I'm slightly confused by the plumbing here. On your ZVH you drilled the block to an 18mm hole and put in a separate line which I thought was the breather going to your catch tank, I also thought the catch tank had a line from the rocker cover breather. I thought the fumes went out of the catch tank filter and the excess oil gathered in the catch tank which had to periodically be drained off. I asume there is no PCV in these lines. Confusion is that is the hole you drilled out in the block to drain your catch tank or is the breather and the drain is a different line? Do you vent any gases into the engine inlet or plenum? One thing I did notice on the Garrett web site is that the turbo return should not be in an area that receives backwash from the crankshaft. I think but haven't looked that the crankshaft views directly onto the breather hole. I guess to solve my confusion, could you please explain your connections to the catch tank Jim. I have noticed on one web site an alum block to screw directly onto the block in place of the breather to take the line to the catch tank. Unfortunately I seem to have found lots of bits of info on this, but nothing definitive. I am now trying to make the sum of all the parts make a whole. As is usual with things like this there is also lots of conflicting information around. Thanks for the info on the turbo Jim and Hamish. I had always expected some play for the reasons you mention and when guys say no play I am a little sceptical, but this did appear excessive and as Hamish mentioned I am a litle concerned by the flow to the turbo resulting in an oil pressure drop. I am still to sort out where to take the flow from as the Black top doesn't seem to have the additional hole you mentioned in a previous post. It probably will end up coming from the pressure sender unit hole - a task for next weekend!! Thanks Nigel
