found small leak on isv cured that . blocked off throttle body hose and rocker oil pipe hose pressurised from maf wont hold pressure at all through turbo . can here air in engine through oil pipe from turbo. started up this morning blue smoke from exhaust
over 4 minutes until it burnt off . certain now its turbo

If you pressurised the system with the breather connected, that's the cause of your blue smoke for sure! You've forced oil in to all sorts of places that it should go BTDT a few times.

Block off the breather and test it again - that's what you need to do really.

I guess

a) he didn't read this in my boost testing link:

"Here is a table that outlines the various boost testing options based on the above diagrams. Note: The table was set up to isolate certain components. Many people, most notably prj (dmitri) have suggested that the simplest method of boost leak testing that captures all the possibilities in one go is to place the pressure bung in "A1" in the diagram and disconnect the hose from the cam cover to "A3" and plug "A3", leaving the rest alone. This falls some where between test Option 1 and Option 3."

and

b) I need to modify that table eliminate Options 1 and 2 because they don't include plugging the "A3" cam cover connection.
