Hi,
For some reason, I can't access the link you provided. As far as gasket cement, no. There shouldn't be anything like that used. Where are you seeing it? Can you upload a pic for me to see?
Also, the temps seem okay. Normally, the outlet is between 75 and 100 degrees hotter than the inlet, but we only have a code for one side.
Did you try deleting the code to see if it returns? It could have been a fluke that the light turned on.
I don't know if you have a live data scan tool, but if you do, check the post-O2 sensor voltage. It should be around.5v. Compare it to the pre-02 sensor. If they are the same voltages, that is a good indication the converter isn't working.
Let me know.
Joe
