The Northstar in the 1997 Eldorado developed a compression problem in number 8. A leak-down test revealed that the intake valve is causing the problem. A Caddyinfo Supporter will pick up the car in a few days and pull the front head. What we do from there depends on exactly what we find. Expectations are that we will do a valve job and put it back together. Watch this space for developments.

This is a collaborative DIY project with multiple Caddyinfo participants. As such, progress is subject to availability of time, and there will be deliberations and discussions that usually won't be publicly posted. Please be patient with this Topic.
