Hi Neal,
I don't have any mechanic experience
Can you give me more details?

Then I would not attempt this repair. This is not something for a beginner, there are too many small issues for me to walk you through it over the internet.

 

The labor is only 2.3 hours so it would not be too much to have it done by a mechanic.

Ok, so if you can't tell me what to do in details,and i need to go to mechanic for this, why i need to pay for it?
