We have a Bell B30E and it’s been leaking oil out from around the oil fill cap. The cap is tight but it’s leaking oil. I believe it must be building pressure and pushing past the seal. Has anyone seen this before? Should we be investigating this further?
Make sure your crankcase breather is free and clear. Is there a lot of blowby? If the breather is free and clear and you have very little blowby then replace the filler cap.
We’re back to work tomorrow. We’ll check out the breather and see what the last service date is marked at. No the machine doesn’t have excessive blow by. Fresh machine with less than 2100 hours on her.
