Right finally got my turbo setup up and running and ran really good on boost nothing went wrong until...
the dreaded blue smoke appeared belching out of the exhaust (nearly hung myself) well anyway did some research and some tests to find out it had to be leaking through the valve stem seals which it clearly was as they had lifted up the stems. Next day i whipped the head off to replace them, took it back out and they rose up the stems again thus leaking oil! My only guesses this is happening due to the DOUBLE VALVE SPRINGS installed, seems to me that the inner spring is catching the seals and lifting them up? does anyone else use doubles? if this is the case would i be okay to just run single valve springs? if so shall i uprate?, just want to drive it without smoke screening everybody lol *tongue*

Low boosting for now.

MRA do some good valve stem seals, but they have gone bust.

Maybe try glueing them down

There are 2 issues causing this the main one is ....on high revs the inner spring floats around poping the seals off, if you pm me I do some hasterloyd inner spring retainers to eliminate this you really need the double springs.
