When is it Time to Replace Your Common Rail Injectors?
You're probably wondering just how you know when to replace your injectors. Here are a few things that can indicate it might be time to have your common rail injectors looked at.
One symptom you might notice right away is poor fuel efficiency. You might also see blue smoke coming out of your exhaust.
If you smell raw fuel coming out of your exhaust, it's time to have your injectors checked.
Have you ever noticed fuel in your oil? If so, you might want to take a look at your injectors. This is because you have the potential for excess fuel to get into your cylinders, and then dropping down into your crankcase. It can also cause return leaks, if it's underneath the valve cover, getting into your crank that way.
Engine misfires can be a clear sign that you need to replace your diesel injectors as well. You can have one or two cylinders down, or it can just be a wiring harness as well, but it's always something to check.
