Repair is done and engine idles as smooth as a sewing machine. $6.50 for a new spring. Probably about 8 hours of total time into the job. Thanks for all the good advice and information everyone! Of course my wife and I are a little nervous about the rest of the valve springs now.

i think you need to go out and buy a lotto ticket. very lucky. odds of another spring being faulty is pretty big. odds of it happing to you even more so.

The 3800 I did ran aleast 30K with no issues after. It was traded in at that point. Like I said before valve spring rarely break. It has to be like a 1 in a million process/metallurgical defect. The chances of 2 in one car would be insane.

I just realized the PDF's I downloaded do not contain some of chapter 8 and all of chapter 9 and the index. Now I can't find my way back to the link to download them. I think I found it here on the forum... Help?:icon_frown:

Some of the manual are multi downloads. Make sure you get them all.

Thank you, thank you!
