If one has put 8.5:1 compression cylinders on a Lycoming 0-320-E2-A does this AD apply? As I read the AD, it applies to engines with hollow cranks of 160 hp if O-320 and all O-360 engines. Has anyone here had issues with this. My engine logs have never mentioned this AD but recently has had cylinder assemblies changed to 8.5:1. The E2-A is a 150 hp engine from a Cherokee 140.
How big a deal is it to remove the "freeze plug" from the snout of the crank and inspect for the possible corrosion pitting?
