On my 1.4T I had a leak on return hose called "hose degassing".
I solved it with new O ring, didnt have to change whole hose.
I will post dimensions of O ring i installed.
I am not sure if you have parts like this on your type of engine.
My mechanic told me that the Astra J is prone to have this kind of leak or leak on the part below this hose.
I will post two pictures of parts.
When I fixed the leak on O ring it was fine.
Then in 10 days it started to leak on the lower part. So I ordered it and waiting to come
