Not with me, I completely agree. I was just asking the logic behind leaning to cool an engine as leaning always increases the heat until you go lean of peak. However, leaning to peak or better results in the most complete fuel burn an less grungy deposits floating around in the cylinders which, from my discussions with various mechanics, can degrade the life of internal engine parts. Apparently the excess fuel can harden and basically your left with little hard particles that can gunk up components, similar to the spark plug build up we have all experienced with a mag check, but on a much smaller and long term scale.

As long as you have CHT's and can ensure you are not out of the green I always lean as far as possible, I don't usually go lean of peak though as the excess vibration isn't good for the rest of the aircraft. I also don't lean with the EGT gauge, I lean till it runs rough then go back in till smooth ops again and monitor temps.
