I assume there is a seal that needs to be replaced. Any info would be greatly appreciated.

There should be a comment somewhere in the aircraft operating manual that recommends that you run the engine up to about 60-70% (pulling that number from memory) for about 30 seconds or so, before shut down. The same applies to long sitting times at idle while waiting for the tower. Simply run the engine up for 30 seconds or so, and problem solved.

If you are in this situation, forced to idle/taxi for some 15 minutes or more, what's the best course of action? Question for both scenarios - before a shutdown or before a takeoff. Thanks.

I see this quite often on an Auto converted M14PF. As soon as a see a cylinder starting to go backwards CHT wise a run up is needed to clear the offending plug. For me this is an issue any time their is extended taxi times and or holding before take off.

If there is, replace both the inner and outer seal on the piston. Oil inside the hub will spew out on to the blade roots when the prop is spinning. Oil inside the hub is caused by a weak inner piston seal. Check your log books for the last time the hub was disassembled, cleaned and all bearings and races regreased. If it hasnt been done in the last 200 hours, it would be a good idea to do so. Also check the log book to see if the collet seals have been replaced in the last 600-750 hours. Again, if there is no record of it being done, it would be recommended they be replaced as well.

From: "1906" Thanks Ttail. Did you make the hoses & choose different fittings yourself? I saw your setup in a different picture and it those pieces don't look like the standard ones that come with the Airwolf kit.

An internal probe failure typically results in a maximum reading as does an open circuit in the connection plug or a broken wire. Checking the engine oil temp. probe could be as simple as switching from oil in to oil out since that is two different probes.
