In addition to our active community, our content boasts exhaustive technical information which is often sought after for projects and maintenance. This information has accumulated over the 12+ years the forum has been in existence.

    The Biplane Forum is a private community. Subscriptions are only $49.99/year or $6.99/month to gain access to this great community and unmatched source of information not found anywhere else on the web.

ECI Cermanil Break in on Pitts

Anyone have trouble getting rings to seat on ECI Cerminal cylinders? The engine in my Pitts was just overhauled and at 6 hours the compressions are really low and there is lots of oil coming out the breather. I just bought it but the previous owner was flying it at 2500 RPM for break in. I suspect the engine was not developing enough manifold pressure to break them in. Any experiences are appreciated.
