Reds are placed the escape multiple, shortly after walking, it is catalytic, v8, 7.5 lt, the converter was taken, the point moved, but they are still red, the engine works at a normal temperature. I don't know what the problem is, who can help me.
If they are very charred by ollin or oil residues, it is common to pass the other is that gases do not evacuate very serrated valves or obstructions in the line, at least I have seen that I have seen in similar cases.
I already check it and do not have what you indicate, but on the other hand the compressor injects air into the multiple and the converter, I do not know if that is the cause of the multiple temperature rising, do you know anything?
