• The Biplane Forum is a large global active community of biplane builders, owners and pilots. From Pitts to Skybolts, to older barnstormers, all types are welcome. 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. We are also a great resource for non biplane users, since many GA aircraft are built the same way (fabric and tube construction).

Engine Oil has metal

Hey all you Pitts drivers with IO-540's My buddy was flying the other day and he was finishing up on his routine for the airshow when he noticed on a negative push that his oil pressure was around 33psi so he went to upright position and noticed the oil pressure came to 65. Normal oil pressure for this engine is around 78psi. What could cause this? We did a compression check and the number 4 cylinder was holding 77/80 but we heard a lot of air escaping out the oil dipstick. We dumped the oil and in the oil filter there is shinny metal almost invisible but you could see it with a magnifying glass. We are going to send the oil to be analyzed by a shop. Has anyone experienced this before?
