How much does it cost to test injectors and who does it? I started getting fuel in my oil and i pulled the pass side injectors today. I cant see anything wrong with them but ive never dealt with fuel in oil either. Every other time it was them dribbling fuel. Where do they crack and is it usually visible? I dont have the driverside out yet. Also i know atleast one injector on the passenger side was replaced by the dealer. Is there a way to tell which ones? Also if anyone has a know good set of injectors for the right price i might be interested even if they are alittle oversized. I just need to get my truck running soon. sorry for all the questions.

OK i got all the injectors pulled today. 4 of them have the same numbers. 2 are remans since the numbers have a x through them. 2 of them look like GM replacements as the numbers are diffrent but they dont have x's on them. On the one original injector that was in #2 the ball popped out and all that is holding it in is the injector body. would that cause it to pass fuel into the motor????

That Exergy price isn't the suggested price to pay for testing. That's dealer cost and they don't like someone dealing for those cost.

Baseline Test of Injectors (Optional) Factory standard test points to factory specificationsRecommended only if performance of injectors is unknownSorts out damaged, worn or debris fouled hardware
Cost
Retail $450
Dealers$***.**

The 450.00 is Retail cost for Exergy not the dealer cost. But dealer cost is not much cheaper then that. The price I gave him for 25.00 ea Exergy would not even check but half of them for that price.
