I have a ‘97 Trooper with a valve tick. I called a shop and I was told by the shop this isn’t an issue that can be fixed, just replaced due to the hydraulic valves. Is this true? Or any ideas what to do?

 

A SeaFoam Engine flush is worth a try.

 

I'm guessing you have a bad hydraulic lifter. Are you saying that they were just replaced? Can't imagine why it can't be fixed. You can likely find the bad cylinder with a compression test and just change the bad one or change them all. It's not that hard and they're not all that expensive.

 

Here's an old school fix: Marvel Mystery Oil. Read the can, pour the magic red sauce.

My ticks went away.
