BMW Z3 Project

I have been able to drive the car when the weather is good.  So far I have 325 miles logged. It is running great and is a hoot to drive.  If you punch it, the rear end will break loose. I tape marked the coolant reservoir and have been watching the level.  So far the coolant level has been stable.  So, I think the cylinder head is crack free. I am a little disappointed with the check engine light.  I cleared all the codes and after running 100 miles the check engine light returned.  The code was for catalytic converter efficiency.  So I think the previous engine dumped enough coolant down the exhaust to case damage to the catalyst.  I heard you could clean the catalytic converter with citric acid.  So I may try that. I currently have the seats out of the car.  I have cleaned the leather, shampooed the carpet.  And I replaced the worn out bushings in the power seat adjusters.

I have been looking for a car project for several years.   It was tough to decide what make and model of car, but finally settled on the BMW Z3.   I watched Craigslist in my area until one day this car appeared.   The engine was clearly in trouble, the exhaust was smoking white.   The owner admitted it overheated and was never the same.   We agreed on a price and I rented a U-Haul trailer and pick up truck.  I knew this was a gamble and the worse case scenario would be a replacement engine.  So the journey begins.
