Hi, all. I have a minor problem, in that I collected my car from local  
garage after they replaced the head gasket, on the drive home noticed that  
every time I turned right there was vibration. On the drive I popped the  
bonnet to see if I could see anything around the steering to cause this  
oddity. All seemed OK until I noticed what I think was an error on behalf  
of the garage mechanic. There is a hose connected at one end to the inlet  
manifold traverses the rocker cover to the turbo. At the turbo end in the  
bend is what appears to be a plastic valve with a narrower plastic  
extrusion leaving it. I have a sneeking suspicion this hose has been  
fitted the wrong way round, am I correct? Of course I will be taking the  
car back after the bank holiday, for them to check the peculiar steering  
problem and of course make good anything else. The problem is of course  
they are not volvo agents. I would like to be able to tell him where this  
plastic piece should be connected to, but more importantly is it safe to  
drive? I would gratefully appreciate your input.
