cloud.

Overall I think I am happy. The truck is back on the road, it was easy job (resources here helped with pictorials when I got a little stuck on wiring) and it was only about 5 hours (2 hours tear down and 3 hours rebuild including an oil and fuel filter change). Best of all...at this time...NO LEAKS, NO CEL! lets hope it stays that way

 

How does the truck feel compared to before?

 

Well I am still a little worried that I might have other issues...it blew blue again for about 5 minutes when I started it up this morning.

Other than that though, driving to work I noticed that I was running 4 MPH faster for the same RPM than I used to. Which means when driving at the speed i usually drive at I have a noticable drop in RPM. Also the truck seems quieter when rolling along at 2k RPM, but it does idle louder and sounds more like a traditional diesel when sitting in park.

I'm hesitant to say all is good until it stops blowing blue so I'm going to give it another couple of cold starts and see if it clears up for good.

 

Um...huh? Injectors changes your gearing????? Lost here????

 

maybe your torque converter wasnt locking up earlier and now it is

 

I changed injectors from stock for Formula 1 40HP sticks and I am saying that I as far as noticable changes in the truck that at the same RPM as the old stock injectors I am now runnig 4 MPH faster.

It also appears the blowing blue has subsided, I just had the truck out again and it didn't make a single puff at start. I was concerned that since I changed the injectors because one cracked and I took an oil bath that I might have cause some additional damage which would cause the oil burning at start up but it appears the have gone away so I am thinking it might have just been some amount of break in time was needed with the new injectors.

 

What he's saying is that's not possible without changing the gearing. If you went 70mph at 1900 RPM's before, the injectors won't change that.

 

Perhaps I didn't as much attention as before or perhaps my old cracked injectors required more throttle to maintain a speed.

Either way I am happy with them.
