I have noticed a pipe that has a perished junction on my motor. This pipe connects to the breather pipe off the valve cover. Here is the link to the pics' slideshow.Anyone with some helpful contribution is welcome.

I managed to buy the new breather pipe for £41.50 from the Stealer. Unfortunately it is a Stealer only part. Part number: 06B103211H. Apparently there is an old part number but that has been replaced by the one above. I have included a link for the pictures of the pipe. It is a pain to take out and replace without uprooting the intake manifold. With tonnes of patience, I managed to do it without removing the intake manifold. This was made possible by disconnecting a wire that is connected to the generator/alternator. and removing the bracket that stiffens the dipstick guide tube. The pipe is secured by a green retaining clip. easy to remove but very fiddly to re-install. The bottom of the breather piper has copper/brass stiffening end-feed. It is a tight fit into the new pipe. I managed this by dipping the bulky end into a bucket of boiling water. the hard plastic softens a bit and then one can force the copper/brass end-feed. The rattle is now gone and less oil consumption!
