My Aerosport Power IO-360 #2 Millenium Cylinder developed a sticky exhaust valve at a little over 400 hours. It was a very subtle problem to diagnose but that is another story.
I have never removed a cylinder but found removal and reinstallation to be very straight forward. It took very little time. Off it went to Bart at Aerosport Power for a full check up.
Bart reamed the guide, honed the cylinder, replaced the rings, lapped both seats, and returned the cylinder to me in less than a week. It was returned with a package of new gaskets for exhaust, intake, valve cover, push rod tube o-rings and seals, exhaust flange nuts and washers, cylinder base o-ring, etc....
total charge = freight back to me, $26.
That is over and above any expectations I would have for an engine with 400 plus hours.
Aerosport Power is a class act.
I am taking this opportunity to redo my intake ramps and front baffle seals as I have never been happy with the fit, so, while they are off, I will redo them and hope to capture some more cooling air in the plenum.
