Oil Catch can

[terrya]

Hello All,

Terry from Australia.

Can someone advise me where to buy an oil catch can and fittings for my R44

Are there different brands, which one is best suited and what are they to buy and who is the supplier?

Happy if someone can help.

Machine pushes a reasonable amount out of breather, maybe 3/4 of a qt per hours running. Seems to change depending on running conditions. It's a waste and makes a mess of undercarriage.

Only fill to 7 qt on stick not 9. our days can be hot so I have not tried to run with less oil

Cheers

Terry

You might want to talk to an engineer about this. From what I was told, this amount of oil loss through the breather isn't normal even in an R44, and could indicate that you have excessive crank case pressure, possibly from piston ring blow-by. You could have one or more cracked- or worn out piston rings, or a hooped cylinder. Compression tests alone also aren't all that reliable at detecting these issues.

You are correct regarding comp test's, that much blow by suggests problem with rings or cylinders

We do comp test & leak down test

Also blow-by is another way using a flow meter ( this is not a book procedure)

This is a way to see how a trend is developing, before & after doing rings etc

Dividing an engines maximum horsepower output by 50 will give you a ballpark number for how much blow-by you would normally expect to see.

Terry,

 

Sounds like you are doing everything correctly, must be a temperature thing like you said. I always filled to the lower yellow mark and never had problems, max summer temps where I did most of my flying rarely exceeded 90 degrees F.
