Dealer says 2 injectors...yes or no?

[spoonfedblue]

So i dropped off my truck at the dealer last night. I've been having some lack of power issues when cold and it smokes light blue every now and then on cold starts. Anyway, dealer cold started it today and just called, they're saying I have cylinders 2 and 4 injectors that are bad, causing low oil pressure, which is contributing to my hard starts/lack of power/smoke. They want about $1000 to replace them. My question is this: is this an accurate diagnosis? I am a trans tech at the chevy dealer next door, and have no fear of replacing the injectors myself, but at $300 each, I want to be sure that this is the likely cause. My FICM volts(according to my Insight CTS) are always around 47-48V, sometimes 46.5 if its colder. Batteries looked newer when I bought the truck, and I haven't seen any symptoms of weak batteries. I've only had it 6 months, so I don't know the truck that well to begin with, it's my first diesel. I knew I would be looking at something like this eventually, but was hoping it would hold out a little longer. Also, any opinions on wether or not Rev-X will help any until I can save the scratch to buy the injectors? Thanks for the advice in advance, I've never been steered wrong here before.

Oh, and #2 and #4 are in the same bank aren't they?

Yes, they're on the same bank. I would give the Rev-X a try, and use a good synthetic 5w-40. It's cheaper than $600, and it has fixed many injector issues. You'll be out $200 bucks of so. Probably injector stiction, but they could be trashed too. I'll bet on the stiction if it runs like that only when the engine is cold


Be sure you give the Rev and syn oil time to clean the injectors out though. I should clear up in less than 500 miles if it's going to

No doubt I would start with rev x or hotshots secret. Both work and could save you 600 and more importantly.... YOUR TIME!!!!!

Also syn 5/40 is a great idea!!!

Thanks 2006PSDSD and Galaxie, I am gonna get some Rev-X on the way today I think. I have been running Rotella T6 5W40 since I bought the truck with all Motorcraft filters (oil and fuel), roughly 10,000 miles ago. It does seem to be greatly improved when warm, so I am gonna try the Rev-X and keep my fingers crossed. I'm just glad it should only be two injectors, better than 8! Plus they're in the front on the easy side of the engine, so worst comes to worst, and afternoon in the garage and a few hundred dollars should correct it if the Rev-X doesn't.

lucky that their on the same bank...rev-x worked for me, its a great product, i keep some in the garage at all times...if its only running rough on cold start ups more than likely its stiction

I was going to try some AR9100. Has anyone had luck with that product? It's about $50 cheaper per full treatment than Rev-X, from what I've seen.

AR9100-16oz FRICTION MODIFIER-INTRODUCTORY PRICE

Also thought of something else the dealer told me...they said the injectors were "leaking oil". Wouldn't this be more of a hard start when hot problem? I can't see an oil leak at an injector clearing up after the truck is warm.
