Well,as always when you ask more people,or find more parts for a car,you get more answers and more potential issues.
What I wanted to do was get the top end of the engine sorted....
So,the cam cover and VTA breather kit is sorted and waiting to go,and that left the time for getting the valves etc done.
Now the idea of getting the cams done entered the mix,and Cat Cams do some very nice products for the TFSi so I've had some advice and a good look at those.
Look good,dont they....and compatible with VVT etc.
But not entirely compatible with the valves I'd chosen as the lift max for the Ferreas is quoted as 11mm and these lift a bit more,so that's another one to research.
If the worst comes to the worst,then it may be better to keep the stock valve train,and go with these cams,as the power and torque gains are substantial.
More phone calls........
