Update to the DIY: Today I completed another expanding coolant pipe job. When I finished the job, I got a check engine light and increased emissions message, and after scanning the OBD on the car. I had a code for misfire on cylinder #8. I took the intake manifold back off to see if something got in between the gasket. While taking the fuel rail off, I found a O-ring missing on the # 8 cylinder. I replaced to O-ring, put the intake manifold back on and problem solved. One more thing to check before you put everything back together if you choose to remove the fuel rail. Hope this helps.

I have done this job 7 times on 545s, 645s and 745s. This was the first time I ran into this problem so, I thought I would post it to help some out.
