My mom has a 98 durango 5.2 l v8, and she told me she thinks she might need to replace her egr valve, well I've been researching and there is no egr for this model, however it might be the pcv. Now my question is if she thinks it was this that was wrong with it what else could it be? She recently replaced timing belt and water pump, fuel pump, and alternator. She wasn't very descriptive but was curious if y'all could help me please and thank you.

 

a description of the fault is required. what is the truck doing that seems out of order?

 

What is the problem?

 

The trucks having timing chains, no timing belt.
