Return oil tube leak
in 912 / 914 Technical Questions
7 years ago
Hi all,
I'm experiencing with an oil leak (rated one small drop in one hour) located in the the upper portion of the oil return tube of the cylinder 4, between the return tube and the cylinder head as I show in the figure attached . The engine is a Rotax 912 ULS and no overheating sign is present.
The Heavy MM section 73.00.00 page 75 say, if oil leak is present in that area, to remove and replace the tube following the detailed procedure.
Based on your and field experience, in these case of small leakage in that area, what do you suggest ?
Replace the tube in any case or keep an eye and see if the leak is stable ? I've seen in Internet some guys sealing the part with small amount of RTV sealant (the red aeronautical one) just outside the edge between the tube and the head.
Have you ever seen this last sealant solution ?
