If this happens the truck will not start due to low icp. I found this out a couple nights ago while I was looking for a hpo leak after sanding my spool valves.
Is this no start a fact?

Just bumping an old thread. For those of you who have had injector stiction issues....and went ahead and sanded/cleaned the spool valves.....how long did the fix last?

I'm going to have my heads off soon....and since the injectors will be out, I'm thinking about cleaning the spool valves in all of them. My truck runs pretty rough until the oil temp gets up over 90deg or so. I figured that as long as there are no negative side affects...I might try cleaning all the spool valves.......is it worth the trouble?

I havenít cleaned my spool valves, but it has to be better than spending $1,600 on new oem reman injectors. I would definitely do it if I couldnít pony up the cash for injectors.

I have about 50k on mine since doing this and they still perform as well as the day I did it. Factory injectors at around 105k and now just over 150k. Truck starts right up at any temp and runs great. Even on single digit temps. I haven't even bothered plugging it in this year. Just run on high idle for a few mins then roll out. Prior to doing this the truck couldn't move out of its own way till it was warm. If you needed to go anywhere quick you had to have it plugged in, even in 80+ degree temps. Truck would just rev to about 2k then start to miss and pop. You would have to barely touch the throttle to get it to shift and do more than 20mph. If you already are pulling them for other work there is no reason not to do it. Once you do it and keep good oil change intervals and quality I doubt it would need done again. I can also say hotshots and revx won't do chit to help with stiction. I tried it for 2 oik changes before pulling the injectors for cleaning and it didn't change anything. I also tried running it in my other truck for a year to see if it would work long term and still no change. That truck isn't too bad that I have just dealt with it till I tear into if for something else.

Good to know....thanks!! I guess since I'm going to have the injectors out anyways, I might as well give it a try. My truck run OK cold, just stumbles a bucks a little bit until the oil temps get up over 90....so I'm sure there is some stiction going on. Sounds like a really easy job....nothing compared to doing the heads cab-on like I'm getting ready to do. I guess when I get tired of laying on the motor and turning wrenches, I can work on cleaning the injector spools

Is it tho??

The new gen2 injectors we have now are much better than what we had 3+ yrs ago when polishing was the thing to do. Considering the labor is LESS to remove and replace than to remove and disassemble and polish (if we are being logical and actually accounting for time spent which I know there will be a key board warrior that will hit me for "it only takes 5 mins per injector to polish" blah blah blah) the injectors, I think I would lean towards replacing with the new injectors with slotted end caps and all the updates.

I fully understand (frugal tidepod eaters) that you WILL save money polishing your OE turds....sorry injectors, but when weighing the pros and cons NOW, there is a ton more pros with the new injectors that there weren't available 3yrs ago. It is amazing how smooth and quiet these 6.0's run with a new set of gen2 injectors in them. It will make you love the truck again.

I 100% agree, and that is why I have new injectors. I was thinking about folks that are tapped out for money. It is a good alternative if you have more time than money.

But isn't time money??



I know I know. It is a good option for people that want to experiment and get more time out of a something. I just wanted to throw out that the new ones are much better than what we had years ago.
