We pulled one of the valve/rocker covers off to replace the seal and found the inside of the valve cover painted. This is on an IO-470VO.
Seeing this has me stumped. I have never come across paint on the inside of a cover. Then again, this is the first Continental that I have opened up.
In my mind this is a horrible design and it can't possibly be like this from the factory. The paint was bubbling in a couple of places and it appeared that it was just a matter of time before some of the paint came off and entered into the engine itself.
I double checked with 2 different A&P/IA's and both agreed that they have never seen something like this.
Any thoughts?
