I decided to go ahead and change the CCV system yesterday on my 2.8 M52TU, without removing the manifold. On a couple of occasions when flooring it I've had a big cloud of smoke come out of the exhaust plus I had a small split in the hose across the top of the inlet manifold. It all came out fairly easy and 2 out of the 3 connections look straight forward to feed through and fit to the main unit.
My problem came trying to attach the smaller angled hose through to the top of the manifold. I was looking at @Lee's guide which showed most of the things that needed to be moved out of the way. I connected this hose to the main unit first as its a push then twist connection and fed it up to the top of the manifold where it connects. No matter which way I tried I still could get the main unit to go far enough back into place. It's impossible to put it in place first as well, then try to feed the hose through and push and twist it into place. I spent probably 3 or 4 hours trying all different ways but it wouldn't work.
In the end I decided to unbolt and move the power steering reservoir out the way which gave me access to the connection on the main unit whilst it was in place. There was just enough room to push the hose in and twist it up to the top of the manifold, securing it in place how it should be. Once I had this access it was connected up in about 5 minutes
then the rest was straight forward.
So if anyone thinks of changing the CCV system in situ, make sure you move the power steering reservoir out of the way unlike I did
All now seems to be running fine at present, just got to check for any leaks in the next few days.
New kit ready
This was the split hose, tapped up for the last few weeks. Plus a broken connection on the top of the hose that was a bi*** to fit, held with a cable tie
New ones in, forgot to take photos of the main unit though!
And it looked like it was well overdue a refresh
I did also notice the small vacuum pipes that connect to the cannister and route upto the back of the manifold and fuse box are crumbling so I've got some new hose on the way to get these changed.
