I am looking for anyone who has had dealings with a Northstar Engine rebuilder located in Wisconsin. Please post you story good or bad with the year and make of your Cadillac.

 

replaced the engine. Timeserts or helicoils will not hold. I promise.

 

Go to ebay,,there are several low milage used engines there,,some are near you. REPLACE anti freeze every year!! It will cause damage as it gets older!! You have a deeper problem if you have done that damage to engine.
