Just read about another story today.
This is Why I keep telling people to invest in a good engine monitor and an Advanced Pilot Seminars engine class. This guy should too.
So, I get the plane home from annual and the EGT gauges (single point) no longer line up at idle or even take off where they used too. The right one reads off the chart low, whatever that means, and the left one reads higher. On top of that the right engine CHT(single point) is reading higher than normal quickly showing 400 degrees on climb and that is unusual. Also the right oil temp is noticeably higher than normal usually a tad over 150; now 190-200. LOP at 12k I still cannot get the CHT below 400 when it's usually 350 easy. Then I noticed on the mag checks there was hardly any drop when switching mags; this is unusual; I usually get at least a 50-75 rpm drop off. So finally I ask another mechanic and suggested maybe the mag timing was off. Comments?
Maybe the mag timing is off?
Ya kidding me! No doubt and it is advanced what's worse!
