Hello VAF...
Looking for recommendations on cylinder shops.
In my recent thread I was having an issue with run away CHT on number 2. I thought it was resolved, but was sadly mistaken. After checking everything else the last thing to do was to remove the cylinder. What we found was that the cylinder is pushing oil. The face is valve is blackened with burnt oil and so is the top of the piston. We expected to find an obvious reason for why this was happening, ie...a broken ring, but did not.
The heat is coming from the burnt oil deposits which are turning red hot. On my last flight everything was fine until again the number 2 CHT rapidly started increasing....and continued increasing to 450 after I pulled power to near idle.
So now I will be calling around to some cylinder shops and check out my options for overhauling this cylinder. Figuring on at least a new piston and rings. I have chrome cylinders...not sure how the new rings would seat without honing. Can the chrome cylinders be rechromed?... what about NuChrome...?
OH Cost vs new..these are angle valve cylinders too..
