Hi all,

Last weekend I started the engine of my Sierra Cosworth 4x4 after 6 months and it now suddenly produces big blue smoke. It happens after revving from idle and than shut the throttle. It doesnt smoke at startup. I drove it for about 8 miles and couldnt see any smoke coming from the exhaust. It has never done this before.
I have an almost brand new T34 and I took off the hose from the turbo outlet to the intercooler. It was totally dry not a sign of oil. The engine has only done about 60.000 miles

Could this be from standing too long and not starting it up during winter?

Hope someone has a clue.
