Strange exhaust query - one hot cylinder?
Posted: 12 Apr 2016, 11:56
I recently had a stainless steel exhaust fitted to my bus - 2.1 petrol.
When I picked it up, the guy told me that they had test run it at 2500 revs for twenty minutes (vehicle stationary), and he had noted that one of the exhaust manifold pipes got red hot. It's the front left side (looking forward) pipe, and he thought it might be running a bit rich. Should I be worried about this? I suppose that normally at 2500 revs, you'd be driving along, and the airflow would cool it down, but if the other pipes aren't heating up, does this indicate a problem with the hot one, and what (if anything) could I do about it?
