Yak52TW with 300 TT: oil pressure gage flickering up & down taxiing in after landing.oil quantity 11 on stick after shutdown( started with 12).

1 comments:
Mr. Anderson
August 20, 2025

The flickering of the oil pressure gauge on a Vedeneyev M-14P engine in a Yak52TW after landing could be due to a faulty pressure gauge or a loose connection in the oil pressure system. The oil quantity reading of 11 on the stick after shutdown indicates adequate oil, so low oil level is not the cause. Other possible causes include air in the oil lines, partially clogged oil passages, or a malfunctioning pressure relief valve.
