Bruce,

As a matter of fact Lycomming has an AD out that wants the engine  
torn down if it has been over 10% of maximum RPM for more than 3  
seconds.

Here is my problem. I have had the engine out 4 times and 100% of the  
time that the engine has been taken out it has not been put back in  
correctly. The engine tear-down isn't the problem. The problem is  
getting all of the accessories off and back on. The last time my  
engine was taken out, 2 of the iridium plugs were dropped and broken,  
the timing on one mag was set to 50% BTDC and the prop governor cable  
came loose within 6 months. I can guarantee that if the engine is  
taken out, it will have major problems.

My intention is to first of all find and fix the problem and then to  
borescope, compression test and check the oil for metal before  
getting a ferry permit to bring the plane home. I sure hope that it  
is not the crank plug.
