Injector question

[spubar44]

How do i know if my injectors are bad. I hear everyone talking about when they hammer down they blow out black smoke. I hammer down and no smoke comes out. This is my first PS and not sure about alot of things but learning. I always think i should have more power, but i don't have any engine lights and just wanted to know since mine has about 205,000 miles now. Thanks

You get smoke when you do some computer work to your engine. Like a chip or programmer. That is if you have a powerstroke though.

well most of the boys that get smoke have chips or tuners. if you injectors are really bad you will know because it will run rough and you will "normally" get a check engine light, but not always. 205,000! your truck is still a pup! lots of life left!

Do you turn the edge all the way up?

Injectors should be serviced after 125,000 miles. I am in the middle of cleaning and upgrading my injectors, I could not believe the crud that was inside of them. I am upgrading the amount of fuel they can spray to about 160cc's, stock is about 100cc's. Three of the injectors were plugged, only spraying out of one of the six
orifices.

jeff, how are you upgrading them, and is it hard to get them out and clean them. or should they be replaced? I am pretty sure they have never been cleaned or replaced.

Not that difficult removing injectors, hardest step so far is opening injectors up, quite tight.

I am still looking for a machine shop that will machine the internal part that increases the amount of fuel that they will flow. Local machine shops seem to want $900 for this. I took metal shop in high school, with a metal lathe, I could get it done in less than an hour. PowerStroke 7.3 Injectors they sell machined parts, next time I do this I will get the parts.

Get everything clean and install new o-rings is simple. While the truch is down, I am also making a better Y-tube.

Jeff,

Are you in Southern CA? I saw your photo album and one photo looked like it was taken at a bar/restaurant in Julian. I am interested in cleaning my injectors but since it would be my first time it would be nice to have someone standing there to make sure I do not do something stupid. I could provide you with some for your time. Thanks. Rob
