Winter & cold engines
I have a 337H & I had a problem in winter with my front engine running cold. The oil probe would never get above 150 degrees. There was always water droplettes on the dip stick & oil filler cap. My A&P made a aluminum plate that slides in above the oil cooler. Now the temp. gets up to 180 degrees & the water disappeared. I put that plate in place in Nov. & remove it in March.
All my flights are in the north eastern states.
