Blue Smoke on Startup
Here we go again........
The following morning after a thrash when i start her up there is a big cloud of blue smoke that disappears after a few seconds but doesn't return during driving or on boost or idle. It is only there when you first start her up..........?
Piston rings, valve deals or turbo?
Suggestions please

Whilst on boost you get blowby gasses which pass the piston rings and enter the crank case this can stir up oil vapour, this blowby gas/oil vapour mix then gets dumped out of the crank case breather into your turbo intake pipe, as the oil vapour passes through the turbo,intercooler and intake manifold the oil seperates from the air/gas mix and sticks to everything, the oil can build up in the intercooler and intake manifold after hard driving, it then settles in the heads and or cylinders so that the next time you start the car you get a chuff of blue smoke. Mine did it all the time after hard driving until I fitted a catch can. The oil deposited from the crank case in the intake can clog up the idle air control valve, reduce intercooler efficiency, cause boosting issues by clogging up the solenoid and MAP sensor and reduces the flame front of your fuel.

I think I need you to look at my car that is a comprehensive explanation Iain, thanks. Any idea how I can confirm whether it is the problem you describe or the turbo seal one?

Will this do the job? Or do you need to buy a decent spec?

The worst source of oil is from the crank case so putting that to the catch can on its own will help a great deal, you can easily add ports to the catch can if needed. But one of the ports must be to atmosphere or back to the intake.

You need one port to be to atmosphere, if you plumb the 2 cam cover breathers into 1 and the crank to the other then there is nowhere for the blowby to go and I have seen an Impreza throw oil out of the exhaust (I guess either past the pistons and/or out through the breather due to pressure buildup in the crank case).
