2016 grand caravan rough idle

Asked by Aug 17, 2019 at 03:14 AM about the 2016 Dodge Grand Caravan

Question type: Maintenance & Repair

I have a 2016 grand caravan, with 3.6. It started idling rough. My mechanic is
telling me that the left head needs to be replaced and he hopes that fixes the
problem. Was wondering if anyone may have ran into the same issue and knew
what it might be.

Did he tell you what's wrong? Is the head warped? Are the valve seats damaged? Is there a crack in the head? By the response of "he hopes that fixes the problem," it doesn't seem that he's sure what the problem is. If the car runs, you might want to see another mechanic. Might just be a blown head gasket and this would save you from the cost of a head.

No he didn't say that it was warped or cracked. He changed the plugs and a coil (I think coil 6) and it didn't fix the problem so he said what he was reading was that this was a common problem caused by the left head. I haven't found any water in oil and thought that was an indicator of bad head.
