Last saturday we were cruising at 11000' and at 28" and 2500rpm our cht was rising to almost 400 degrees. It seems like we all of a sudden started having high cht for no reason. Have you noticed this with any other 4p's. Jeff Jeff, I have had a similar experience. I have over 400 hrs on my 4P and one time I was flying for over 1.5 hrs level at altitude running LOP and within about 1 min. I had number 3 CHT just start marching up to 420* where I had my alarm set. I went full rich for a while until all temps were back to my normal high and then continue back to LOP. I never saw that situation again. For the record, I now only run ROP because of too high EGT's when LOP and I have replaced two complete sets of cylinders in my 400 hrs all with exhaust valve stems and guides warn beyond service limits.
