This is with precision same syndrom as I have in my OH-XRT. It has been
totally dry and w/o leaks since 2007 until last winter after 5 years I
changed all the rubber hoses and pipes and decided to install also those
blue silicon hoses. During the last season I have seen after every flight a
teaspoon or couple of coolant dropping out (port side). That makes me
nervous. All the joints have been tightened several times.
Attached a picture which tells what is happening when the hose (blue
silicon) is a bit too near a muffler /silencer. But that=B4s a different
story.
