Hi all.
1.9 MJet 2006
I have a leak of some sort coming from the top of pipe 4. It is not a split but seems to be coming from the pipe seal.
It seems like oil which is then running all the way down the pipe to the inter cooler.
Could anybody tell me what this pipe is and what it does?
I have tried to tighten it but the top bolt of the two does not tighten, it seems like it is threaded...
Thanks.
