Worked great!
Ordered this to fix stripped threads in my BMW 3.0l after an overheat. Everything was well made and clear instructions. I was able to do all 14 bolt holes in about 3 hours.

Saved my block
I find all Time-sert kits are very well produced and work well the first time. The technical support the company gives both through email and by phone is also excellent, if not timely. It may take a day or two to get a response, but a live human actually responds and I have received excellent information from them.One note, these inserts will rescue your block, but are generally one or two time use before requiring replacement.
