Yes, it can be a very common issue for certain engine families and generally has no impact on longevity or performance.


Thank you both. I suspect that is the answer I will get from the dealer tomorrow.

If there's no long term issue, I'm fine with it. I'm just a little cautious after my 2013 Pentastar engine failure.

I think that was just a bad batch of engines. My dad's is a 2012 with 300,000km on it and running just as good. He uses Fram Orange Cans in all of his vehicles normally (but Wix in this one) and the cheapest conventional oil he can find that is on sale. He doesn't even look for the MS-6395 spec it is supposed to meet either. He tows with it too.

I found them. #10 in the drawing. Only $3.35 each.

Google search turned up a wide spread problem with the Pentastar V6 ticking. After awhile it goes from ticking for 1-2 seconds when cold, to ticking all the time none stop. Chrysler doesn't want their customers knowing about it, but it's all over the internet.

Correct, they are not expensive, it is replacing them (the labour) that gets costly.

You look up ticking for anything, you are going to find results, it definitely isn't isolated to the Pentastar or Chrysler.

It's actually not that bad to do so long as you are careful to time the cams again properly.

This video shows how easy the camshaft is to remove. He doesn't even remove it fully to take out the roller-rocker he's replacing.

The 2.0L in my Kia Soul has an issue with start-up noise from lifters draining down.

It clatters like crazy for a half a minute or so some start-ups...but is completely silent on others.

10W-30 oil, and an OEM Kia filter has reduced the instance of this a LOT, but it still does it a fair bit.

Still thinking of experimenting with Mos2 and thicker oils to see if I can get it to go away.
