Have a 10 hr since SMOH O320E3D that has the CHTs run up very rapidly to 425 plus on take off and have to throttle back to keep the temps down for take off climb. Once the engine warms up in flight the CHT issue goes away and settles down in the 375 range even at WOT. Oil pressure is around 75 and oil temp stay in the low green
Initially though it was a newly overhauled thing but it does not seem to be clearing up at 10 hours. I am going to replace all the baffles with red silicon baffle tape this week to see if I can get a better seal but don't think it is causing this issue.
What CHT range are others getting on take off?
Could this be a vernatherm problem? Just need more time? Other ideas?
