Customer Question

JA: Does the light stay on, or does it blink?
Customer: It blinks, sometimes go out. At times the light comes on and stays on for few days that goes out and stays out for days. Only happens in idle.
JA: Are you fixing your Dakota yourself? What have you tried so far?
Customer: No, working with a shop. They ran diagnostic's and everything else checked good. That's when they did the compression check and cylinder leak down and discover the #5 intake valve was bypassing. Compression on that cylinder was 170,
JA: Anything else you want the mechanic to know before I connect you?

Hello and welcome! My name isCustomerand I would like to assist you with your question. I see the information you have typed above. What exactly is your question?

What is the fix rather then replacing the engine as recommended by the shop
Expert:  Amedee replied 1 month ago.

The cylinder head or heads would need to be removed and sent out to a machine shop. They would then pressure check and resurface the cylinder heads and even possibly replace the valve or springs as needed.

why are they suggesting replacing the engine instead.
Expert:  Amedee replied 1 month ago.

You would have to ask them that question. I suspect because it is less labor to replace the engine rather than just replacing the engine.

Sorry, I meant to say it is less labor to replace the engine rather than to remove and reinstall the cylinder heads.
